Landvac tempered vacuum glazing can last more than 25 years because it has a special edge sealing technology that ensures the stability and durability of the vacuum cavity. The edge sealing material can withstand high temperature, humidity, and pressure changes. The edge sealing process is done with strict quality control, which ensures the reliability and safety of the product.

Landvac vacuum glazing is a type of tempered vacuum insulated glass that has a very low thermal conductivity and a high resistance to heat transfer. It consists of two layers of tempered glass separated by a vacuum cavity, which prevents the convection and conduction of heat. The vacuum chamber also reduces the sound transmission and the condensation on the glass surface.
