The insulated glass is a prefabricated unit made of two or more glass panes with aluminum or stainless steel spacers filled with desiccant, which are edge-sealed with compound sealant (butyl, polysulfide or structural sealant).

The variety of IGU can be achieved by applying spacers of black, white, gray etc and sealant of same color.

Features:

Performance:

Optical performance: Visible LT 10-80% and LR 13-35% depends on different panes of IGU.

Thermal feature: IGU can reduce U value, esp. when filled with inert gas.

Sound insulation: IGU can lower the noise. If applied with laminated pane, 80 decibels of the traffic noise could be as low as 45 decibels.

Sealing feature: Aluminum spacer is bendable and minimize the joints; dual sealing keeps the air-tightness and life of IGU.

Due resistance: Desiccant keeps the dryness inside the spacer and resists forming of due.

Processing limit:

Max size: 2400×4500mm

Min size: 200×300 mm

Max thickness: 60mm

Spacer width: 6mm,9mm,12mm,15mm,18mm etc.
