By insulating the roof from the inside with your own hands, you will achieve two important advantages. Firstly, you will be able to get rid of heat losses, which in houses with uninsulated roofs amount to 15%. Secondly, by insulating the attic space, you will get additional space that can be turned into a full-fledged living room.

To execute effective insulation roof from the inside of your home, you will need to use the appropriate materials. They have special requirements that must be taken into account when choosing.

Density. Thermal insulation properties are higher for those materials whose density is low. For roofing, it is recommended to choose an average density;
Thermal conductivity. Try to use materials that have the lowest thermal conductivity. So the protective layer will practically not release such significant heat from under the roof;
Water absorption. This is the property to absorb and retain moisture in the pores of the material. We don’t need to accumulate moisture, so when choosing thermal insulating glass wool or mineral wool, be sure to check whether it is hydrophobic;
Resistant to low temperatures. Most roof insulation materials can easily withstand temperatures as low as -50 degrees Celsius. This is quite enough for any region of our country. But check how many cycles of freezing and thawing the material can withstand;
Fire resistance. The material must not present a hazard in this component. You can get rid of this disadvantage of some heat insulators through special impregnation;
Chemical resistance. The selected thermal insulation should not be destroyed or lose its properties under the influence of chemical substances. But you must not allow contact with them either;
Environmental friendliness. Since many equip the roof space under the roof in residential attic, you need to use only safe, environmentally friendly materials based on natural or non-hazardous components.

Insulation materials used

Taking into account all the requirements for materials for insulating the roof from the inside, the choice will be between several optimal options for heat-insulating roofing materials.

Mineral wool. This is the most popular way to insulate a roof from the inside. Choose basalt wool; be sure to ask the store for a product safety certificate when purchasing mineral wool. The dimensions, thickness, and geometry of the products are selected in accordance with the parameters of the roof itself.
Glass wool. Not so long ago, glass wool was used very widely in matters of roof insulation. But now the emergence of safer, environmentally friendly materials has brought glass wool to the background. The thermal insulation properties are not bad, the efficiency is high level. But when insulating a roof with glass wool, be sure to follow safety precautions, wear protective suits, gloves, goggles, and protect your respiratory tract from glass dust. For allergy sufferers, such material is contraindicated.
Polymer insulation. These include slabs made of polystyrene foam or expanded polystyrene. At the price, it is a very attractive option for roof insulation, but in practice it has its drawbacks. To begin with, expanded polystyrene and polystyrene burn easily and produce copious amounts of smoke, which is dangerous to the body. They should be chosen for roof insulation only in situations where there are no alternatives.
Expanded clay. If you have insulated the floor in your house, expanded clay will be very familiar to you. It has excellent thermal insulation properties, but it is incredibly difficult to use when insulating a roof from the inside. Theoretically, it is possible to use it, but in practice, not all experienced craftsmen undertake such work.

Stages of roof insulation

Now we can begin to consider the main stages of work aimed at insulating the roof with inside. First, we advise you to watch the video instructions and familiarize yourself with all the nuances of thermal insulation visually, using the example of experienced craftsmen.

Process internal insulation roofing includes four main stages.

Installation of a waterproofing layer on the roof. It is best to lay the waterproofing layer at the installation stage roofing material onto the roof surface. The material is mounted perpendicular to the rafters, maintaining a slight sag. The smooth side of the waterproofing should face up. Be sure to glue the strips of waterproofing fabric with tape to prevent the formation of cracks and gaps. Then on rafter legs it is required to fill the counter-battens with the help of bars, and lay the sheathing of boards on them. Laying the roofing material begins on top of the board. If roofing coverings have already been completed, the waterproofing layer will have to be installed under the rafters using a stapler. All joints are carefully taped with tape.
Installation of thermal insulation material. Take thermal insulation mats required thickness, lay them between the rafters. Laying should be done using a spacer or using a rough hem. The hemming is made of thin slats, fishing line, and twine, which are fastened with nails to the rafters. Fill the entire space between the rafters with mats of thermal insulation material. Excess elements are cut off with a sharp knife. If you want to achieve the maximum effective thermal insulation In order to equip the attic for living space, all layers of material are laid offset from the bottom seam.
Installation of vapor barrier on the roof. Vapor barrier films have one smooth side, which must be laid in the direction towards insulation material. The rough side is responsible for absorbing moisture vapors and is therefore directed indoors. It is very important to lay the vapor barrier film correctly so that it can work effectively. By mixing up the sides of the installation, condensation will soon begin to appear on the surface. The material is mounted with a stapler, the joints are connected with tape.
Installation of profiles or guide bars. They are necessary for the installation of cladding decorative materials and creating the necessary ventilation gap.

