Insulation with penoplex

Navigating pages

Few owners consider that their property should be warm and comfortable come wintertime during the warm months. The most important thing is to insulate a home or apartment both inside and out. Save money because it’s not only warm but also improves sound insulation.

Using penoplex for wall insulation is the most popular way to create a cozy space.

While there are many positive aspects to this material, there are also some negative ones. You can quickly save money on bills and have warmth in your home with an easy and quick installation that produces almost no dust or debris.

Whether a wall is inside or outside the home, using Penoplex for insulation offers a practical solution to increase comfort and energy efficiency. Penoplex is a kind of extruded polystyrene foam that is well-known for its moisture resistance, lightweight design, and superior thermal insulation capabilities. Penoplex, when applied externally, protects against extreme weather conditions and aids in maintaining the building’s thermal envelope. It can be applied internally to improve insulation without changing the external appearance. A clean, dry surface and appropriate installation are essential for effective insulation in order to prevent thermal bridges and maximize efficiency. Penoplex provides a flexible and long-lasting solution for adding insulation to newly constructed homes or retrofitting older homes.

Advantages and disadvantages

Both the interior and exterior of buildings are insulated with expanded polystyrene. When it is not possible to work outside, installation is done inside. Partial insulation is also done inside, on a wall facing the north and on a balcony. It is frequently used because of its benefits.

1. The material is lightweight – easy to work with.
2. Low thermal conductivity. The thermal conductivity index is maintained in various conditions (high humidity).
3. Practically does not absorb water.
4. Durability – withstands compressive loads.
5. Service life of 50 years.
6. Soundproof.
7. Temperature range from -100 0C to +75 0C.

Penoplex is not "sharpened" by rodents and does not rot.

One drawback is the low level of adherence. Thus, the back of the polystyrene foam is cleaned before an adhesive solution is applied.

The second drawback is that when it burns, it releases harsh smoke.

The material is used for wall insulation both indoors and outdoors, even with buildings that have high relative humidity.

Features

Penoplex is used to insulate houses both inside and outside because of its benefits. The material’s features include its resistance to rot, waterproofness, and extended warranty. Soundproofing is a crucial point. As a result of the walls being insulated, the home will become cozy and comfortable by becoming warm and quiet.

Can it be replaced with polystyrene foam

Because extruded polystyrene foam has a denser structure than other foams, experts advise using it as insulation. As a result, cold air cannot enter the space. It does not degrade as rapidly as polystyrene foam does.

The installation technique is another benefit of using polystyrene foam for insulation. It is imperative that the work be completed accurately and in accordance with the masters’ advice. If not, the insulation will be useless since cold air and outside noise will enter the space.

Penoplex is installed on various surfaces:

• wooden base;
• brickwork (the material is not destroyed by the released alkali);
• concrete wall;
• aerated concrete, foam block.

Install yourself only after carefully reading the detailed instructions and nuances.

Outside

Penoplex is typically used outdoors to insulate a private home’s facade. This keeps the heat in the house, and there are no mold traces or wet walls. After all, the dew point changes when walls are only insulated internally. There’s mold and moisture. The house starts to feel uneasy. In addition, the structure itself deteriorates because of the ongoing dampness.

Penoplex can be mounted externally in two ways:

1. On glue. The use of certain brands of glue maintains the durability and functionality of the insulation. The stoves for strength are fixed with dowel-zontics.
2. "Ventilated facade" – creating a sheathing from metal profiles or wooden slats. Insulation is placed in the resulting cells, and the facing material is mounted on the sheathing itself.

Using expanded polystyrene to finish a building’s facade allows for the creation of unique and modern design elements. Penoplex is designed to stand out from other homes through the use of decorative plaster, mosaics, and other materials.

Inside

Penoplex is used inside the premises if it is not possible to insulate the exterior walls (the upper stories of apartment buildings) or if it is required to insulate the balcony. This situation has both benefits and drawbacks:

1. If the insulation is installed incorrectly, condensation will appear, which will lead to negative consequences. Mold will appear where the material touches the wall.
2. When installing the material, the usable area of ​​the room decreases.

1. All work on insulation can be done with your own hands, without involving a brigade of masters.
2. Correctly fixed penoplex will keep the room warm and quiet.
3. The material levels the walls.
4. It is often laid under plasterboard structures.

