Warming the foundation with penoplex by yourself: instructions

One of the most common methods of thermal insulation of the foundation today is the use of a penoplex, which is a polymeric material with a closed cell structure. At 98% it consists of air, which, as is known, is the best heat insulator. Working with the material is quite simple because of its light weight.

Why choose penoplex

This insulation for the foundation has a low water absorption, which is 0.5% of the volume during the lifetime. Closed cells are filled with air, which acts as an excellent heat insulator. Due to moisture-repellent characteristics, the material retains its properties in arbitrarily difficult conditions, it is not subject to destruction when the internal moisture freezes. If you want to make the foundation insulation of the foam with your hands, you will have to purchase the material, which is produced in the form of slabs of different thickness. Products may have mounting grooves that allow the use of thermal insulation with maximum efficiency. Strengthen it can be quickly, eliminating the formation of bridges of cold, seams and gaps.

Basic methods of warming the base of the house with penokleksom

If you decide to apply the described insulation for the foundation, then you can take one of the existing technologies as the basis of the works. Thus, the insulation can be vertical, thus protecting not only the foundation itself, but also the base. Such manipulations, as a rule, are carried out from the outside of the building, the space inside the house and the foundation wall gets under protection, which considerably increases the service life of the building.

Penoplex, whose thickness is usually 50-100 mm, is installed on the prepared surface with a polymer-based adhesive solution or cement. When installing the material in the basement of the slab, it will be necessary to fix it with special dowels. Horizontal thermal insulation of a shallow bank of the basement implies the protection of structures from freezing and from the impact of the tangential forces of frost heaving. To conduct work, the slab will need to be laid under the foundation of the foundation.

If you decide to make the basement insulation with foam penis by your own hands, then the technology can provide for the formation of a blind area around the house, which is supplemented by the described thermal insulation. This method is indispensable for the protection of buildings from the deformation forces of frost heaving. Technology is especially important in heavily soils. Initially, it will be necessary to prepare a pillow on which the slabs of penoplex are stacked, only after it is necessary to start forming a concrete blind area.

Recommendations for vertical thermal insulation

The foundation can be warmed with foam by hand using the method of vertical thermal insulation. This method is universal, since it can be used on a building under construction and on a building already built. In the latter case, it is necessary to dig out the base to the depth of occurrence. Initially, the foundation is cleaned of soil debris, various kinds of contaminants and dust. If the surface has irregularities, then it can be leveled with cement mortar.

At the next stage, a coating of waterproofing with bitumen or polymeric mastics on a water basis is carried out. From the composition on the basis of solvents it is worth noting, since the foam from contact with them can collapse. It will be necessary to purchase glue for expanded polystyrene, which is bred according to the instructions. It should be well mixed and left to ripen. Next, the master proceeds to the marking of the foundation, on the surface of which the lower line for laying the plates should be designated. If the structure has irregularities, then the insulation can go deeper than the level of the sole, which, however, does not negatively affect the final effect.

Methods of work

If you decide to make the basement insulated with penoplex by yourself, then the next step is to apply glue to the insulation in several places. In the presence of an absolutely flat surface, the composition can be evenly leveled.

Further, a 50-mm thick penoplex is pressed against the foundation, and then leveled out if necessary. The next element is fixed using the mounting slot. Sometimes it is required to install a foam pen in several layers, while the components of the thermal insulation system must be staggered so that the second layer overlaps the seam of the previous one. This will achieve a positive effect. The second layer is fixed to the same glue, and the technology is not different.

Advice from a specialist

Quite often, recently, the basement has been insulated with foam foam. The technology of carrying out these works must be studied by every master who intends to deal with these manipulations. In the underground part of the base, an additional fixation is not required when laying a penoplex, since when it is filled it will be sufficiently tightly pressed with soil. In the plinth area the foam is additionally fastened with special dowel-nails. They have a wide plastic bonnet, which allows you to hold the material on the wall without rising above its surface.

In the plates should be made through holes, which should go to the concrete for 4 centimeters. After that, you can start installing the fasteners. The length of the drill should be matched to the thickness of the material. If you make the basement insulation with foam, the technology of which is described in the article, then you can apply tile glue or plaster to the surface to decorate the plinth, additionally reinforce the layers with a grid.

Thermal insulation plate foundation

If the building is installed on a slab or a strip foundation, you can use for the work Penoplex, whose thickness is 5-10 centimeters. Initially, it is necessary to mark the site for the foundation, and after removing the top layer of the soil, taking into account the construction project. When taking out the soil, try to make the bottom as level as possible, for this, the last 30 centimeters are best removed manually. The prepared platform is well trampled, and then filled with sand, which must also be compacted.

Before you insulate the foundation plate type, you must perform a temporary formwork, and then prepare a concrete base. The next step is to fill the solution with a thin layer, the formation is not required. As soon as the concrete foundation has solidified, foamfoam plates are laid on it, the mounting grooves in which do not form any gaps. Polyethylene film is laid on penokleks, joints of which should be glued with adhesive tape. With the help of it you will be able to create a layer of waterproofing, which will prevent the flow of concrete through the plates of the heater.

What you need to pay attention to

To carry out this work, you can use a 50-mm thickness foam pen, this will be enough for regions with a not too harsh climate. After carrying out all the above-described works, it is possible to form the formwork, laying the reinforcement and the bay slab foundation. Once the solution has solidified, the formwork is removed, and the side walls are additionally thermally insulated with the same material. If we are talking about a shallow banded foundation, then work should be carried out using a similar technology.

Thermal insulation of the foundation by the method of thermal insulation of the ground

If you are thinking about the question of how to insulate the foundation, you can choose a technique that provides thermal insulation of the soil. This not only reduces the estimated depth of foundation, but also reduces construction costs. When carrying out the work it is necessary to equip the insulated blind area. Once the vertical external thermal insulation has been completed, it is necessary to backfill with gravel and sand 15 centimeters below ground level.

Next, proceed to form the formwork from the boards with a deviation from the wall of a distance equal to a meter. The height of this construction should be about 30 centimeters. Penoplex, which will be installed a little later, is purchased in advance. At the next stage, the bottom of the blind area must be tamped and leveled. Now you can start laying the plates of thermal insulation around the perimeter of the base. On the heater is laid polyethylene film with an overlap on the plinth, after that you can pour concrete into the formwork. Its surface is leveled to form a slight slope to the outside. After solidification of the solution, the formwork can be removed, and the blind area should be ennobled with decorative stone or paving slabs.

Cost

Penoplex, whose cost is 1580 rubles., Shipped in separate packages. For example, the consumer has to pay the mentioned price for 5.76 square meters of material, which is 0.288 cubic meters, or 8 plates.
