About the Curtain Wall Glazing System
A curtain wall glazing system is easy to maintain and repair. Generally, the only maintenance required is cleaning, which should be done non-abrasively to preserve the glazing. The glazing seals will need to be replaced every decade or two for optimal performance. The infrequency of maintenance that is not cleaning makes glazing a very appealing structural feature.
Waterproofing is an important aspect of glazing systems, and it is necessary that there is internal drainage. There are two types of glazing, wet and dry. Dry glazing is a pre-formed rubber gasket, while wet glazing is a wet seal over glazing tape or back-up rods. Wet-glazed systems have better water resistance than dry-glazed, but there are many disadvantages. A wet-glazed curtain wall system must be accessed from the exterior, while dry-glazed can be worked on easily from the interior.
Glazed curtain walls are an attractive, efficient way to let natural daylight into a building while keeping weather out.