Making a lathing is only required if plasterboard cladding is not available for the installation of polystyrene foam indoors.

Select insulation that has edges that are tongue and grooved. This makes it possible to install butt to butt. The most common grade boards are PPS 25-RG-B.

Types

On the construction market, penoplex comes in a variety of forms. Where the material is used is indicated by the name.

1. "Roofing". Water-resistant type, density 28-33 kg/m3. This type is used to insulate flat roofs. And they also insulate attics. Due to the lightness of the material, the structure does not bear additional load.
2. "Wall". Used for external and internal insulation of the building. Density 25-32 kg/m3. It is also used for insulation and soundproofing of partitions.
3. "Fundament". 29-35 kg / m3. The peculiarity of this brand is its water resistance. They are used to insulate the foundations of houses, basements. They are used for thermal insulation of septic tanks that have a recess.
4. "Comfort". 25-35 kg/m3. Insulation of balconies, loggias, walls inside the apartment. They are used to install the material in baths and saunas.
5. "Basis". Technical characteristics are the same as those of the "Comfort" brand, but it is more rigid and can withstand a greater load. They use a type of penoplex for insulating various surfaces that bear loads (floor insulation). It is also used in industrial construction.
6. "GEO". Alternative to "Fundament". They are used in industrial and civil construction work. Floor and foundation cladding.
7. "Pitched roof". Material thickness 10-15 cm. They are used to insulate single- and double-pitched roofs.
8. "Facade". Thickness 2-10 cm. They are used to insulate building facades. It has a milled surface for better adhesion to the base.
9. "Penoplex-45". 35-47 kg / m3. It is used as a protective layer against low temperatures of different types of road surfaces (garden paths). And also for roofing.

Additionally, marking is used to divide the insulating material. They all indicate different densities.

Wall “pie”

Penoplex walls can be insulated in a variety of methods. a typical example of a "wet facade." Mixtures and compositions made with water are included in this method. Moreover, apply primer and a reinforcing mesh. The end effect is a multi-layered insulated wall that raises the dew point but blocks the passage of cold air.

It matters that each layer be applied in a specific order:

1. The adhesive composition is prepared on the basis of water and a dry mixture. Penoplex is mounted on it.
2. Penoplex boards – insulate and soundproof the building from the outside.
3. Reinforcing mesh made of fiberglass – is a strong connecting element. It promotes better bonding with the surface, and also does not allow cracks.
4. Primer. Neutralizes, protects, promotes better adhesion.
5. Facing material is a decorative element. And also protects the insulation from external factors.

The insulating boards are firmly fixed to one another. The next layer of the "pie" cannot be applied until the glue has completely dried.

How to calculate the required thickness so that the walls are not cold

You must know the material from which the walls are constructed, their thickness, and the specifications of the finishing coating in order to compute the thickness of the thermal insulation material.

It is necessary to compute the heat resistance. The table displays SNiP data for each region in Russia. You must remember that the pie’s layers have varying degrees of thermal resistance. To get one figure, all of the word indicators are added together.

P = R / K, where R is the thickness of one pie layer and K is the thermal conductivity, is the formula used to calculate the thermal conductivity coefficient.

Staging of work

Different techniques are used for wall insulation, depending on where the insulation is to be installed. For labor in an outdoor setting, there is:

• "wet facade";
• "curtain wall".

Inside insulation can be achieved using the following techniques:

• on glue;
• creation of lathing.

Every technique has a set of steps that must be followed; if these are not followed, moisture will start to appear.

Surface requirements

A wall must be prepped before using penoplex to insulate it. In essence, a smooth surface is what is sold with the insulation. There is no adhesion and the adhesive mixture does not lie on the back side. You must process the insulation’s reverse side in order to do this:

• go in one direction with a needle roller;
• wipe the surface with sandpaper – roughness will appear;
• go with a milling cutter (if available).

The back side will become rough after completing one of the specified tasks; this encourages the adhesive mixture to adhere better to the wall.

Preparing the walls

Penoplex installation requires surface preparation, which entails:

1. Align it – remove excess mortar, protruding pins, dust, cobwebs.
2. Peeling plaster and old whitewash are removed from the walls of a private house.
3. If there are traces of dampness, stains, you need to dry the wall, then apply an antiseptic composition (the usual treatment with diluted bleach will do).
4. Treat with a primer 2 times. The second layer is applied only after the first one has completely dried.

