The roof of a private house can surely be called a launching pad in a bright future. The most promising roof insulators find their approval here. The first timid attempts of mankind to warm the roofs of the dwelling with moss lichen convincingly talked about the hidden possibilities of heaters on a world scale. That's why today we have reliable and warm roofs.

If you need to insulate the roof of a private house
The abundance of materials for insulating the roof of a private house, as well as the process of warming itself, certainly depends on the type of roof. How is it recommended to insulate roofs: inside or outside?
If the private house has a pitched, attic or type of residential attic roof, it is recommended to insulate from inside it is the ramp. The warming of the inclined planes between the rafters was known a long time ago. For warming, hemp and straw were used.
Primitive roof insulators in this design allowed winter to winter, and with the onset of cold weather, "warming" with hemp or straw was repeated again. The warming of the roof in the wooden house was, is and will be associated with considerable labor costs, and it must be said frankly did not always justify the hopes for a warm existence.
However, the rapid development of insulation technology is currently a successful symbiosis of high-quality materials and engineering approaches to solving the problem of warming. Today, professional insulation of the roof of the house with their own hands is simple.
What materials can be used to insulate the roof
The most popular insulants for under-roof space are materials from inorganic and organic raw materials:
• Polyfoam, polyurethane foam and expanded polystyrene sheets
• mineral wool plates
• liquid polyurethane foam
• Foam concrete
• hemp.
The list of roof insulation materials is based on the recommendations of professional builders. Therefore, it makes sense to get acquainted in the best way with the technical and operational characteristics of heaters.
Styrofoam or expanded polystyrene with a coefficient of thermal conductivity λ = 0,033-0,037 W / (mK) and density from 11 to 35 kg / m3 is a combustible toxic material that gradually degrades under the influence of UV rays. Insulation of foam roof from the inside can be called an old-fashioned and unjustified method of warming.
A mineral wool warmer, the owner of the thermal conductivity coefficient λ = 0,041-0,044 W / (mK) is the most popular insulation that is used as a thermal insulation not only of the roof, but also of the walls of the private house. Successfully matched type of mineral wool from slabs or rolls will make it possible to warm the roof of the frame house in a few hours. As a result - amazing sound and heat insulation.
The surface, insulated with a liquid PPU (foamed polyurethane), will be closed with a monolithic strong layer. A good coefficient of thermal conductivity PPU λ = 0,022-0,028 W / (mK) and the speed of application of a heater allow the work to be carried out in the shortest possible time. The heat-insulating layer that appears literally before our eyes is a guarantee of comfortable living.
What is the process of roof insulation
roof insulation from the inside
The process of roof insulation always requires the right choice of insulation material and phased installation of thermal insulation materials. It is naive to assume that the same heater is suitable for all types of roofs. So, for example, making insulation of pitched roof, it is necessary to solve not only operational tasks, without taking into account the strength parameters of the roof itself.
Therefore, there are certain rules, with respect to which you can be guaranteed to insulate the roof of a private house. Recall some of these rules. The layout and flooring of heat and waterproofing material for the roof must be made taking into account the presence of existing ventilation holes. Plates of heaters are staggered, with a tight fit of each plate or sheet. The process of roof insulation can be carried out from the inside, by making the insulation of the attic or ceiling.
Thermal insulation of the roof of the house from the inside is traditionally carried out as follows. Between the rafters, a crate is installed, on which the heat-insulating material is subsequently fixed.
It is desirable that the density of the material for thermal insulation is not less than 50 kg / m3. The thermal insulation material from the roof side is protected with a waterproofing film, and on the side of the room, the membrane is vapor-insulating.
roof insulation outside
An entirely different principle of roof insulation of a private house will be in case the roof has a flat construction. Well, here to make the roof insulation using foam, straw and hemp will look naive and comical. Which heaters are recommended for use in this case?
Choosing a thermal insulation for the flat roof of a private house, it is necessary to take into account sufficiently high requirements regarding the stability of the surface to mechanical loads. Therefore, the most suitable insulation are the plates of extruded polystyrene foam. For the device of a heat-insulating layer of a traditional flat roof plates from mineral basalt wool, possessing incombustibility are used.
As a heater of the inversion roof, plates made of extruded polystyrene foam are used. This insulation features good thermal insulation characteristics in a humid environment. The coefficient of thermal conductivity of the insulation in the dry state is λ = 0.037 W / mK. In addition, the water-repellent properties of the insulation are no more than 0.2 percent.
For the insulation of the roof outside the slab, the hydrophobic heat insulation from expanded polystyrene extruded is a practical option. Fastening of a heater is carried out with application of special fasteners: poppet dowels with thorns with the increased form of the holder.
Thus, the right choice of insulation for the roof of a private house and the subsequent installation of it depend strongly on the owner of the house. We add that the Internet is full of photos and descriptions of the necessary materials. It remains for small - to insulate the roof of a private house with their own hands.
