Aerogel insulation felt for use in low energy buildings
1. Thermal insulation wall
The metal sandwich panel is widely used as a wall body, and the metal sandwich panel is formed by injecting a flame-retardant aerogel insulating felt material into the middle of a 2-layer metal panel. The aerogel insulation felt is directly filled into the cavity between the inner and outer walls. It can also directly cover 10mm thick aerogel insulation blanket on the outside of the brick wall, and use special cement to coat the surface with polymer cement or color coating and mortar. The technology is simple and durable. The metal sandwich panel has the advantages of light weight, heat insulation, waterproof, decoration, etc., and is convenient to install and has a high construction speed, and has good effects as a wall insulation material. In addition to metal, it may be a plastic sheet, an asphalt-impregnated kraft paper, a glass fiber fabric, an aluminum foil, or the like.
2. Insulation roof
For flat roof structures, there are basically two ways to keep warm: one is to lay aerogel insulation blanket on the roof, which is more common in Japan; the other is to use aerogel insulation felt directly on the roof. The methods are widely used in Europe and the United States and China. The roof aerogel insulation felt insulation layer is generally composed of an aerogel insulation blanket and a protective layer. The main purpose is to directly cover a layer of aerogel insulation felt material on a clean and dry roof base layer, and then add a protective layer thereon to protect the aerogel insulation felt from direct sunlight and reduce external weathering. Improve the rigidity and weather resistance of the roof. For the glass roof, the aerogel insulation blanket is placed above the eaves to block the thermal bridge.
3. Insulation doors and windows
There are two main forms of aerogel insulation felt applied to insulation doors and windows. The aerogel insulation felt is used as the frame of the window frame, and the heat preservation performance can reach more than 2 times of the wooden frame window; the aerogel insulation felt can also be used for heat insulation and waterproofing of the door frame and the window frame.
4. Ground insulation
Generally, a 10mm thick aerogel insulation blanket is laid on the ground or an aerogel insulation blanket is laid under the indoor floor of the house to improve the indoor insulation effect.
At present, high-performance aerogel insulation felts have fewer building materials. Joda has developed a high-quality aerogel insulation felt building energy-saving sheet, which has the following characteristics: (1) Flame-retardant products, this type of gas condensation The rubber insulation blanket is made of high flame retardant supercritical aerogel;
(2) Environmentally friendly products, aerogel insulation felts are completely supercritical extraction and drying processes in the production process;
(3) Diversified products, aerogel insulation blankets are glass fiber or ceramic fiber composite materials, which can be replaced according to different needs of customers. The insulation and decoration functions of the thermal insulation exterior wall can be integrated.
