Understanding Curtain Wall Glazing
There are a variety of different curtain wall glazing or construction materials available for these types of walls.
Curtain walls are much cheaper to build than structural walls, and can spread out across multiple floors. They also expand and contrast with changes in temperature more fluidly when compared to fully structural walls.
Stick systems utilize long vertical and horizontal sticks. The glazing material is then attached to these sticks, piece by piece. Unitized systems are factory fabricated units, that are built to fit your construction needs, and shipped to the construction site.
Glass is the most common glazing material. It offers diverse combinations of color, thickness, strength and opacity. More opaque glass is often used in walls when privacy is a concern. You often see opaque glass curtains on office buildings, or apartment buildings. Transparent glass is used to fulfill an aesthetic design choice.
Stone glazing is most commonly used to add a touch of design diversity to a wall. Generally, a wall will not be made entirely of stone, but will have a few accents spread throughout its face.
Metal panels are perhaps the second most common form of curtain glazing. Panels are the cheapest glazing type on the market. Each panel is made of various types of aluminum pressed into two thin panels. A thin plastic interlayer lies between the sheets of aluminum.
Some curtains use a fabric veneer, as it is less expensive and less permanent. This is perhaps the rarest type of glazing utilized as it tears easily, and is harder to maintain.