Foamed roof insulation

Today, roof insulation using foam insulation is becoming increasingly popular. A striking example is polyurethane foam.

The method of roof insulation in this way has several features:

The roof does not require additional preparation from the inside;
The roof sheathing must be solid, carefully treated with antiseptics;
For spraying polyurethane foam on the roof, use special installations. They provide pressurized carbon dioxide. In the video you can see how they function;
The method of roof insulation with foam insulation requires the invitation of specialists. Purchasing the unit is not financially profitable;
A layer of foam is applied to the inner surface of the roof, achieving the required insulation thickness;
When the foam dries, it forms a layer of waterproof, seamless material on the roof that has low thermal conductivity;
The only drawback of insulation with foam insulation is its vapor permeability. To eliminate it, you need to equip the attic with an exhaust system. But it is only required for arranging a residential attic.

It is not difficult to insulate the roof from the inside with your own hands. But before starting work, you need to study the theory, choose best option insulation and follow the sequence of laying layers of thermal insulation.

- almost the most main element in the house. It protects the building from precipitation and makes it possible to organize normal conditions in the house.

And like other structures, it almost always requires high-quality insulation. Especially when it comes to unprepared roof structures made from ordinary slopes.

Here, the lack of insulation will simply be a fatal mistake, which will lead to a serious decrease in the temperature in the house.

1 Features of insulation

Do not be mistaken in thinking that you do not need roof insulation if you have an attic space. Most pitched roofs are always equipped with an attic space.

This is possible due to the fact that the slopes are formed at an angle in any case; they are mounted on special supports. Unlike the same roofing material, which flat roofs insulated immediately on the floor.

But even in the case of roofing felt, it is necessary to take care of insulating the roof with foam plastic, penoplex or other suitable insulation.

The presence of an attic, of course, creates a kind of air gap, similar to a veranda or dressing room at home.

But if you are considering the design of a slate roof or other similar solutions, then the entire system is so flimsy that it is simply not capable of retaining cold air, which means that the attic does not fulfill its functions.

If we are talking about processing the attic, then there is nothing to think about at all. The attic roof must be insulated, otherwise the house will always be cold.

We also note that when treating an attic, it is necessary not only to tightly lay the insulation, but also to seal it with a vapor barrier film, and also think through finishing solutions.

And let us immediately note that finishing will largely determine the method of insulation pitched roof and how much time and money you will have to spend on this process as is the case with.

2 What material to use?

Builders pay serious attention to the selection suitable material. Indeed, it is the insulation that determines what properties the structure will ultimately have and how effectively it can protect you from the cold in the future. The prices for all the work depend on it.

In your work, you can use a wide variety of insulation materials, but in most cases they use only a few options, which have proven themselves to be the best.

So, when arranging thermal insulation for a pitched roof, they use:

mineral wool;
Styrofoam;
Polyurethane foam.

Let us now analyze each of the presented materials separately.

2.1 Mineral wool

Mineral wool is very often used when insulating an attic or ordinary slate roof. And in general, in this regard, it is rightly considered number one in the world of insulation.

2.2 Expanded polystyrene

You can also use polystyrene foam for insulation, it’s good. At a low price, it has almost the same characteristics. Same as the previous material discussed. Absolute hydrophobicity and lack of reaction to external influences make it very durable.

But polystyrene foam burns in fire and has a vapor-proof structure. And if you can still somehow cope with the second factor, then the flammability of polystyrene foam can no longer be removed.

And using insulation with a flammability class when finishing a wooden roof is already a rather risky decision.

It is also a little more difficult to insulate with polystyrene foam. Since, unlike mineral wool, it needs to be cut very clearly in order to be correctly and securely fixed between the rafters. There are no such problems with cotton wool, because it can deform and shrink to a certain percentage of its volume.

IN Lately Increasingly, foam plastic that has gone through an extrusion process is used to insulate pitched roofs. That is, it was melted in a furnace under high pressure.

This insulation costs more, but has higher performance and a flammability class of G1 (regular polystyrene foam has a flammability class of G2 or even G3).

