Expanded polystyrene for underfloor heating

Walling should be qualitatively warmed to the climate became as comfortable as possible indoors.

To avoid unnecessary heat loss, the formation of mold, fungi and condensate, wide application received polystyrene for underfloor heating.

Professional builders attribute it to one of the most optimal, reliable and modern materials.

market Choosing polystyrene

In most cases, expanded polystyrene for water floor heating is a plate of various colors (usually blue)which at first glance look like foam.

This material is one of the types of foam that is obtained by connecting two atoms elements, hydrogen and carbon.

It is the result of expansion of the extruded granular material with a volatile type of oil.To obtain the desired effect applied dry water vapor.

The most popular among potential buyers won extruded polystyrene for underfloor heating.

He is one of the best insulators, having low thermal conductivity.

Another characteristic that can be attributed to the significant advantages the material - low capillarity and low rate of water absorption and its vapors.

thermal conductivity of expanded polystyrene does not change even under the constant exposure to moisture.

have extruded polystyrene foam is one of the lowest among thermal insulation materials index vapor permeability.

have a layer thickness of 2 cm, it is comparable to the same period of roofing material.

Recently, the market is rich in products that have a low coefficient of combustibility due to the addition of the special fire retardants.

It does not change its physical properties over a wide operational temperature range - from -50 to + 85 degrees.

Among other important advantages distinguish:

• Eco-friendly material;
• is unfavorable breeding ground for fungi, molds and pathogenic bacteria;
• is resistant to chemical compounds;
• material density - 33-38 kg / m.cube;
• Easy to use and installation.

increasing spread began to receive foil styrofoam for warm floor.

Its distinguishing feature - a metallic finish, which is located on both sides of the thermal insulation material.

One advantage of the variety of expanded polystyrene - durability.According to the manufacturer it is able to serve more than 70 years at an operating range from -40 to +40 degrees.

Foil protective layer makes thermal insulator resistant to solvents and other corrosive environments.

However, without the addition of flame retardants belong to him easily combustible materials (flash point - a modest 210-220 degrees).

therefore recommended to buy the material on which the brand is the end of the letter "C".

Getting laying

Before laying underfloor heating on a concrete slab or cement-sand screed, you must create a work plan and follow it strictly.

Stack polystyrene under floor heating can be their own hands, because the technology works is very simple.

First floor joists need to put wooden boards.It is generally recommended to use a timber the size of 10x10 cm, but with insufficient height of the room can be used timber 5x5 cm.

wood must be flat and dry, impregnated with antiseptic substances.

next stage - laying the substrate between the joists.We recommend using a polyethylene tape, which is used as a lining under the laminate.

recommended extruded polystyrene foil laid under the floor heating, which will serve as a kind of screen that reflects heat back into the room.

They blanketed the entire area between the lag.Then, on top of the insulation will be installed tube made of metal, which will flow the coolant.

recommended to make a little distance between joists -. 50 to 80 cm

order not to make a mistake and do not cut in the future insulator without harming its structure, first buy the material and customize its size under the boards.

All logs must be placed in the same plane to the surface finishing sexual exactly lying.With

substrate edges are wrapped to side lag and nail by means of staples or small galvanized nails.

If the concrete subfloor is not in perfect condition (the set of depressions, mounds, cracks and chips), it is necessary to improve it.

now spread extensively profiled polystyrene for underfloor heating.

Its main feature - the presence on the surface of the projections, which are passed to the coolant pipe.He excludes their longitudinal and transverse vibrations.

Prices

market these days to buy a styrofoam for floor heating system can be in the shops and markets.

recommended trusted manufacturers that have proved themselves among consumers for many years.

Today, the price of polystyrene for underfloor heating can vary within a very wide range.

cost of one square meter starts from a modest 25 in.e., however well-known manufacturers materials can reach a price of up to 150-200 at.e.
