Secrets of polystyrene foam insulation facade technology

Application technology warming house facade polystyrene - an affordable and effective method of thermal insulation, allowing a significant reduction in utilities costs.

Besides polystyrene is exactly the material, which can work independently and without any special skills.

Thermal insulation based on polystyrene is produced in the form of sheets of square or rectangular shape.Outwardly resembles the usual foam.

But unlike it has a more rigid and dense structure, as well as special connecting recesses on the perimeter - the grooves.

Through them, at warming your hands house facade extruded polystyrene foam, it turns the plane without gaps between the sheets, which in turn reduces the rate of heat transfer walls.

addition to thermal insulation of facades, polystyrene sheets are often used for insulating intermediate floors, basement, basement, balconies and loggias.

For each case selected products with different thickness and density, not forgetting that the sheets of polystyrene foam is denser and thicker the insulation material above.

And if the facade walls themselves have a dense structure, it is not recommended to carry out their expanded polystyrene insulation with high density.

wall is difficult to breathe, that threatens the formation of condensation and subsequent destruction.

Benefits of using Styrofoam

Aspractice shows that the facade insulation with polystyrene foam has a lot of positive moments.Lightweight material requires no facade is sheathed by high load carrying properties.

In addition, the transportation of forest products in place without the use of special mechanical force.
technology is also available Styrofoam insulation sheets of the new facade of the house.

material is endowed with good compressive strength and tear, which is very important when building starts to weaken.In this case, do not be afraid that the material is deformed and it will break.

In addition, polystyrene is highly resistant to moisture and temperature changes.

During facade insulation, sheets fixed on glue and dowels-mounted umbrellas.

additional hardware is needed, as opposed to styrofoam properties not resist moisture, adhesive under its influence over time loses its strength.

Among the shortcomings that exist in any of a heater, it is worth to point out the deformation of the material, resulting in a point of the high temperature.As well as the low level of sound absorption and vapor permeability.

How to prepare for wall insulation

Before large-scale facade insulation extruded polystyrene foam, developed estimates.

Prepare the surface of the exterior walls of the house with his own hands sheathe window soffits and doorways.

In order to ease the workflow and obtain the desired quality of thermal insulation surfaces, the alignment base substrate.

Noticeable differences formed by protrusions and recesses on the front, in order to avoid breaches is minimized, to approximately 1.5 cm

Facade equip guiding beacons, with their help, leveling plaster applied..

If the facade is exfoliated sections of the old coating, they are cleaned.After all, it will depend on the strength of finishing setting the two bases.

If the finishing layer of the wall was made using pentaphthalic enamel paint, it must be completely removed.

If the quality of the facade is close to ideal: when a hand on the wall, his hand remains clean, with no traces of plaster, it is possible to carry out insulation at neprogruntovannuyu basis.

When shedding sand from the walls of the facade, it is recommended to carry out their thorough cleansing.Then, the plaster should be primed with a sprayer or brush, with his hands to hold luting surface.

Mounting slopes and outdoor tide

After the relief is over, go directly to the insulation does not work, because you need to spend some time on the slopes installation on doors and windows, as well as the installation of external window sills.

width of the window sill or outdoor tide depends on the thickness of the sheets of polystyrene foam.

Video:

Determine the desired width of the tides can be achieved by adding to the thermal insulation layer width allowance of a few millimeters.

As a result, the edge of the tide has to be above the level of insulation surface at 3-4 cm. This technology does not allow the installation of rain water to fill a wall under a window sill.

If you do ebb even wider, while in the rain in the house will hear the beat drops on the window sill.From

properly installed flashings own hands depends on the properties window does not pass moisture.PVC windows have a special recess, through which it is possible to build in quality low tide.

Regarding the arrangement of slopes, for them polystyrene acquired smaller thickness than for insulation of the facade.The sheet product is selected considering the fact that during assembly it is not found on the glass.

As a rule, for insulation layer slopes is 25-35 mm plus the thickness of the adhesive.According to these data, you can calculate the desired product thickness.

Installation Styrofoam on facade

polystyrene Warming facade is divided into two stages.

The first stage is carried out fixing the sheets with his hands, using the adhesive on the second - to conduct additional mounting plates with dowels.

Do it when the glue is completely dry.double fastening technology provides a guarantee that the polystyrene over time will not slide off the wall of the wind load.

Especially important is fixing material for the facades of tall buildings.

Warming carried out from bottom to top, it is necessary to equip the foundation plinth guide plates (starter profile).On it will draw the first lower range of products.

If the guide does not equip the starting surface, there is the risk of sliding into sheets of expanded polystyrene before the glue dries.

In addition, the second and subsequent rows of plates usually mounted to the hardening of the first row.

For fixing plates use a simple comb and spatula.Spatula comb is used for applying adhesive on foam board, provided a well-lined walls.

usual trowel adhesive is applied to the substrate with large differences, the method of "lyapa".

the expense of what it is possible to visually determine the thickness of the adhesive "lyapa", and with his help to correct uneven.

Once the adhesive is applied to the façade surface or one side of the heater, with their own hands the sheet is applied to insulate the surface so that its long side lay horizontally.

thus performed the entire first row, second row - placed by the offset (ligation joints) masonry technology, we must not allow the retaining structure has appeared between the joints of sheets of expanded polystyrene.

ensuring this fire, all around facade openings, the device fire protection zones of fire-retardant insulation, for which you can use mineral wool.

then each foamed polystyrene and mineral wool products additionally fixed with dowels, umbrellas, to be included in the support base is not less than 5 cm.

Add the mechanical strength of the entire insulating layer allows the use of perforated aluminum bracket.

facade cladding insulated house siding

With the purpose of additional insulation and decoration of the facade of the house, with their hands perform the trim using a wooden or other types of siding.

Before constructing crate under the siding of timber or metal galvanized profile.

Frame crates of metal sheets or wooden beams under the siding necessarily installed around door and window openings.

On the wall sheathing under siding fixed vertically, with the distance between the rails no more than 50 cm

layer on the pre-glued to the wall insulation is better to collect a lath of metal sheets or wooden beams under the siding on the suspension..

Due to the achieved output gap will façade with good ventilation.

If the foundation wall built of wooden material, for mounting batten siding for use nails or screws with a long rod.

Construction guide for crates and brick masonry performed by anchors or screws with plastic plugs.

Installation of wooden siding operate from the bottom up.Previously having equipped base guide elements of a wooden or metal material.

siding panels should be slightly shorter than the distance between the guides, besides siding is not recommended to mount tautly.

Each panel is fixed to a batten so that there is a gap of 1 mm between it and the mounting cap.

If necessary, shorten the siding using a grinder or a hacksaw.

supplement the above material will allow thematic video.
