Ordinary glass can not withstand impact, is easy to break, and the edge is sharp, which is easy to cause harm to human body. Relatively speaking, tempered glass is a better choice. It has strong impact resistance and is not easy to break. Even if it is broken, it will break in the form of particles without acute angles, greatly reducing the harm to human body.

The surface of door and window glass shall be flat and firmly installed without looseness. In case of double-layer glass, the internal and external surfaces shall be clean, there shall be no dust and water vapor in the glass interlayer, and the spacer shall not be tilted.

KDS doors and windows use explosion-proof tempered glass that has passed 3C safety certification. It has high strength, good flatness, purity and no impurities. Its compression resistance reaches grade 9, can withstand wind pressure up to 5000Pa, effectively resist grade 12 hurricanes, and the self explosion rate is relatively low. At the same time, combined with the self-developed hollow anti fog technology and the integrated bending technology of hollow aluminum strip, a fully closed hollow layer is formed to eliminate noise layer by layer and create a quiet and comfortable home space.