No signs of rot should be seen on wooden walls. This part needs to be replaced if any such are discovered.

Is a vapor barrier needed

A vapor barrier is used, depending on where the thermal insulation material is being applied.

1. Outside. This should be done in rare cases. If the house is located in a damp area, in a lowland, near water pits. And also a vapor barrier is mounted outside when insulating a bathhouse, sauna. In most cases, vapor barrier is not carried out. Penoplex provides the necessary protection (water-repellent property).
2. Inside. A vapor barrier layer is a mandatory layer if the walls are not insulated from the outside. The structure has a shift in the dew point. Condensation will protrude into the room from above the insulation. This will lead to constant dampness, destruction of the wall, the appearance of fungi.

Another factor is the material used to build the walls. A vapor barrier layer is required for structures made of concrete or brick, but it is not required for walls made of wood.

Lathing

You will need 50×50 mm wooden slats to make a frame base. In this instance, the width of the plate and the rail should match. The lower slat should first be screwed into place horizontally.

Mount vertical slats from it using a step that corresponds to the plate’s size. Between the slats, the insulation should cling tightly. The second horizontal slat for the second row of the penoplex should then be fastened. Onward, to the summit. Sometimes wooden beams are replaced with metal profiles.

Methods of fastening with glue

Penoplex plates can be adhered to using a variety of materials.

1. Mastic for gluing extruded polystyrene foam boards. Using a bitumen-polymer composition is an economical way to fix the insulation on the wall. Mastic is used in buildings with high humidity.
2. Adhesive dry mixes. The basis of these materials is cement. The solution must be made according to the instructions on the package. Apply the solution with a notched trowel over the entire surface of the board and fix it to the wall. For strength, additional fixation with dowels is required.
3. Foam adhesive. It has good adhesion. The work is carried out quickly and without debris, dust. Foam is applied from a gun to the boards, fixed to the wall.
4. "Liquid nails". Used when insulating a small area.

The mushroom-shaped dowels need to be added to the penoplex boards after choosing and gluing them.

Service life

Penoplex can lie for an indefinite amount of time when it is unpacked and complies with all storage and transportation regulations.

There is a 50-year warranty on the insulation after proper installation. The installed insulation has a 40-year shelf life if the building is damp (a bathhouse, the house is in a lowland, in an area with constant moisture).

Penoplex is a type of thermal insulation that is used for foundation, roofs, walls, and ceilings. It almost entirely lacks drawbacks and offers a lot of benefits. The material has markings and is separated into types. Consequently, selecting penoplex for insulation won’t be challenging. Installation can be done in a few different ways.

The interior space will be comfortable and warm once all the work is finished.

Method	Description
Interior Insulation	Install Penoplex panels directly onto interior walls, then cover with drywall or plaster. Ideal for rooms where exterior insulation isn"t possible.
Exterior Insulation	Attach Penoplex to the outside of the walls, followed by a protective layer like siding or stucco. This method improves the thermal envelope.
Vapor Barrier	Ensure a proper vapor barrier is installed to prevent moisture buildup, which can damage insulation and walls.
Adhesive and Fastening	Use appropriate adhesives and mechanical fasteners to secure the Penoplex panels firmly in place.

Using Penoplex as exterior or interior wall insulation is a workable way to increase a home’s energy efficiency. Every approach has a unique set of benefits and things to think about. By reducing thermal bridging and creating a seamless thermal barrier, insulation from the outside protects the structure from weather variations. This approach maximizes the building’s durability while preserving interior space and aesthetics.

Conversely, Penoplex interior insulation works well in structures where making exterior modifications is not feasible or desired. In order to prevent condensation and reduce the amount of interior space lost, this method necessitates careful planning and moisture management. It is essential to install properly to avoid problems like heat loss and the growth of mold.

Choosing premium insulation materials that satisfy particular standards for fire safety, moisture resistance, and thermal resistance is crucial, regardless of the approach taken. Adherence to building codes and standards along with appropriate installation techniques are crucial for guaranteeing the longevity and efficacy of the insulation. Penoplex insulation can greatly improve any home’s comfort and energy efficiency with careful thought and preparation.
