Which insulation is better for the roof: a review, varieties and testimonials. Insulation for the roof skylight

If you are thinking about what kind of insulation is better for the roof, then you should consider several options at once, from which you can make a choice.

Types of insulation

On the market of building materials today you can find various heat-insulating materials, among them - foamed polystyrene foam, polyurethane foam, glass wool, mineral wool and slag wool.

Styrofoam is a lightweight material that is most often used to insulate flat roofs. If you choose a heater for a roof bath, which is better to determine at the initial stage. Styrofoam can be an excellent solution, but for attics it is also suitable. It is distinguished by its durability and low weight.

Polyurethane foam is a gas-filled plastic that is capable of retaining heat without passing steam and moisture. This material also differs in insignificant weight, durability.

Glass wool, in the process of production of which glass melt or waste of its production is used, resembles mineral wool according to characteristics. However, it has a lower thermal threshold, which varies between -450 degrees. This material has excellent noise-absorbing and heat-insulating qualities. It is not capable of absorbing moisture, has frost resistance and does not crumble, even during prolonged use.

That's how the insulation for the roof. Which is better? The price, perhaps, will allow to understand. Mineral wool may have a different structure. It can be a laminated, corrugated, spatial or vertically-laminated material. This allows you to use this insulation for various surfaces. Mineral cotton wool keeps sounds well and keeps heat, it can be affected by moisture, which does not contribute to the loss of quality characteristics. This heater is not afraid of rodents and can withstand high temperatures, and also does not fear interaction with chemicals.

Recommendations for choosing a heater

If you have a question, what kind of insulation is better for the roof, then it is important to determine the main factors that should be paid attention to during the acquisition.

Thus, the material should be characterized by a light weight, only this way it will be possible to exclude unnecessary load on the construction. That's why experts recommend paying attention to the density. For many modern consumers priority is environmental friendliness, so it is worth choosing a heater that is free from extraneous odors, and also does not emit toxic substances into the external space. Pay attention to the period of life, which should exceed 50 years. In this case, the material must be able to maintain its quality characteristics. For private houses, fire safety is especially important, such a property should have a heater for the roof.

What is important to know before shopping

If you are thinking about what kind of insulation is better for the roof, then experts recommend paying special attention also to the stability of the shape of the material. This figure indicates the ability of a good fitting of the insulation to all elements of the roof, which is considered very important. It is important to exclude the appearance of gaps when carrying out such work. Therefore, the masters of their business do not choose high-density thermal insulation materials, which will be used for pitched roofing. Despite the general prevalence of expanded polystyrene and other forms of foam, this material for work in the field of pitched roofs is not used so often. This is due to the fact that the canvas is not able to provide a sufficiently tight fit to the rafter system. Even if we use expanded polystyrene in tandem with a mounting foam, the works will not bring the expected results. If it is not possible to achieve a close fit, this can cause cold bridges, as well as the subsequent formation of condensation. When choosing a mineral wool, it is also necessary to exclude materials that have a rather impressive density.

Choosing thermal insulation

If you have a question about what kind of insulation is better for the roof, then, drawing a conclusion from the above, it can be noted that the most suitable materials are glass wool or basalt slab. In case of accidental fire, the material should not be ignited, smoke should be released, among other things, it must prevent the spread of fire. These characteristics are just the two above-mentioned insulation. When visiting the store, always pay attention to the maximum combustion temperature, which is specified by the manufacturer. If there is a need for high-quality noise insulation, the sound absorption index should be taken into account. The highest index has a mineral wool insulation, which is known as Ursa.

Weight is one of the main criteria

If you choose a heater for a roof skylight, what kind of insulation is better - you need to decide before you visit the building materials department. If it is important for you that the roof structure after carrying out manipulations does not exert an impressive pressure on the walls and foundation of the house, then glass wool should be preferred. It, if carried out a comparison with mineral wool, has a smaller mass. If you want to work in the roof space, then the canvas is most often installed between the elements of the rafter system. When using mineral wool, the material will slip under its own weight. Whereas fiberglass, which has an acrylic-latex binder, will be sufficiently tightly fixed in full space.

Basalt heat insulation Rockwool

Choosing a heater for the roof skirting, which insulation is better - it is worth asking the professionals. For example, Rockwool meets all the requirements of a mansard roofing device. Due to the fact that the fibers are partially located vertically, the described brand of mineral wool has a stable shape, which has a positive effect on the thermal insulation characteristics. Rockwool is a rigid board that has a different classification. Thus, the material can be universal, and also intended for the lower and upper layer of the roofing pie.

Use of foam glass

If you choose a heater for the roof of the attic, what is the best material, it is necessary to decide for a long time the beginning of the work. Today foam glass is very common, which has an ethical structure. The material does not dissolve under the influence of water, is fire-safe and is not exposed to alkalis and acids. The layer does not pass moisture and vapor, so foamed glass is most often used in cases where the use of other insulating materials is unacceptable. If you choose between foam, polyurethane foam, some types of mineral wool, where formaldehyde resin is used, and also foam glass, then you should prefer the latter option, which is absolutely safe for human health and the environment. Despite the fact that the heater, when exposed to flames, begins to melt, it does not emit toxic substances into the external space, as well as caustic toxic smoke.

Biological inertia

In the space of an unheated attic, temperature and humidity drops are often noted, so some heaters are not able to fight mold, fungi and putrefactive formations. What can not be said about foam glass - on its surface can not arise similar phenomena. If you are thinking about what kind of insulation for the roof is better, reviews worth reading - they are presented in this article.

Comments of consumers about foam glass

Buyers who used foamed glass to arrange the roof, note that the material has an impressive strength. This is confirmed when compared with other materials. That is why it can be used for the thermal insulation of soft roofs. Inexperienced masters, who are engaged in the construction of the thermal insulation system of the roof for the first time, are trying to choose foam glass, this is due to the fact that it is quite easy to work with it because of its low weight. Thus, the cubic meter has a mass equal to 180 kilograms. If there is a need for noise protection, then, as the owners of private houses note, it is worth using the mentioned material. The degree of noise absorption of these canvases is 52 decibels. This is true if the thickness of the layer is 100 millimeters. Work with sheets of this insulation material is quite simple, it can be easily processed and quickly mounted. It can be cut and drilled, which is why, as the builders emphasize, it can be nailed, and if necessary reinforced with screws. If you are thinking about what kind of insulation is better to insulate the roof, then foamed glass after installation can also look very aesthetic if it is plastered with special compounds. To the surface, this material can also be glued, use should be made of the compositions recommended by the manufacturer. After the completion of insulation work, this material can be used for 50 years or more.

Conclusion

If you have a question about what kind of insulation is better for the roof of a wooden house, then you can use ecowool. Its price is 600 rubles per package.
