About thermal insulation material

Penopelex® – This is the first and most popular brand of thermal insulation from extrusion polystyrene foam. Received since 1998, now in the company-producer (Penopelex SPB LLC) operates 10 factories, two of them abroad. Material in demand in all regions of Russia and other countries. Thanks to the company, the word “Penopeleks” was entrenched in Russian as a conversational synonym for extrusion polystyrene foam. Products manufactured by Penopeles are easy to distinguish from products from other manufacturers on plates and packaging of orange color, which symbolizes heat and environmental friendliness.

Selection of high-quality thermal insulation plates Penoplax® Of all possible options for thermal insulation materials, the advantages of extrusion polystyrene foam, which is said below.


  • High heat shielding properties. Thermal conductivity in the most adverse conditions does not exceed 0.034 W / m ° С. This is significantly lower than other widespread insulation. The smaller heat condition, the better the material keeps heat.
  • Zero water absorption (no more than 0.5% by volume – negligible low value). Provides stability of heat-shielding properties that are practically independent of humidity.
  • High compression strength – at least 10 tons / m2 at 10% linear deformation.
  • Environmental Safety – The material is manufactured from those general-purpose polystyrene stamps that are used in the food and medical industry with their high sanitary and hygienic requirements. Production uses modern foaming technology. Plates do not emit either harmful dust or toxic vapors into the environment, do not contain waste, t. To. In production only primary raw materials.
  • Biostost – The material is not a female fungus, mold, pathogenic bacteria and other malicious microorganisms.
  • Resistance to high and low temperatures, as well as their drops. Polyoplax Plate Application Range®: from -70 to + 75 ° C.
  • Sizes plates (length 1185 mm, width 585 mm), comfortable in loading and unloading and transportation.
  • Optimal geometric configuration with M-shaped edge to minimize direct cold bridges – allows you to securely docile the plates and connect their brass.
  • Convenience Montaja – Due to the unique structure, as well as the combination of low density and high strength of the material, you can easily cut and cut the plates with high accuracy, to give products from Penoplax® Any desired form.

  • All-weather Montaja Due to the wide temperature range of application and moisture resistance.


  • Sensitive to the effects of UV rays. It is not recommended for a long time to leave the layer of external thermal insulation Penoplax® outdoors, the period between the end of thermal insulation works and the beginning of the finishing should be insignificant.
  • Collapsed by organic solvents: gasoline, kerosene, toluene, acetone and t. NS.
  • Gray grounds G3, G4.
  • With increasing temperature, starting with + 75 ° C (see. Temperature range of use), material loses strength.

Required materials and tools

Loggia insulation Penopelex® plates

For the insulation of the loggia, two brands of the plates may be required:

  • Penopelex Comfort® – For sex, as well as walls and ceiling when they finish without the use of plaster-adhesive compositions (on the jargon of construction workers, this method of finishing is called “dry”), for example, trimming by plasterboard.
  • PenopelexWALL® – for walls and ceiling when they finish with the use of plastering and adhesives (on the jargon of construction workers, this method of finishing is called “wet”), for example, plaster or ceramic tiles. Plates of this brand have a milled surface with notches to increase adhesion to plaster-adhesive compositions.

The thickness of the plates for the application region and their quantity is recommended to count on the Penoplex website.RU in the “Calculator” section.

In addition to plates Penopelex®, For the insulation of the loggia, the following materials and tools will be required:

  • Fasteners for fasteners: glue (for heat-insulating plates The manufacturer recommends using the brand glue Penoplex®FastFix®), mounting foam; liquid Nails; Dowel-nails; self-tapping screw; Fasteners with wide hats; Perforator and screwdrut.
  • Tools for cutting and cutting insulating plates
  • Dry mix for creating a cement-sand tie.
  • Parosolation film.
  • Antifungal primer and impregnation against rotting.
  • Bruks, rails, profile for the crate – when insulating under the decoration without the use of plastering and adhesives (see. below).
  • Adhesive tape.
  • Two levels (100 cm and 30 cm).
  • Finishing materials for floor, walls and ceiling, as well as means for mounting them.
  • Means for washing assembly pistols, as well as removal of residuals of unworthy foam and glue from clothing and open parts of the body. The manufacturer recommends a Penoplex organic solvent cleaner®FastFix® in aerosol packaging.

Stages and progress

We divide the process of the insulation of the loggia into three large stages, each of which contains several operations.

Stage 1. Preparatory

Stage 2. Wall insulation and ceiling

Stage 3. Floor insulation

The second and third stages have two options each. Walls and ceiling are insulated under the decoration using or without the use of plastering and adhesive compositions, and the floor – depending on the type of screed: reinforced cement-sand or collected-leaf.

