Greetings! In articles about insulation, the use of penofol is constantly recommended, but I had a question, how to glue penofol to concrete, for example, if I use a non-self-adhesive option? Thank you.
Hello. We will try to answer your question.
Penofol is an energy-saving material with a layered structure. It combines the properties of polyethylene foam and thin aluminum foil. The material is characterized by lightness and small thickness, and therefore is often used on various objects (including on the balcony) for insulation, tightness, thermal, noise, steam and waterproofing. However, to ensure high-quality protection, penofol is not enough to lean against an insulated surface - you will need a special glue for penofol.
Features of adhesive installation of penofol
Glue for foam foil allows you to quickly complete work on the insulation of surfaces. Besides, adhesive method installation is easy to implement and low-cost, since it does not require any special skills or specialized tools.
Usually, when choosing gluing as a method of mounting insulating surfaces, it is necessary to take into account the bearing capacity of the adhesive layer - but when using penofol, this fact will not be decisive, since the material is incredibly light.
Rules for preparing surfaces before gluing
The right glue for penofol is not a guarantee of successful work. To ensure the solidity of the connection, the main thing is that the surfaces to be glued are prepared. On them, without fail, eliminate all defects, chips, bumps, cracks, as well as dust.
Important: Surfaces made of metal, concrete or wood can be additionally primed for better adhesion of the layers.
One of essential conditions quality result - evenness and cleanliness of the surface. So, concrete floors and walls are leveled, cracks are eliminated on them, and metal elements are treated with an anti-corrosion coating.
What can be used as glue for penofol?
Glue for penofol can be special or universal. For these purposes, professionals also allow the use liquid nails, double-sided tape, thin layer polyurethane foam. The choice of type of adhesive depends on the purpose of the surface, and on its further design.
It is very important here that the characteristics of the adhesive composition correspond to the performance of the insulation:
- the ability to withstand operating temperatures in the range of +100 ... -60 ° C;
- permission for indoor use;
- biological non-toxicity;
- adhesion resistance.
If the insulation is carried out outside, on the facade, then the adhesive composition must necessarily be resistant to water vapor and water. Requirements for non-toxicity are also mandatory, because the balcony belongs to residential premises. Therefore, the adhesive for foil foam foam must certainly have certificates of hygienic safety.
How to glue penofol correctly
In order to correctly glue penofol, you need to apply the selected adhesive composition on the side of the material that is not protected by foil. It is important to apply the glue in an even thin layer and so that all areas of the insulation are smeared, without gaps.
When smearing, special influence is given to the edges of the panel so that the penofol does not begin to peel off during operation. In order to fix the insulation, the material must be held for 5-60 seconds so that the glue applied to it dries slightly. This will ensure the best adhesion of the composition. Then the prepared canvas is pressed against the surface to be glued, held and very carefully smoothed - until it is completely fixed.
If the penofol is fixed in pieces, between which there are seams, then these same seams are additionally glued.

How and what to glue.
Usually, the balcony is first insulated with foam boards, on which foil polyethylene is glued.
To do this, you can use the following glue:
- QUICK-BOND
- 88-NP
- Akrol pin
- spray Neoprene 2136
Joints are glued or overlapped.
You can glue the foam to the foam or to another surface with the following glue:
- CEREZIT ST83
- ANSERGLOB BCX 39
- AQUALIT SK-106 P (polymer-cement mixture)
- MASTER SUPER
- POLYMIN P-20
- STOLIT PC and TYTAN STYRO 753 O2 (aerosol polyurethane)
How to glue foam polyethylene to the wall
For example, to insulate a home, you need to glue the screen behind the battery.
cut out right size foil. Penofol with polished aluminum foil 3-5 mm is usually used.
The screen can be fixed with double-sided tape or glued.

Today, it is the most popular adhesive on the market due to its versatility and wide application. It retains its properties in the range from -30C to +90C, it is used both in everyday life and on an industrial scale.
For its correct use, carefully study the instructions for using the adhesive, it has a large number of varieties.
For a large amount of work, there is glue in packages of 25 kg.
Such as for example:
- adhesive mixture "Facade"
- BOLARS
When building your house, when insulating an apartment, whether it is insulation of a loggia or interior spaces, polyethylene foam is widely used today. It is also (only in a different form) used for insulation sewer pipes or water pipes.
Well-known names such as penofol, penofom, energyflex, isofol, stizol, alufom, faralon ... - these and other materials are the same polyethylene foam that can be made in various forms (rolls, mats, tubes, plates) and with different types lamination (for example, foil or lavsan).
This material is used not only for insulation, but also for sound insulation.
In addition to other advantages of polyethylene, there is also such a property as inertness, i.e. the material does not react with other substances.
On the one hand, this is very good, because. provides safety for humans and durability during operation. But, on the other hand, this causes difficulties during installation - after all, high inertness is accompanied by low adhesion (adhesion).
Therefore, most often foamed polyethylene is mounted either using different options adhesive tape, or simply nailing it to the surface, either with a stapler, or with the help of slats or bars.
Sometimes these methods will not work or will be difficult. So, when mounted on concrete wall it would be better to glue the same penofol, and not nail it with the help of bars and, moreover, do not try to do it with a stapler.
For gluing together and mounting polyethylene foam on the surface, it is worth using special adhesives. Some try to use universal adhesives (such as Moment) and write that they succeed. But a more reliable result can be obtained with the help of adhesives designed specifically for polyethylene.
Especially for foamed rubber and polyethylene foam products
One of the options recommended on the market is 152 I-1 Kleyberg glue from the domestic company Ecoline. It is specially designed for the installation of thermal insulation products made of foamed rubber and foamed polyethylene, it is made from polychloroprene rubber.