2.3 Polyurethane foam

In our area, polyurethane foam is rather exotic. But over the past few decades, it has begun to rapidly gain popularity.

This insulation is made from polyurethane foam. It can be produced both in slabs and in the form of liquid foam. It is not recommended to use slab polyurethane foam for roofing; if you consider how much it costs and all its properties, then it will be much more profitable to use mineral wool.

But applying liquid polyurethane foam is a much more interesting and useful process. The fact is that in liquid form polyurethane foam can be filled with frames of any shape. It will evenly fill all the cracks and openings, and without your participation in this.

Agree, it’s much more convenient to work this way, especially if you need to process the structure of a slate roof or sloping roof. Where the frame is extremely uneven.

Plus, polyurethane foam in its finished form does not require thorough hydro- or vapor barrier. And it has a flammability class of NG, that is, it does not burn in fire.

2.4 Insulation technology and its nuances

Now let's turn to insulation technology. In part, if all the rules are followed and the nuances are taken into account, the work can be done independently.

Insulating a roof from the inside with your own hands will largely depend on the type of insulation used. That is why we spent so much time analyzing modern variations.

So, the easiest way to work is when it is necessary to arrange thermal insulation gable roof and do . In this case, you can work with any insulation. If you have to finish a roof with complex shapes, then you will have to tinker with foam plastic.

There can also be problems with mineral wool, but only if you decide to buy rigid slabs, and such slabs are almost never used for internal roof insulation.

With foam plastic, you will have to spend time on very precise adjustment to the frame and the size of the rafters; in case of an error, you will have to cut it off and measure everything again. It’s easier to work with mineral wool, but not much.

But polyurethane foam in liquid form is almost ideal. But it can only be applied with special equipment and with protection. Therefore, you will no longer be able to work on your own. You'll have to turn to the experts.

2.5 Operation algorithm

The technology itself is very simple and consists of creating a kind of insulating cake from waterproofing, thermal insulation and vapor barrier.

On both sides, the cake is closed with a crate and flooring. If you need to work in the attic, then inner part limited to only one crate.

When finishing the attic, boards or any other are stuffed on top of it. finishing coat. Even including plastering.

Stages of work:

We inspect the surface of the roof frame, if necessary, repair the slopes.
We install a waterproofing film.
We lay the insulation between the rafters. If the dimensions of the rafters are not enough, we install another level of the frame (this happens very rarely).
If necessary, we mount the second level of insulation. We lay it with bandaging of the seams between the slabs to reduce the likelihood of the appearance of cold air bridges.
Additionally, we fix the thermal insulation with screws or dowels.
We lay the vapor barrier film.
We stuff the sheathing.
Installing the finish coat.

When working with polyurethane foam, you can completely avoid installing a vapor barrier. And its application always occurs in one step, by filling the frame with foam.

2.6 The process of insulating a roof from the inside with mineral wool (video)

Country living in a private house has ceased to be the prerogative of a single number of citizens. Individual construction housing is rapidly developing, and people have to solve problems with improvement, in particular with insulation. It is quite easy to insulate walls from heat leakage, but properly insulating the roof of a house is much more difficult. However, we can solve the problem - you just need to carefully select the material and competently carry out the thermal insulation work with your own hands.

Depending on the side of the roof on which the insulation is laid, there are two methods of thermal insulation:

from the inside (otherwise called the “solid ceiling principle”);
outside (“rolling ceiling principle”).

Most often, residents have to insulate the top of the house in the first way, since most moves to a new place of residence occur during the warm season. When the first frosts begin, the problem makes itself felt. This is due to the structure of houses - a large number of heat leaves the room not only through doors and windows, but also through the roof. To minimize losses without dismantling the roof, the thermal insulation of the roof is made from inside the house.

Features of the choice of materials

The urgency of the problem has been established; Now you need to choose the right material. The issue of saving money should not be brought to the fore here. It's better to consider three important factors, information about which is usually indicated on the packaging:

thermal conductivity of the insulating material (the value should be minimal; optimal - up to 0.04 W / m ⁰С);
resistance to mechanical and climatic influences, which, in turn, depend on the region of residence;
the weight of the insulation (the heavier it is, the greater the load on the roof elements, and this is undesirable).

To achieve the desired effect, it is recommended to choose a sufficiently soft and elastic material so that it fills the free space between the rafters. You will also need vapor and waterproofing. The best materials To prevent moisture from getting into the insulation, use:

roofing felt;
glassine;
polyethylene film;
special vapor barrier membrane.

