Do you know what mature technologies are used for exterior insulation?
The external wall insulation technology can be divided into two categories: single material and composite exterior wall.
A single material, that is, a single product with good thermal insulation and thermal insulation performance as a wall material meets the requirements of energy-saving standards. Such as aerated concrete blocks, A1C aerated concrete sheets.
Composite wall, that is, composite aerogel insulation material on structural wall. According to the composite method, it can be divided into three types:
(1) Insulation practice, sticking a gas gel insulation blanket on the inside of the outer wall. However, the internal insulation method will form a thermal bridge at the intersection of the inner and outer walls, the ring beam and other parts, and condensation will occur. In the event of a problem, the maintenance will have a greater impact on the household.
(2) Sandwich insulation method, the aerogel insulation material (polyphenyl, rock wool, polyurethane, etc.) is placed in the middle of the wall to form a sandwich cavity. This is the best insulation system for building insulation.
(3) External insulation practice, increase aerogel insulation measures on the outside of the wall. Paste aerogel insulation felt or spray polyurethane on site. The external thermal insulation system is a widely used technology. The thermal insulation efficiency of external thermal insulation is high, does not occupy indoor space, is beneficial to the protection of the main structure, can extend the service life of the house, and is suitable for energy-saving renovation of existing houses.