Although, according to the manufacturer, the scope of this adhesive is not limited to these materials. It also has high adhesion to steel. Since it is made on the basis of rubber, it is also used for gluing rubber products or for gluing other materials to rubber. In general, if you read the manufacturer's materials, then glue in general can be extremely useful both in construction or repair, and in everyday life, because. in addition to all of the above, it is suitable for gluing a bunch of other materials: laminate, linoleum, carpet, chipboard, fiberboard, cardboard ... it’s not at all clear that this Kleyberg 152 does not glue?
About the operating conditions. The glue is frost-resistant, not afraid of heat (up to 100 degrees it retains its properties), resistant to water, acids, gasoline, oils. All this makes it possible to use it during the installation of thermal insulation made of foamed polyethylene both inside and outside the premises, including industrial premises (workshops, garages, stations, etc.).
By the way, those who are going to arrange heat or sound insulation from foamed polyethylene should take into account that it is gluing that allows you to achieve the integrity of the insulation, without cracks and without holes in the material. What can not be avoided if you use bars, slats, a stapler or something similar.
Modern heaters such as penofol need high-quality fastening. Penofol - polyethylene in a foamed state, foil covers it on top. Regardless of the type finishing material: rolled or sheet, a special adhesive composition is used as a fastener. It allows you to save technical properties material at a high level.
Using special glue
When choosing an adhesive composition for penofol, it is worth considering the type of surface to which it will be attached. The foil coating does not let in a draft, heat. To save heat energy in the building, penofol is attached with inside for a heater. The airspace should be 1 cm. Penofol must be fixed with an air gap.
Styrofoam 5-10 cm wide is used as a heater. Sheets must be glued tightly to a special adhesive composition suitable for foam. Additional fixation is provided by plastic umbrellas. A mesh is attached on top.
Advantages
The use of glue for fixing penofol has the following advantages:
- fast;
- economically;
- you do not need to have special skills;
- no special tools required;
- holds penofol well, due to its lightness;
- not susceptible to moisture;
- glue on natural basis has high efficiency.
Adhesive Requirements
The substance for gluing insulation to concrete must have the following features:
- have high level water resistance and connection with the base;
- not affect the base material destructively;
- do not respond to environment and weather;
- be resistant to temperature changes;
- have antibacterial qualities;
- keep your qualities long time.
So that the material can be well glued, solvents are one of the components of the adhesive substance. Choosing a means for fixing insulation, you need to rely on the type of surface. For each material, a certain adhesive composition is suitable. So, if you need to glue the bath with penofol, heat-resistant glue is chosen for the sauna. Each adhesive composition that is used when performing interior work must have a certificate confirming its safety.
Surface preparation before gluing
Prime the concrete before gluing. It is necessary to prepare the surface correctly for gluing so that the connection is uniform and monolithic. Initially, irregularities and defects are eliminated, cracks are covered, chips are leveled. To improve the adhesion of concrete and foil insulation, the base is primed. Concrete must be smooth, cleaned, protruding metal parts - treated with an anti-corrosion agent.
How to glue?
If the insulation is self-adhesive, it is easy to stick it. Using penofol. the usual adhesive composition is applied to the side without foil in an even layer, thinly, evenly over the entire surface. The edges need to be impregnated with glue more carefully so that during operation the insulation does not begin to lag behind.
The insulation is kept for 10 - 50 seconds so that the adhesive composition has time to grab. So it better connects to the surface. Then the penofol is pressed against the concrete, smoothed, evenly distributed until completely fixed. The seams need to be additionally glued.
Producer examples
Choice adhesive composition, allowing you to connect the insulation with concrete surface. big enough.
At home, vapor and waterproofing can be carried out with ordinary foamed polypropylene (polyethylene). Polypropylene insulation, although primitive, is highly effective, allowing you to save on the purchase of more expensive counterparts.
But polyethylene alone cannot be dispensed with, since glue for polyethylene is required for its use. In more rare cases, other adhesive-based mixtures are also suitable. They are needed for fixing polyethylene (the so-called gluing of polyethylene) on the surface of thermal insulation or any other building structure.
And among the many different adhesive-based mixtures, it is necessary to choose the most optimal and effective one.
Specialists in order to glue polyethylene on thermal insulation recommend using a specialized adhesive-based mixture "Easy-Mix PE-PP".
1 Product information
WEICON's Easy-Mix PE-PP Adhesive Mix is a two-component material for fixing polyethylene without necessary structures, made on the basis of methyl acrylate and adhesive basis.
The chemical structure of this adhesive-based mixture has extremely high adhesion values of the so-called "low-energy plastics and plastics".
This foam adhesive can be used not only for polyethylene, but also for materials such as:
- Rigid PVC (polyvinyl chloride);
- RMMA (along with it is recommended).
In the modern world, polyethylene foam, due to its technical features, since plasticity, elasticity, ultimate strength and chemical resistance, are used everywhere in industrial area and life.
However, interaction with polyethylene is traditionally carried out preliminary preparations its surface. For example, such as:
- Mechanical processing by grinding or sandblasting;
- Chemical treatment (most often fluorination);
- Physical treatment (heat treatment by fire is used).
However, Easy-Mix PE-PP foam completely eliminates the need for such work. With it, gluing polyethylene is possible without preliminary preparations.
The “primer” device, which is in this glue, activates the surfaces, thereby completely changing their structure, after which the gluing of polyethylene is very effective, and the strength of the connection is simply amazing.
The Easy-Mix PE-PP device can be used both for domestic construction work (as a rule, it is thermal insulation), and for use on conveyors and various assembly plants.