It is necessary to take into account the features of the terrain; If there is frequent precipitation, you should choose a denser material to insulate the roof from the inside.

There are several ways to ensure proper quality of thermal insulation. The most common are:

laying glass wool;
internal lining with mineral wool slabs;
installation of polystyrene foam panels;
filling with PPU (polyurethane foam).

The most expensive is the last method of insulation. It is also not recommended to apply polyurethane foam in the cold season, and when foaming the roof with it, ensure sufficient ventilation. If residents still decide to insulate the roof from the inside with their own hands using of this material, you will have to take into account the rapid increase in its volume followed by solidification.

It is much easier to implement any of the first three methods (list above), and the work can be reduced to several stages presented below. This applies to both types of roofs (flat or pitched), however, due to the popularity of the latter, the process will be considered specifically for them.

Preparing the roof for insulation

Direct thermal insulation of the roof with your own hands should be preceded by the following steps:

inspection truss structure, replacing rotten or deformed elements with new ones;
treatment inner surface roofs with an antiseptic to prevent the formation of mold and anti-corrosion liquid to prevent metal parts from rusting;
analysis of the state of water supply, heating, communications, electricity and other networks if they pass under the rafters.

The insulation is selected according to the distance between adjacent rafters. If its width is less than this value, cracks or cold bridges will appear and the effectiveness of thermal insulation will decrease. Because of such an unreliable roof structure, all the work will go down the drain.

Do not work with wet insulation. It should lie in a dry, ventilated area with low humidity for 2-3 days. This is especially true for mineral wool - when interacting with moisture, its insulating properties are reduced by almost half.

Required Tools

In addition to waterproofing and insulation, for comfortable work You need to stock up on the following equipment:

construction stapler;
nails (preferably up to 50 mm long);
stationery/regular knife (for cutting insulator);
fishing line or slats (for fixing the insulation).

If the room under the roof becomes residential, most likely it will be covered with wood or plasterboard and wallpapered. It is advisable to perform the operation 2-3 days after the insulation work, since the insulating material will slightly expand, taking up extra bed. After preparing the necessary things, it’s time to study the question of how to insulate a roof with your own hands and implement your plans.

Sequence of work on interior roof cladding

If the residents of a private house decide to do all the work themselves, it is important for them to adhere to the following sequential steps:

The distance between the rafters is measured. Insulation material cut 1-2 cm wider than measured.
If there is no waterproofing, it must be installed. It should completely envelop the rafters and is attached to them with stapler staples. When fixing roofing felt (or other waterproofing material) in the spans, it is fixed to the sheathing on which the roof lies.
The structure of the rafters and other elements is such that it makes it possible to provide insulation output under the overhang of the upper part of the house. There will be no layer between the insulation and roofing felt (polyethylene, membrane, etc.), so the moisture will be removed in a timely manner.
After installing the waterproofing material along the edges of the rafters at a distance of 3-4 cm from it, nails are driven in 10 cm apart. A cord (fishing line) is stretched between them, creating a small air barrier to drain liquid.
Next, the nails are nailed to the edge of the rafters if the material placed between them is secured with fishing line. When installing batten sheathing, nails are not required.
The insulation is placed in the grooves between the rafters with slight compression. Then it will straighten out, optimally filling the space. It is advisable to make two layers of insulation, and the joints of the first layer should not coincide with the joints of the second.
A fishing line is stretched over the heat-insulating material or a lath is nailed. Between parallel horizontal sections must be at least 30 cm.
A vapor barrier is stapled on top of the insulation. It is laid with an overlap (10-15 cm), and the joints are taped. If the room will be used for living, the inside will need to be finished with chipboards, clapboard, and plasterboard. It is advisable to maintain a gap between the sheathing material and the vapor barrier; To do this, you need to fix the latter not with a stapler, but with strips.

Features of flat roof insulation

One or two device pitched roofs removes more moisture compared to almost horizontal counterparts. For good insulation On the flat top of a residential building, a fill layer is added, which is a mixture of cement, sand and expanded clay. It is located above the waterproofing, that is, it protrudes closest to the roof. The bulk mixture makes the structure heavier, but only similar device“layer cake” guarantees decent thermal insulation of a flat roof.

This instruction provides a comprehensive answer to the question of how to insulate a roof with your own hands quickly and conveniently. The whole process takes a little time, but requires a responsible approach at every stage, especially when choosing material.

