If you are thinking about which insulation is best for the roof, then you should consider several options at once from which you can choose.
Varieties of insulation
A variety of thermal insulation materials can be found on the building materials market today, including expanded polystyrene foam, polyurethane foam, glass wool, mineral wool and slag wool.
Expanded polystyrene is a lightweight material most commonly used for flat roof insulation. If you choose a heater for the roof of the bath, which one is better, it is important to determine at the initial stage. Expanded polystyrene can be a great solution, but it is also suitable for attics. It is durable and lightweight.
Polyurethane foam is a gas-filled plastic that is able to retain heat without letting in steam and moisture. This material is also lightweight and durable.
Glass wool, in the production process of which glass melt or glass waste is used, resembles mineral wool in terms of 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 wrinkle even after prolonged use.
This is what roof insulation is like. Which is better? The price might make it clear. 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 retains sounds well and retains heat, it can be affected by moisture, which does not contribute to the loss of quality characteristics. This insulation is not afraid of rodents and withstands high temperatures, and is also not afraid of interaction with chemicals.
Recommendations for choosing insulation
If you are faced with the question of which insulation is best for the roof, then it is important to determine the main factors that you should pay attention to when purchasing.
Thus, the material should have a slight weight, only in this way it will be possible to eliminate unnecessary loads on the building. That is why experts recommend paying attention todensity. For many modern consumers, environmental friendliness is a priority, so you should choose a heater that is devoid of foreign odors, and also does not emit toxic substances into the external space. Pay attention to the life span, which should exceed 50 years. In this case, the material must be able to maintain its qualitative characteristics. For private houses, fire safety is especially important; roof insulation should have this property.
What you need to know before shopping
If you are thinking about which insulation is best for the roof, then experts recommend paying special attention to the stability of the shape of the material. 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 carrying out such work to exclude the occurrence of gaps. Therefore, masters of their craft do not choose high-density thermal insulation materials to be used for pitched roofs. Despite the ubiquity of expanded polystyrene and other forms of foam, this material is not used so often for pitched roof work. This is due to the fact that the canvases are not able to provide a sufficiently tight fit to the rafter system. Even if you use expanded polystyrene in tandem with polyurethane foam, then the work will not bring the expected results. If it is not possible to achieve a snug fit, then this can cause the formation of cold bridges, andas well as the subsequent formation of condensate. When choosing mineral wool, it is also necessary to exclude materials that have a fairly impressive density.
Choice of thermal insulation
If you are faced with the question of which insulation is best for the roof, then, drawing a conclusion from the foregoing, it can be noted that glass wool or bas alt slab are the most acceptable materials. In the event of an accidental fire, the material must not ignite, emit smoke, among other things, it must prevent the spread of fire. These characteristics are just possessed by the two above-mentioned heaters. When visiting a store, be sure to pay attention to the maximum combustion temperature 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 mineral wool insulation, which is known as Ursa.
Weight is one of the main criteria
If you choose insulation for a mansard roof, which insulation is better - you need to decide even before visiting the building materials department. If it is important for you that the roof structure after the manipulation 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 canvases are most ofteninstalled between the elements of the truss system. When using mineral wool, the material will slide under its own weight. Whereas fiberglass, which has an acrylic-latex binder, will be quite tightly fixed in a full space.
Rockwool bas alt thermal insulation
When choosing insulation for a mansard roof, which insulation is better - you should ask the professionals. For example, Rockwool meets all the requirements for a mansard roof. Due to the fact that the fibers are partially arranged vertically, the described brand of mineral wool has shape stability, which positively affects the heat-insulating characteristics. Rockwool is a rigid slab that has a different classification. Thus, the material can be universal, and also intended for the lower and upper layers of the roofing cake.
Using foam glass
If you choose insulation for the roof of the attic, what is the best material, it is worth deciding a long time from the start of work. Foam glass, which has an ethical structure, is very common today. The material does not dissolve under the influence of water, is fireproof and is not affected by alkalis and acids. The layer does not allow moisture and steam to pass through, so foam 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, as well as foam glass, then you should prefer the latter option, which is completely safe for human he alth 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 external space, as well as caustic poisonous smoke.
Biological inertia
In the space of an unheated attic, changes in temperature and humidity are often noted, so some heaters are not able to fight mold, fungi and putrefactive formations. What cannot be said about foam glass - such phenomena cannot occur on its surface. If you are thinking about which roof insulation is better, the reviews are worth reading - they are presented in this article.
Foam glass consumer reviews
Buyers who used foam glass for roofing, 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 craftsmen, who are first engaged in arranging a roofing thermal insulation system, try to choose exactly foam glass, this is due to the fact that working with it is quite simple due to its low weight. Thus, a 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. Degree of data noise reductioncanvas is 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 the builders emphasize, it can be nailed, and, if necessary, strengthened with self-tapping screws. If you are thinking about what kind of insulation 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, using the compositions recommended by the manufacturer. After completion of insulation work, this material can be used for 50 years or more.
Conclusion
If you are faced with the question of which insulation is best for the roof of a wooden house, then you can use ecowool. Its price is 600 rubles per pack.
