As an important material for building energy conservation, aerogel insulation materials have both heat preservation and fireproof performance, which can not only achieve building energy conservation but also protect people's lives and property, and achieve a win-win situation in building energy conservation and fire safety. However, many people do not understand or even have some misunderstandings about the aerogel exterior wall insulation system.
Question 1: What are the advantages of aerogel insulation materials in building insulation and fire protection? What problems should be paid attention to when doing external wall insulation and fire prevention?
Answer: Building fires are terrible things that no one wants to see. The aerogel insulation material itself is a silicate glass fiber inorganic material, non-combustible, thermal insulation, and belongs to Class A fireproof material. When using aerogel fireproof insulation materials, not only can the insulation effect be ensured, but also the fireproof performance can meet the fireproof standards.
Do a good job in the fire prevention of external wall insulation. First, strictly implement various fire protection regulations and strictly implement the fire protection system. The second is to select the insulation materials, do the fire prevention measures in the primary stage of the use of the insulation materials, monitor the construction process at the intermediate stage of the use of the insulation materials, and prevent the occurrence of various fires; after the insulation material is made into the external wall insulation system, Do a proper use of the insulation system and prevent fires.
Question 2: Does the use of aerogel insulation with good thermal conductivity and fire resistance mean that the requirements for tensile strength, water absorption and durability must be reduced?
Answer: Tradematt's high-quality aerogel insulation materials can meet all requirements of tensile strength, water absorption, durability and thermal insulation properties, and belong to Class A non-combustible materials. In most applications, the thermal insulation properties of aerogel insulation far exceed the insulation properties of polystyrene sheets.
Question 3: What is the external wall insulation system? Can aerogel insulation be applied to exterior insulation composite systems?
Answer: The external thermal insulation system refers to a certain fixed method (bonding, mechanical anchoring, spraying, pouring, etc.), and the thermal insulation material with low thermal conductivity (good thermal insulation effect) is fixedly integrated with the wall of the building. An engineering practice that increases the average thermal resistance of a wall to achieve insulation or insulation.
The aerogel outer wall insulation system has the advantages of low thermal conductivity, good gas permeability and high combustion performance level. It can be applied to energy-saving insulation projects of new buildings, expansion and reconstruction of residential buildings and public buildings, including exterior insulation and non-external insulation. Fire curtain insulation for transparent curtain wall insulation and EPS insulation systems. It can be used together with insulation materials whose combustion performance is less than Class A to improve the fire protection function of the external walls of buildings. Aerogel insulation is an excellent thermal insulation product for exterior insulation systems. Not only that, because of its non-combustible properties, aerogel insulation is also a building fire safety solution, which is regarded as the preferred material and solution for high-rise buildings. Program. The flammability of foam insulation products poses a great risk and damage to people and property, so it is not allowed to use this material in high-rise buildings in Europe and America.
Question 4: In Europe, such as Germany, does aerogel insulation only occupy a small market share in all exterior insulation applications?
Answer: In Germany, for high-rise buildings over 22 meters, the market share of aerogel insulation materials in the external thermal insulation composite system is 40%. Aerogel insulation accounts for 5.6% of all exterior insulation systems applications, but this statistic includes the most common buildings in Europe: low-rise single-family homes.
Question 5: What is the difference between aerogel insulation and rock wool?
Answer: Aerogel insulation materials and rock wool belong to different products. The aerogel insulation material is mainly a composite insulation product of a glass fiber blanket substrate and a silica aerogel, which has the characteristics of low thermal conductivity, high strength and long service life.
Question 6: Does aerogel insulation material cause damage to human health?
Answer: Of course not. A number of organizations (eg, the World Health Organization) have conducted extensive research on whether aerogel insulation fibers are carcinogenic, and the results clearly indicate that aerogel insulation fibers are not carcinogens. Carcinogenicity studies of aerogel insulation materials are well known and these studies are publicly available.
Question 7: Does the production process of aerogel insulation materials consume a lot of energy and generate a lot of emissions?
Answer: All or most of the production waste in modern plants is recyclable, and after a small amount of waste is treated, emissions are reduced to a minimum. One unit of aerogel insulation saves hundreds of times more energy in its use than it does in production. Manufacturing 1 kg of aerogel insulation consumes about 20 MJ of energy, while manufacturing 1 kg of polystyrene board consumes at least 85 MJ. The raw materials for making polystyrene sheets are basically fossil fuels such as oil and natural gas, and the aerogel insulation materials only need to use very common gel and glass fiber blankets, and the available reserves are almost unlimited.