Note that here we do not consider the processes of glazing (necessarily warm, with double or triple glass), as well as gaskets of engineering communications. We believe that these works are made. Wiring must be packed in the corresponding boxes or corrugated pipes from non-combustible material. Double-glazed windows must be protected from contamination or mechanical damage. They can be closed with a conventional polyethylene film. Some specialists recommend to extract double-glazed windows from RAM, but it is not necessary.

one. Preparatory stage

It is to clean and process the surfaces of heat-insulated structures: floor, walls, ceiling.

one.one. Remove all items (in the loggia usually stored a lot of things), dismantle the shelves, old finishing materials (if any), pull the nails, hooks and t. D.

one.2. Fill the mounting foam all the slots and the elevated areas. Give foam dry during the day, then cut off its excess.

one.3. Processing with antifungal composition and impregnation against rotting. Give dry within 6 hours.

2. Wall insulation and ceiling

We consider two options: for finishing with or without the use of plastering and adhesive compositions.

Option of wall insulation and loggia ceiling with decoration without the use of plaster-adhesive compositions (in particular – plasterboard).

2.one. Apply Penoplex glue®FastFix® On the surface of the plates according to the instructions on the cylinder. One cylinder is enough for 6-10 m2 Surface plates.

2.2. Fix the plates of Penopelex Comfort® to the surface of the walls and ceiling. Orthodox and slots in the joints are filled with Penoplex glue®FastFix®.

Note. The decoration of plasterboard can be performed without vapor barrier and guides, with adhesive fixation of sheet material to thermal insulation plates. In this case, the plates of the brand Penopelex applyWALL®, Stage 2.4 is excluded, and steps 2.3 and 2.5 are performed as follows:

2.3. Slide the seams at the joints of thermal insulation stoves using construction adhesive tape.

2.five. Sheets of plasterboard are glued to plates. For this purpose, the manufacturer of thermal insulation recommends applying Penoplax glue-foam®FastFix®. It is necessary to monitor the layer of heat insulation to which the sheet material is glued, was smooth.

2.6. Processing shelves of sheet material.

2.7. Perform an finishing finish.

2.3. Apply the base glue layer on the rough surface of Polyoplax platesWALL®.

2.4. Insert the fiberglass alkaline grid to the base glue layer.

2.five. Put primer.

2.6. Apply decorative plaster or putty.

3. Floor insulation

We consider two options: with cement-sand reinforced and team-leaf tie. The first should have a thickness of at least 40 mm. The second is performed from two layers of GVL, CSP, plywood, or finished floor elements in one layer. Until the adjustment of the screed, technological operations for both options are the same, namely:

3.1 Align the base of the floor, eliminating irregularities more than 5 mm.

3.2 Mount Polyoplax Plates Comfort® on an even base in a checkerboard without fasteners. Depending on the required thickness, you can lay the plates into one or more layers. Where the screed should be tied up to the wall, put the damper ribbon from foamed polyethylene or fragments of Polyoplax plates Comfort® 20 mm thick, sliced ​​in height of the future screed. First, it is necessary, first, for sealing when shying a screed, secondly, for sound insulation, so that noise from falling any items to the floor of the loggia is not transferred to neighbors on the floor and below.

Options for insulation of floor loggia with reinforced cement-sand tie (CPS), further stages

3.3. Gift joints plates Polyoplax Comfort® aluminum-based adhesive tape or plastic film. This will prevent possible leakage of cement “milk” through the joints of thermal insulation.

3.4. Install the reinforcement grid on plastic locks (in the form of “chairs”). In this case, a mesh with cells 100×100 mm and a 3-4 mm reinforcement diameter.

3.five. Poured the CPS.

3.6. Shut down the finishing layer of the floor – materials that do not require the use of plastering and adhesives (laminate, parquet and t. NS.).

3.3. Located sheets of GVL, CSP or plywood in two layers in a checkerboard on top of the plates of Penopelex Comfort®, either perform the installation of finished elements in one layer. Layers of sheets are fixed with each other short screws. Do not allow the entry of self-insulation into the body of the insulating plate.

3.4. Shut down the finishing layer of the floor – materials that do not require the use of plastering and adhesives (laminate, parquet and t. NS.).

If the loggia is provided for “warm floor”, then it should be borne in mind that there is a lot of legislative restrictions for the installation of water heating systems in the apartment. Electric cable floor mounted on a screed after its installation or fill.

The insulation of the loggia is a time-consuming multistage process. However, as a result, you can create a comfortable additional space (small room or relaxation corner), or even expand the kitchen or room by dismantling part of the wall between the room and the loggia.
