If you are thinking about which insulation is best for the roof, then it is worth considering several options at once, from which you can make a choice.
Varieties of insulation
In the building materials market today one can find various heat-insulating materials, including foamed polystyrene foam, polyurethane foam, glass wool, mineral wool and slag.
Expanded polystyrene is a lightweight material that is most often used for warming flat roofs. If you choose a heater for the roof of the bath, which is better to determine at the initial stage. Expanded polystyrene can be an excellent solution, but it is also suitable for attics. It is characterized by durability and low weight.
Polyurethane foam is a gas-filled plastic that is able to retain heat without letting in steam and moisture. This material is also characterized by low weight, durability.
Glass wool, in the production process of which molten glass or waste from its production is used, resembles mineral wool in characteristics. However, it has a lower thermal threshold, which varies between -450 degrees. This material has excellent sound absorbing and heat insulating qualities. It is not able to absorb moisture, has frost resistance and does not crumple even during prolonged use.
That's what a roof insulation is. Which is better? Price may allow you to understand. Mineral wool can have a different structure. It can be layered, corrugated, spatial or vertically layered material. This allows you to use this insulation for various surfaces. Mineral wool holds sounds well and retains heat, moisture can affect it, which does not contribute to the loss of quality characteristics. This insulation 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 are faced with the question of what insulation is better for the roof, then it is important to determine the main factors that you should pay attention to when purchasing.
Thus, the material should be characterized by low weight, only this way it will be possible to eliminate unnecessary loads on the building. That is why experts recommend paying attention to density. For many modern consumers, environmental friendliness is a priority, therefore it is worth choosing a heater that is free from odors and also does not emit toxic substances into the outer space. Pay attention to the life span, which should exceed 50 years. In this case, the material should have the ability to maintain its quality characteristics. For private houses, fire safety is especially important, a heater for the roof should have this property.
What is important to know before shopping
If you are thinking about which insulation is better for the roof, then experts recommend paying special attention also to the stability of the material shape. This indicator indicates the ability of a good fit of the insulation to all elements of the roof, which is considered very important. It is important when conducting such work to eliminate the occurrence of gaps. Therefore, the masters of their craft do not choose high-density heat-insulating materials that will be used for pitched roofs. Despite the widespread prevalence of expanded polystyrene and other forms of polystyrene, this material is not used so often for work in the field of pitched roofs. This is due to the fact that the canvas is not able to provide a sufficiently tight fit to the rafter system. Even if you use expanded polystyrene in tandem with polyurethane foam, the work will not bring the expected results. If it is not possible to achieve a tight fit, then this may cause the occurrence of cold bridges, as well as the subsequent formation of condensate. When choosing mineral wool, it is also necessary to exclude materials that have a fairly impressive density.
Thermal insulation selection
If you have a question about which insulation is better for the roof, then, drawing a conclusion from the above, it can be noted that glass wool or a basalt plate are the most acceptable materials. In case of accidental fire, the material should not ignite, emit smoke, among other things, it should prevent the spread of fire. These characteristics just have the two aforementioned insulation. When visiting the store, be sure to pay attention to the maximum combustion temperature, which is indicated by the manufacturer. If there is a need for high-quality sound insulation, then 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 an attic roof, which 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 manipulations does not exert impressive pressure on the walls and foundation of the house, then glass wool should be preferred. It, if compared with mineral wool, has a smaller mass. If you have to work in the space of the attic roof, then the canvas is most often installed between the elements of the rafter system. When using mineral wool, the material will creep under its own weight. While fiberglass, which has an acrylic-latex binder, will be quite tightly fixed in full space.
Rockwool Basalt Thermal Insulation
Choosing a heater for the attic roof, which insulation is better - it is worth asking professionals. For example, Rockwool meets all the requirements of an attic type roof device. Due to the fact that the fibers are partially arranged vertically, the described mineral wool brand has a stable shape, which positively affects the insulating characteristics. Rockwool is a rigid plate that has a different classification. Thus, the material can be universal, as well as intended for the lower and upper layer of the roofing cake.
Use of foam glass
If you choose a heater for the roof of the attic, which material is better, it is worth deciding a long time before the start of work. Today foamglass is very common, which has an ethical structure. The material does not dissolve under the influence of water, is fireproof and is not exposed to alkalis and acids. The layer does not allow moisture and steam to pass through, therefore foamglass is most often used in cases where the use of other insulation materials is unacceptable. If you choose between polystyrene foam, polyurethane foam, some types of mineral wool, where formaldehyde resin is used, as well as foam glass, then you should prefer the latter option, which is completely safe for human health and the environment. Despite the fact that the insulation begins to melt when exposed to a flame, it does not emit toxic substances into the outer space, as well as caustic poisonous smoke.
Biological inertness
In the space of an unheated attic, temperature and humidity changes are quite often noted, so some heaters are not able to deal with mold, fungi and putrefactive formations. What can not be said about foam glass - such phenomena cannot occur on its surface. If you are thinking about which insulation for the roof is better, read the reviews - they are presented in this article.
Foam glass consumer reviews
Buyers who used foam glass to equip the roof, note that the material has quite impressive strength. This is confirmed by comparison with other materials. That is why it can be used for thermal insulation of soft roofs. Inexperienced masters, who are first involved in arranging a thermal insulation system of the roof, try to choose foam glass, this is due to the fact that working with it is quite simple because of its light weight. Thus, a cubic meter has a mass equal to 180 kilograms. If there is a need for noise protection, then, as owners of private houses note, it is worth using the mentioned material. The degree of sound absorption of these paintings is equal to 52 decibels. This is true if the layer thickness is 100 millimeters. Working with sheets of this insulation material is quite simple, it is easy to process and quickly mounted. It can be cut and drilled, which is why, as builders emphasize, it can be nailed and, if necessary, strengthened with self-tapping screws. If you are thinking about what kind of insulation it is better to insulate the roof, then the foam glass after installation can also look very aesthetically pleasing if it is plastered with special compounds. This material can also be glued to the surface, and compositions recommended by the manufacturer should be used. After completion of the insulation work, this material can be used for 50 years or more.
Conclusion
If you have a question about what insulation is better for the roof of a wooden house, then you can use ecowool. Its price is 600 rubles per package.