Following the presented plan is doubly comfortable - the top floor of the room will be insulated from the inside, and the roof will remain intact. Obviously, even with your own hands you can get a durable warm roof without using the services of repair teams.

Without high-quality thermal insulation at home, it will not be possible to save on heating in winter. Walls and floors are not the only ways through which heat leaves a living space. In addition to them, it is also necessary to insulate the roof.

Internal insulation scheme

A kind of pie is a high-quality insulation of the roof from the inside, consisting in almost all cases of three main layers:

Waterproofing
Thermal insulation
Vapor barrier

However, the basis of the entire structure is the rafter system, which will act as a base link. The easiest way is to lay a thermal insulation layer inside it.

Properly selected materials for each layer of the pie are the basis for high-quality insulation. The market is rich in various products, but you should not pay attention only to cheap options, giving preference to the golden mean.

The main purpose of the waterproofing layer is to protect the insulation from moisture from outside. It accumulates inside it, destroys the structure of the material and renders it unusable. The task of the vapor barrier layer is to prevent rising vapors from passing through.

To protect against wet environments, special membrane or film materials are used. The permeability indicators of the former are better, but their market value is more expensive. Since it will not be possible to ensure complete sealing of the insulation, it is necessary to provide ventilation gaps and seams.

Choosing thermal insulation material

Many manufacturers offer consumers a variety of thermal insulators, each of which has positive and negative sides. Among all performance characteristics Special attention It is customary to pay attention to the following:

Level of moisture absorption - the lower this ability of the materials in question, the more long term their services can be counted on
Thermal conductivity – it should be as low as possible. However, this indicator is relative, since an increase in porosity and importance can significantly worsen it
Low-density insulation materials have much better thermal insulation properties

Video on material selection

You should also pay attention to such characteristics as environmental friendliness, chemical resistance, flammability and frost resistance.

The most widely used methods for insulating roofs from the inside are: mineral wool and glass wool. They have all the necessary characteristics and are relatively easy to use.

Expanded polystyrene is no less popular. In addition to high thermal insulation properties, it practically does not absorb moisture, durable and tough, resistant to high temperatures and open fire. A significant disadvantage is the susceptibility to rodent infestation. That is why it has not become widespread.

Other, less common methods of internal insulation are also possible:

The use of spraying is one of the most expensive methods, which is recommended to be entrusted to a professional craftsman. If you need to insulate a conventional attic, you should choose this method. Material costs will be paid off by performance characteristics
Insulation with liquid compounds (polyurethane foam or foam concrete) is not very popular, as it requires the use of specialized equipment to carry out the work

If thermal insulation of a classic attic space is required, additional insulation is provided above the ceiling (expanded clay, sawdust, sand, etc.).

Let's start insulating the roof with our own hands

The most common case is the insulation of pitched roofs using roll materials. First of all, you need to draw up instructions for yourself, following which you can count on high quality results. Let's consider the case when the roof has not yet been laid.

First you need to go through the attic again and make sure that all the components are in in perfect order. If defects are found (rotting, cracks, etc.), they should be eliminated immediately.

Sometimes various communication systems are laid on the roof: electrical wiring, heating, water supply, etc. They are also subject to thorough inspection and elimination of defects. Only after order has been established can further work begin.

The first step is to apply a waterproofing film to outer surface. In order for it to fulfill its purpose, several rules must be taken into account:

It is necessary to lay the film across, and at the joints, stripes of about a meter are applied, which are glued with tape.
It is necessary to select material for waterproofing only after purchasing a heater so that they match each other in terms of characteristics
Under no circumstances should you pull it tightly over the surface. At sub-zero temperature it will begin to tighten and, as a result, may burst

Having completed work with waterproofing, it is necessary to proceed with the arrangement of the crate. For her, bars treated with antiseptic materials with a size of no more than 25 mm are recommended. Corrosion-resistant self-tapping screws are used for fixation

Roofing materials can be attached directly to the sheathing. Things will be a little different with soft roof. Between it and the wood, it is recommended to place moisture-resistant drywall or chipboard.

The next stage is the laying of heat-insulating material in the gaps between the rafters. It is recommended to adjust the slabs according to the width between the rafter opening, the mats are cut into pieces equal to each other.

The material is laid in such a way that there are no gaps between the elements. It should also not be pressed very tightly against the roof so that there is a ventilation gap.

