Features and rules for choosing adhesive for polyethylene foam, an overview of popular brands
Penofol consists of 2 layers, thanks to which it retains heat. The material is made on the basis of polyethylene foam and is used in ventilation and air conditioning systems to provide sound insulation, to insulate facades and walls of houses, basements and attics, floors and ceilings . To fix penofol, glue is used more often than liquid nails, due to which the environmentally friendly and fire-resistant material firmly adheres to the surface.
How penofol and isofol are obtained
Light and thin insulation used in construction, the automotive industry and produced in rolls is divided into several types. All types of penofol are made from polyethylene foam, with one or both sides subjected to foil.A composition with a special protected coating is applied to the self-adhesive material.
Isofol is obtained from soft and elastic polyethylene, which adheres to various surfaces, cuts well and serves for a long time. The sheet material has excellent insulating and reflective properties, is easy to attach and has low thermal conductivity.
Advantages of using polyethylene foam
A transparent film made from a synthetic material half a century ago is used as one of the best heat and sound insulators. The presence of closed pores gives expanded polyethylene:
- strength and elasticity;
- sustainability;
- excellent sound insulation.
Insulation several times reduces the external noise indicator, does not rot, rot, mold or mildew. Polyethylene foam is inexpensive, but it ignites on contact with fire. To get rid of this drawback, flame retardants are added to the composition.
How to choose glue for work
When buying a means of fastening a popular insulator, it is necessary to take into account what finish it will be used for, what properties it should have.
Durability of adhesion
Under the influence of intermolecular forces, dissimilar solid particles begin to stick together. The composition of the polyethylene foam mounting agent should have high adhesion.
Thermal range
The glue used to fix penofol is stored in a dry room at 10-25 degrees. If during transport the temperature drops to 5, the product is heated to at least 20 before use.
Toxicity
When installing the insulation, it is not necessary to protect the eyes, skin, respiratory organs, but you should work with glue in a ventilated room, pour the flammable substance away from sources of fire.
Resistant to extreme temperatures and weather conditions
The glue used to fix the insulation on the inner surface of the building or on the outer walls must be resistant to low temperatures, adhere to penofol in the heat and not collapse after rain.
For saunas, baths water-repellent properties
Expanded polyethylene is used not only to insulate living rooms, bedrooms in apartments, offices and warehouses, the material is used for vapor barrier in baths and saunas.
The adhesive used for these purposes should contain substances that repel moisture.
Review of popular solutions
For fixing polystyrene, universal means, one-component substances, mineral mixtures and polymer glue are used, the list of which is constantly updated.

The surface on which the panels are fixed is previously degreased and leveled. The mixture is combined with cold water, consumed in half an hour.
"Akrol"
The adhesive, which contains additives that increase adhesion, ensures a strong connection of the insulation board to glass, metals, concrete, even at high temperatures and humidity. Glue "Acrol" seals small cracks, hides irregularities, is applied to a dry surface in a continuous layer, pressed to the base. The glue does not need to be diluted as it is packaged in pieces and ready to use.
"Neoprene-2136"
In order for polyethylene foam to perform the functions of insulation and insulating material, it can be attached to the wall cleaned and treated with an antiseptic solution with the spray "Neoprene-2136".The glue is rubber-based, contains additives and fillers in the form of silicon dioxide and calcium silicate, provides adhesion in a quarter of an hour. The compound is resistant to acetone, alcohol, aliphatic hydrocarbons.
"Ceresit"
High-adhesion construction glue allows you to fix polypenoids and ceramics even on surfaces prone to shrinkage.
The product made by Henkel, filling the joints, reliably adheres the insulating material to the surface.
Several varieties of Ceresit glue, appreciated for their characteristics, are used to connect the plates inside and outside the building:
- resistance to sub-zero temperatures;
- water-repellent property;
- high adhesion;
- ease of care.
The Ceresit range contains cement which, in contact with a liquid, enters into an alkaline reaction. When working with glue, you need to protect the skin so as not to cause irritation.
"Olfix"
Knayf is suitable for bonding rock wool and expanded polystyrene panels to plaster and brick walls with uneven surfaces. Glue, based on gypsum and additives, is poured with cold water and applied in portions along the center and along the sheet. The board to be glued is pressed against the base and placed in a plane.
Penoplex Quick Fix
For fixing the extruded polystyrene foam panels, an adhesive foam based on plastic polyurethane is used. Penoplex dries in 10 minutes, hardens in a day, suitable for exterior work, internal thermal insulation, provides adhesion to plaster, expanded clay concrete, building stone, wood.

The BF-4 ideally contains products exposed to bending and shock. With the hot exposure method, the parts are bonded together in 40 minutes.With the cold method, the composition is applied in 2 layers with an interval of half an hour.
How to prepare the surface
Before applying the glue, the wall and ceiling must be cleaned of dirt, grease, leveled, dried and, if necessary, treated with sandpaper. Cracks on the concrete surface should be putty.
How to ride
Penofol is glued so that the film side remains inside the part. To strengthen the thermal insulation, an air gap of 20 mm is created. To anchor a panel:
- Glue is applied to the surface, the edges are spread.
- The plates are connected joint to joint.
- When taking the composition leave at least a quarter of a minute.
- Smooth the coating, smooth out the creases.
Insulation is lined with plasterboard, clapboard. Install decorative building materials on the crate.
Binding characteristics
Each surface has its own characteristics.
to concrete
Before applying the glue, the surface must be cleaned, leveled, primed. The composition is coated on the side of the insulation board that is not covered with foil. After a minute, the tile is laid on the surface, pressed to stick.
To metal
To bond styrofoam to aluminum or steel, builders recommend purchasing liquid nails or products that can instantly bond the metal and panel together. Polyurethane-based formulations provide a strong bond. For a small volume, it is convenient to use double-sided tape.
Additional tips and tricks
Before gluing expanded polystyrene on concrete surfaces, they are first cleaned of dust, grease, the gaps are closed and primed. The sheets are bound from bottom to top to avoid the formation of air jams, and it is recommended to apply the glue evenly.
It is not necessary to plaster the joints, since they are filled with putty.
For fastening to the surface of expanded polystyrene, you can not use glue containing acetone, white spirit, gasoline, solvents destroy the structure of the material. If the composition hardens for a long time, it is recommended to press the plates against the plane until the glue hardens.
