Building Insulation
China is a large developing country, but also a large construction country, the annual area of new housing up to 1.7-1.8 billion square meters, more than all developed countries each year, the sum of the completed building area. Due to the poor thermal insulation performance of China's building envelope, the total energy consumption of the building in China's total energy consumption in the most share has exceeded 27%. Therefore, if we improve the building envelope heat preservation and insulation performance, the real implementation of “energy-saving buildings, green buildings” policy, is a very important mission.
Current situation
At present, there are many varieties of building insulation materials, mainly divided into organic materials such as polystyrene board, extruded plastic board, polyurethane, etc., and inorganic materials are mainly rock wool. Organic materials have poor flame retardant properties, causing safety hazards to the building itself, while rock wool-based inorganic materials have poor water-repellent properties. At present, the most ideal building thermal insulation material is aerogel thermal insulation felt.
Advantages
1. Aerogel is an inorganic material, class A fireproof;
2. The thermal conductivity is as low as 0.016W/m-k, which can effectively isolate the cold and heat bridge between the building and the outside world and save space;
3. Energy saving and environmental protection, good thermal insulation performance, can significantly reduce energy consumption;
4. Good sound insulation performance, creating a comfortable environment;
5. Aerogel overall hydrophobic, structural stability;
6. Inorganic material, same life as the building;
7. Convenient construction, easy to cut.
