process of warming the roof of a private house can reduce heat loss up to 20%.That is to bring tangible economic benefits.You do not need to install additional heaters or think about how to heat a house as a whole.

Rules roof insulation
Online Manufacturers of thermal insulation materials usually indicate all the necessary parameters of the material.
In addition to this, it is important to consider whether residential attic as it windows and its total volume.
In complicated roof structure is important to pertain insulation material, because some insulation in sheet form are not suitable for this work, because of the complexity of the layout together.
Important! additional insulation inside the attic will not be superfluous in terms of soundproofing.Because of heavy rain, in the case of a wooden house roofing metal sheets, making it impossible to stay in it.
In most cases, insulation is carried out in the case of the owners of the attic for residential attic.In this embodiment, it is almost half needs no insulation and soundproofing only.
If you decide to insulate the mansard roof, before starting work, inspect the roof system.It is necessary to check for damp or rot formations, and if available, to try to get rid of those little trouble using antiseptics and special surface treatments.
Important! is mandatory, treat all available wood parts flame retardant.
«Pie" pitched roof, in general, it consists of:
- the insulation layer;
- vapor barrier layer;
- interior decoration.
between the waterproofing layer and directly by the heater, must have a small air spaces appeared to evaporate moisture.
If the owners involve interior trim, for example, clapboard, in this case, between her and steam insulating layer also should leave the minimum clearance.
for good air circulation in the layers, roofers recommend to make the ventilation in the eaves of the roof and in the upper part of the apex.
materials for thermal insulation of the roof
as insulation material is chosen relatively cheap mineral wool.Thermal insulation of mineral wool, easily performed with his own hands and does not require special skills or tools.Suitable for all types of roofs, options complexity of truss construction, and so on. D.
Important! have mineral wool has one drawback - its cheaper brands eventually settle and form a cavity, which can enter the air, thus breaking the uniformity of the general circulation, and as a consequence - dramatically increases the thermal conductivity.
in the roof of a simple design, experts advise to use mineral wool in the form of plates.
One of the most environmentally friendly materials for insulation are, of course, sawdust. roof insulation sawdust bit more complicated than mineral wool, but it's easier than extrusion deposition.
By sawdust materials imposed certain requirements on moisture treatment with antiseptics and fire trains.This will secure the appearance of a layer of insulation various rodents and rot.
Important! sawdust for insulation, thoroughly mixed with calcareous structures.The lime which should be in the range 10-12%.Is stirred to a homogeneous state, and poured into the space between the wooden beams.
Sometimes, if sufficiently large area of the roof, with large volumes of voids filled, there is a problem with a strong flowability.This property provides a specific solution shrinkage, causing unwanted voids in the insulation layer, and the roof is losing heat-insulating properties.
To avoid this, a part of gypsum is added at the rate of 5% of the total weight.
Important!When insulation foam boards have him exactly crate between the rafters, with a special glue.In the process, sometimes using dowels.High-quality foam makes it possible to insulate the roof without any gaps the width of a step rafters to 2m.
Warming of the roof
In a wooden house roof for insulation materials used as mineral or glass wool.This type of insulation is realized in the market of building materials in rolls or sheets.
Also, in a private house builders often recommend the use of foam extrusion or spraying. It is worth noting that if you decide to do with their hands, insulated roof, it is still better to choose the sheet materials, and a method that will allow you to do it without having to purchase special equipment.
In all kinds of ways, and there is thermal insulation waterproofing material which can serve as a layer of high-quality roofing material, impermeable to moisture formed insulation.
vapor barrier materials are plastic film, glassine, but are increasingly used foil materials that unfold the foil into the room.
In some implementations, the roof frame house roofers use a so-called vapor barrier membrane, or as it is called - a vapor barrier.Today, this is perhaps the easiest to install material which does not pass the resulting vapor in a moan, and copes with the condensation drain pointing outwards.
$ insulation for the roof of the house.Price
Today, the market for thermal insulation materials have developed such prices:
- foam - 12-15 hryvnia per square meter, or 35-45 rubles;
- basalt wool - 126-160 hryvnia per package or 400-500 rubles;
- mineral wool - 180-400 hryvnia per roll or 560-1200 rubles;
- extruded polystyrene - 400-500 hryvnia per package or 1,200-1,500 rubles;
- slab heaters from different manufacturers - 12-50 hryvnia per square meter, or 35-150 rubles.
Materials for the roof
The list of materials for the construction of the roof usually include those that are directly included in the "pie" of the roof.In general, the range of applications is quite wide and depends on the choice of the type of insulation and the roof configuration.
The basic list includes:
- tiles (ceramic, flexible metal, composite, sand and cement);
- metal profile;
- steam and waterproofing coatings;
- gutters of different configurations and related items.
Paint the roof
To paint the roof, mostly using special paints for industrial use.The instructions of such paints must be mentioned corrosion resistance as well as resistance to atmospheric influences.Dyes of this class have a high adhesive and fireproof properties.You should not neglect them, because the better part, the longer your roof will look like new.
few years ago, the paint started adding different chemical elements that have contributed to the displacement from the market of certain types of primers, primer prior application was mandatory for painting the roof.
Now on the market of paints and varnishes, you will find many brands of paints, which do not require any prior preparation for painting the roof.
