Curtain Wall glazing is an Economic way of providing a glazed Facade to the building . It allows modern insulating glass unit to control internal temperature while allowing natural light to penetrate deep inside the Building.
GLASS CURTAIN SYSTEM TYPES :
- Pressure Equalizer rain screen systems are the best if you need a system to resist air and water infiltration. A gasket surrounds the face of the glass and creates a pressure equalized chamber that forms an airtight barrier. The outside face of the glass and accompanying exterior glazing materials with the aluminum framing create a rain screen, and shed water away. These systems also do a fair job of transferring wind loads.
- Water Managed systems incorporate drains and weeps. These systems are designed to resist water infiltration, but they make no effort to create an air barrier or “zone-glaze”. As a result, the pressure differential between the glazing pocket and the interior may be strong enough to force water vertically higher than interior gaskets.
- Face Sealed systems require continuous and perfect seals between each glass unit, it’s frame and between all other frame members. The long-term durability of these seals is minimal.
