This article will tell you about the use of insulation materials, without which the heat loss is the third part. This badly affects the microclimate of the house, and also increases the cost of heating. To avoid this, you need to understand the types of materials on the market, and buy insulation for the roof. You will learn what tasks the heater should solve: reduce heat loss, create noise insulation and extend the life of the roof structures.
Material that is used for insulation, must meet the following requirements:
Long life. It is important to choose a product that will last more than 30 years, then you will not have to return to construction work for a long period of time.
Ability to preserve shape and not to deform. This characteristic indicates a high quality insulation for the roof, the price of which will be slightly higher.
A small weight will simplify transportation and its installation on the roof. In addition, the load on the structure will be reduced and the total cost of the work will be reduced.
Fire resistance. The material must be made of non-combustible raw materials, which will increase the fire safety of the entire structure.
Moisture resistance. Moisture adversely affects the insulation, reducing its properties. High quality material indicates its ability to withstand water.
Noise Isolation. This is rather an additional characteristic, but if the roofing material is chosen that creates noise, then this will be an important advantage.
Ecological safety. You need to choose a heat insulation that does not smell, does not emit harmful substances and is environmentally friendly.
When choosing a material, you need to know that insulation on the roof of the house at a price has a wide variation. Depends on the thickness of the type and density of the manufacturer of the goods.
First of all, you need to determine whether the attic is full living space or not. If the answer is yes, then you will have to insulate the walls, slopes of the roof and floors. In the second version, only overlaps will suffice.
It is necessary to select the thickness of products in accordance with the climate where it is planned to use it. For example, a material with a thickness of 150 mm is recommended to be used at temperatures not lower than -15 degrees. If you apply it at lower temperatures, then condensation may occur, which adversely affects the finishing of the room. The stores found insulation for the roof of 150 mm at a price of 900 to 1500 rubles.
There are several options for thermal insulation and its manufacturing techniques. It is necessary to choose, based on the type of roof, roofing material, construction features and climatic conditions of the region where it is planned to use insulation. Below are the main types that are on sale. To select a product, you should familiarize yourself with its features, advantages and disadvantages.

For reliable protection of the roof against the cold, these types of insulation are used:
Basalt wool slabs (price from 250 rubles to 1300 rubles depending on the manufacturer). It is a natural material that is used for flat roofs and is laid on a concrete or metal base. The choice of products is carried out in accordance with the coefficient of density and thermal conductivity.
Glass wool is used on flat or a sloping roof (price from 500 rubles to 1440 rubles). It has high environmental friendliness and fire resistance. Suitable for use in wooden buildings, as well as built of brick and foam concrete. A comfortable microclimate is created in the premises, however, it is necessary to provide insulation in order to avoid glass falling on the skin and into the air.
Extruded polystyrene foam is a cellular structure. It has a high thermal efficiency. Due to its high moisture resistance, environmental performance and lack of shrinkage, the material is popular among buyers. In addition, it is easy to lay, no special skills and knowledge are required. The cost of the material is from 900 rubles. up to 1600 rubles
The lightest of all The presented heaters are foam plastic. It is good to apply on the roofs of old buildings. Price from 815 rubles. up to 5,000 rubles

Staple fiberglass is a material with good vapor permeability. It has a low cost. If you need insulation for the roof, the price of which is lower than the mineral wool, then choose mats or fiberglass plates. Scope of application - insulation mansard rooms. Price ranges from 700 rubles. up to 1700 rub.
Penofol - it is polyethylene with a foil basis. With it, make the insulation of pitched roofs. Depending on the thickness of the material and the volume of the roll, the cost varies from 700 rubles. up to 4,000 rubles.
If you prefer natural materials, you should buy insulation for the roof of basalt fiber fibers.
It has a number of undeniable advantages:
coefficient thermal conductivity;
environmental friendliness and safety for humans;
withstands high temperatures;
material inert to chemicals;
the relative cheapness of the product;
high sound absorption.
The listed advantages make basalt cotton wool in demand for insulation of roofs, floors, suspended ceilings and wooden floors. On sale it is found in rolls, mats or plates. It is important to know that for the laying of this material will require the manufacture of crates. This mineral wool for roof insulation, the price of which ranges from 220 to 1,300 rubles, is one of the cheapest options for roof insulation.

A material is made from glass fibers that melt. It also refers to safe natural products.
distributor. You can find glass wool in rolls, mats or slabs for sale. Its advantages are the following qualities:
good thermal insulation;
high strength and elasticity;
low weight, which allows not to create an additional load on the structure;
not affected by moisture, corrosion, mold;
withstands high temperatures;
If you choose foil-coated plates, you will not need a vapor barrier. When installing glass wool (price range for work is 50 - 70 rubles / m2) without a foil layer, the following sequence of work must be adhered to:
A frame (lathing) is created.
A membrane film is applied, fixed with a stapler on the surface.
Insulation boards are laid.
It is important to avoid contact of the material with the skin, because it causes irritation, therefore, work is carried out in overalls with the use of protective eyewear and a respirator.

It is a lightweight synthetic product with a porous structure that has low moisture absorption and thermal conductivity. In addition, it is not amenable to mechanical stress and is chemically inert.
It is easy to stack polystyrene foam, you do not need to have special skills construction. Long service life makes it popular among consumers. Low weight allows you to use this material in old buildings, because it does not create an additional load on the structure. It is used as insulation for a flat roof. Also able to create additional sound insulation.
The advantages of extruded polystyrene are:
resistance to freezing and thawing (up to 1000 cycles);
can be used in temperature range from -50 to +75 degrees;
the ability to withstand heavy loads.
Material disadvantages are vapor tightness and combustibility. You should not use it for warming flat roofs. The cost of work is about 70 rubles. per square meter. It is laid in the following sequence:
A waterproofing layer is created.
The layer of plates is mounted, it is necessary to ensure a tight fit.
The joints are filled with mounting foam and sealed with reinforced tape.

When choosing insulation for the roof, the main factors are the climate of the region where it is planned to use the products, the material for the manufacture of the roof and its type (flat or pitched), the construction features of the building, the price of the goods do without technical tools and special skills. Considering all these moments, you can choose the appropriate insulation, which will last a long period of time and allow you to save on heating.
