What is the life expectancy of insulating class units?

Insulating glass has a life span of more than 30 years. Insulating glass is made of two (or three) pieces of glass, using high strength and high airtight composite adhesive, the glass sheet and the aluminum alloy frame containing the desiccant. Insulating glass has many advantages over ordinary double-layer glass.

Insulating glass units are affected by environmental factors such as temperature and atmospheric pressure fluctuations, wind loads, working loads, sunlight, water and steam.The service life of sealed hollow glass units depends critically on the perfect function of edge sealing in these environmental conditions.The water vapor permeability of the secondary sealant for insulating glass with a Sealing Machine has little effect on the expected life of double-sealed insulating glass components.because the resistance of edge seal to water vapor diffusion depends almost entirely on the low water vapor permeability PIB primary seal.On the other hand, the viscoelastic properties of hollow glass secondary sealant must be highly valued.

The gas permeability of secondary seal has a great influence on gas leakage rate When filling hollow glass with insulating glass machine.Because the organic primary and secondary sealant permeability is approximately equal.When silicone sealant is used to produce inflatable hollow glass units, additional measures must be taken to ensure airtight edges are sealed.
