3, waterproof sealing material
Waterproof material is an important functional material needed by construction industry and other related industries, and an important part of building materials industry. With the rapid development of China's national economy, industrial buildings and civil buildings put forward a variety of high-quality requirements for waterproof materials.
4, energy-saving doors and windows and energy-saving glass
Building doors and windows and building curtain walls are the components of building envelope, the most active and sensitive parts of building heat exchange and heat conduction, and the heat loss of the wall is 5-6 times. The energy saving of doors, windows and curtain walls accounts for about 40% of building energy saving, which has an important position.
