How much do you know about cement foam insulation boards? Cement foam insulation boards are often used in building external wall insulation projects. Cement foam insulation board is non-combustible material, non-toxic, environmental protection, low-carbon is a new type of material that the country strongly advocates, its fire performance reaches A1 level. The product has high compressive strength (compared with plastic foam), low thermal conductivity, firm bonding with concrete, consistent expansion coefficient, and the same service life as buildings. Is cement foam insulation board good? What are its characteristics? The following will come with me to understand the relevant knowledge of cement foam insulation board .
Cement foam insulation board performance
1, green
No harmful gas and waste emissions, no pollution to the environment.
2, fire resistant
Fire resistance temperature above 1000 degrees Celsius, A1 level.
3, high thermal insulation
The closed cell rate is more than 97%, and the minimum thermal conductivity is 0.045W/m*k, which meets the needs of building insulation.
4, low water absorption
The water absorption rate is low, mildew does not occur, and the safety and durability of the product are ensured.
5, light and strong
Solved the technical problems and achieved relative unity. The density is 180KG per cubic meter, and the compressive strength is above 0.2MPa.
6, long life anti-aging
The service life is more than 50 years, and it is synchronized with the building. Only one insulation construction is needed for a lifetime.
7, good fire integrity
The fire resistance exceeded 3 hours, and the integrity after the fire was good.
8, freeze-thaw resistance
After 25 freeze-thaw experiments, the mass loss rate was less than 5%, the strength loss rate was less than 20%, and the physical and chemical properties were stable.
9, good sound insulation
The sound absorption capacity is 5-7 times that of ordinary concrete, and the sound insulation effect is 60db (140mm).
10, easy to be good
Porous material, can be directly paste, and sticky.
11, low cost
Building insulation costs can be reduced by 3-5 times.
Cement foam insulation board - Product features
Environmental protection, low-carbon new materials, fire performance reached A1 level, solid bonding with concrete, the same expansion coefficient, the same age as the building. For roof insulation board, interior and exterior wall insulation board.
Cement foam insulation board - production raw materials
The best insulation material, advantages: low thermal conductivity, good insulation effect, no burning, waterproof, strong adhesion to the wall, high strength, non-toxic, environmental protection.
Cement foam insulation board - Buy tips
1, see the severity and strength. Thickness/bulk density/compression ratio/binder comprehensive effect is passed, board can pass.
2, see the adhesive selection. Magnesium oxide is used for its good activity, high price, exquisite workmanship and good water resistance.
3, smell the smell. If there is irritating odor, it does not meet the environmental protection requirements.
Editor's summary: The above is the application of cement foam insulation board and the related knowledge of the purchase of skills, I hope to help meet the needs of friends!
