The insulation PENOPLEX: technology outer and inner sheathing

The heating prices are rising, forcing private landlords to find ways to save. A good way out — the insulation PENOPLEX. The technology is not particularly complicated. It can be handled, with the minimum skills in the construction business.

The second name of the material — extruded polystyrene. Get it by foaming of the foam and pushing it through the extruder. When ready, the mass will evaporate the gas, it will be a lot of small, evenly spaced voids. The result is a lightweight and durable material, 95% of which is from the air. Pack of eight 100-mm plates weigh about 15 kg.

There are several varieties of foam polystyrene. And the title clearly indicates its scope. For insulating concrete walls and taken “PENOPLEX Wall.” Note that at a plate 100 mm thick, the heat capacity is the same as single brick. Even polystyrene is resistant to alkalis and acids, so it can be plastered and painted with water-based solutions.

Preparatory work

First you have to scrape from the wall of the old loose paint, Wallpaper, plaster — everything is poorly kept. If the old paint is firmly coupled with the surface and have not lost strength, you can leave it. Align putty all hillocks and hollows, otherwise the plate is poorly glued, and then will break down from depression. Margin of error no more than 1.5 cm per linear meter.

A useful tip! If there is internal insulation of walls with foam polystyrene, and the technology of the process requires impregnation of the surfaces of antifungal agent deep penetration. If the leaves are sewn on the outside, the fungicide treated the bottom of the wall where the dampness growing moss.

Exposed walls must be primed. All metal construction, which can be covered with insulation, painted or covered with anti-corrosive composition. Before starting work, score brackets for mounting of drainages, satellite antennas, junction boxes, cable channels, air conditioning. Smooth foam polystyrene plates rolled with the spiked roller.

Materials for mounting plates

Separate question — what glue polystyrene. Many use foam. It’s convenient — no need to dissolve the adhesive, spread sheet, to withstand a certain time. What “print” is suitable for thermal insulation of walls with foam polystyrene?

When selecting an adhesive it is important to ensure that its composition is suitable for installation of PENOPLEX

After all, technology should be reliable and safe:

  • in the composition of the foam is unacceptable presence of toluene. This substance destroys and polystyrene, and human health;
  • if the area of the insulation is large, it is better to use a professional foam with a nail gun;
  • a better grip will give one-component polyurethane foam.

This method is good because you can supinity all the bumps and gaps, which are inevitable when cutting boards. The joints closed ordinary adhesive tape. The only negative is that the price of the foam can boost the cost of warming.

Much cheaper dry adhesive mixture. They are divided into groups according to the type of binder component:

  • cement or gypsum (mineral) — Cerezyme, Sarmat, Talala;
  • polyurethane — Titanium for foam polystyrene, Somely;
  • waterproofing — bitumen mastic, Uniflex;
  • on mixed polymers of Amphicol.

The mixture is Packed in bags of 5-50 kg. Desyatiletnego bag enough to trim 10-15 square meter of the wall, depending on the composition of the adhesive.

Attention! Undeveloped glue cannot be diluted and stir again, and add in a fresh batch. Its properties irrevocably lost.

Sometimes before placing the plates on the exterior walls set the profile frame. This is justified if later on it will be attached to the material for finishing (drywall, siding, house, block house). The crate is usually made from aluminum elements.

Where the climate allows, you can fill a wooden beam. But in temperate latitudes too wide amplitude of day and night temperatures, and precipitation enough. Wooden design will then swell, then shrink, shifting the leaves. In any case, the depth of the frame should correspond to the thickness of the foam polystyrene.

Mounting plates

If you decide to do without the sheathing, the bottom still need to beat (or to enclose) smooth bar, adjusted her position on the level. The rail will serve as support for the first row, plus will keep the pasted plates from slipping. Next is the insulation PENOPLEX, the technology of which stipulates a specific sequence:

Plate we start gluing from the bottom, the illuminated angle. At the ends of the sheets have grooves for sealing. Before spreading adhesive it is necessary to check whether the lock groove of the previous sheet. The ends of the cut fragments driven as accurately as possible.

Methods of applying adhesive to the sheets of foam polystyrene

Plate on the perimeter of the coat of glue, add a few thick brush strokes in the middle. If the instructions recommend a mixture to withstand up to a light setting, it is necessary to do so.

Polystyrene is pressed to the wall, rotary motion, dispensing the adhesive. Hold 20-30 seconds. Remove excess glue.

A useful tip! Accuracy of installation of each plate is checked the building level. Gaps in the joints and random defects can be directly glued scraps of foam polystyrene, and adjusting their size.

Technology walls with the use of foam polystyrene

Sheets of insulation are laid with ligation (staggered).

We will also need irregularities of the plate. In difficult places (between the openings near the outlets) applied to the wall the whole leaf. Note the pencil line cutting. To cut polystyrene is with a hacksaw with fine teeth.

In the openings of the insulation glue the overlap to the edge of the slope. Closing soffits customized fragments, carefully cut away the excess foam polystyrene. To the door and window boxes fasten the profile of contiguity and sticking polystyrene is close.

Fastening of insulation nails

The adhesion of the glue goes a few days. Making sure that the polystyrene is well kept on the wall, reinforce the attachment of the insulation plate nails (umbrellas). It is better to take the plastic nails and dowels. They are cheaper than metal and does not conduct the cold.

Calculate the length of the fungi. The thickness of the foam polystyrene add 1 cm of glue and 4-5 cm of the wall. For example, for a plate of 50 mm need to take nails with a length of 11 cm.

Ways of fastening of sheets of foam polystyrene

Drilled by drill holes in the corners and in the middle of each sheet. In the corners of the drill so that the nail head seized the edge of the adjacent plate. The depth of the socket shall exceed the length of the umbrella 2 cm

Inserted into prepared holes the plastic dowels, inciting them, then nailing.

If the process of fixing the formed joints, fill them with foam.

Reinforcement foam polystyrene mesh

After warming the walls with foam polystyrene construction involves the reinforcement surface. It is necessary to strengthen the thermal insulation layer and also for better adhesion of the plaster with insulation. The order of works is as follows:

  • cut the glass cloth (metal) mesh in pieces of 1 sq m;
  • apply to the area of the insulation adhesive layer with a thickness of 2-3 mm;
  • superimpose a grid and even out the adhesive, utaplivaja it. If not enough glue is added, until the grid will be hidden under it completely. The edges of the fiberglass a few inches leave not glued;
  • coat the adjacent site, going with a spatula on the edge of the previous. Fasten a new piece of mesh, making of lap joints. After setting, the mortar joints will be invisible.

Once the reinforcing layer has dried, it must be trowelled with an abrasive. Then apply two to three leveling layer of adhesive mixture, and each of them dried within 24 hours. Dry surface can be primed and plastering.

In conclusion. The result of plating the walls of PENOPLEX immediately noticeable. Housing becomes warm and dry, decrease the cost of heating. If, in addition, the foam polystyrene to insulate the floor, roof and Foundation, the house will be truly energy efficient.