Another feature is the laying of heat-insulating material not in one, but in two layers. At the same time, they are located relative to each other with an offset so that the through joints close.

Having finished laying the insulation, you can proceed to the next stage - tensioning and fastening the vapor barrier film or membrane. It is recommended to nail it to the rafters with staples. It, unlike waterproofing, is stretched much tighter.

Next, you can proceed to the final stage of insulating the roof from the inside - interior decoration. Stuffed on top of the vapor barrier film wooden frame, to which the desired finishing material will be attached.

Some useful tips

When insulating a roof from the inside, not everything can go as smoothly as it seems at first. In addition, any rafter system has its own characteristics.

We list a number of rules that may be useful when performing roof insulation work:

Particular attention to waterproofing and vapor barrier must be paid when working with mineral insulation. They are most susceptible to the accumulation of moisture inside, causing destructive effects.
Sometimes, for a light roof, the roof truss system is constructed from timber of a small cross-section. In this case, you will have to use a combined method of thermal insulation, placing the material not only between the beams, but also under them
When the step rafter system too large, the insulation is additionally fixed with wire, which is pulled between screws screwed into the rafters
To ensure that the insulation is not tightly located between the rafters, its width must be greater than the similar characteristic of the openings
You should not make too many layers of insulation. For example, for thermal insulation with a thickness of 20 cm, two layers of 10 cm each would be better than four layers of 5 cm each.
The insulation can be placed close to the super diffusion membrane. In all other cases it is necessary to leave a ventilation gap
It is necessary to monitor ventilation gaps, which should not be blocked by thermal insulation material

In custody

Absolutely everyone can make high-quality insulation of the roof from the inside, which will serve for decades, reliably retaining heat and keeping out the cold. However, for those who do not want to waste their time and energy, professionals offer their services. The cost of work can vary between 5-25 USD. e. per square.

Reasons why you will have to insulate your roof in country house, maybe several - you purchased a house with an uninsulated roof, it was simply given to you. But one of the reasons simply “breathes” with nobility of soul - you decided to refuse the services of professional builders and insulate the roof from the inside with your own hands.

Add to your desire to work the ability to be precise in detail, and your roof insulation will go off with a bang.

One thing needs to be understood for sure - it will not be possible to do without preliminary thorough theoretical preparation.

Therefore, we present the result that, regardless of the material used, you will need to strive for (see photo):

Roofing material is the one that takes the blow of bad weather. It can be tiles, metal tiles or, simply, slate.
The sheathing actually refers to the system for creating the roof.
Secondary sheathing, already for attaching the next layer.
Waterproofing panel.
Insulation is the main element of the insulation system.
Vapor barrier panel.
Lathing is often installed after the insulation to further secure it.
Internal lining.

Materials

Among the various types of insulation that can be offered to you to solve the problem of how to insulate a roof from the inside, the following appear:

. This is the most common type of insulation, and if you use basalt-based wool, then it can be said to be recommended. The wide variety of options offered in terms of composition and geometry will allow you to definitely find what you need, which corresponds to the pitch of the main floors of your roof. When purchasing this type of insulation, you only need to ask the seller for a certificate of sanitary safety of the material.

Often, even on inclined planes, no additional fixation of the insulation is required - the main thing is to accurately select its dimensions

Glass wool. This material has been used very widely for quite a long time. But today, due to the emergence of more environmentally friendly materials, glass wool is gradually losing its popularity. In any case, if you decide to use glass wool for insulation, then carry out all the work in special work clothes, which you won’t mind throwing away later. Be sure to cover your face, eyes, and first of all, your hands. You should not use glass wool if allergies are constantly “registered” or sometimes “visiting” in your home.

Polymer materials. Using polymeric materials in the form of expanded polystyrene or polystyrene boards is a very tempting solution, but be careful not to take it hastily. The point is not that these materials are flammable; the worst thing is that when burned, polymers emit a lot of smoke, which is sometimes very dangerous for the body. Therefore, the use of polymers should be classified as extreme, hopeless situations (find out also,).

Expanded clay. This material is well known as an excellent heat insulator, but insulation sloping roof from the inside or inclined is completely inconvenient. After all, expanded clay is a mass of small fired fractions that will simply roll down. It’s possible, but somehow it didn’t catch on, using expanded clay for insulation flat roofs, although it is often used when insulating floors.
