Low-Rise Curtain Wall Details

Low-Rise Curtain Walls consist of a metal framing system with glass (or similar) glazed into it. The curtain wall system prevents water penetration by sealing out water and draining any water that penetrates out thru channels in the framing members. 

Curtain Walls offer the advantage of being both window and wall systems. The mullion spacing should be arranged to accommodate floor, ceiling and wall intersections. See Thoughts on Curtain Walls.

The key features of the details are the:

• structural bracing for wind loads
• sill flashing to direct any moisture to the exterior
• sound separation at the floor slab
• identifying other components of the wall
• (see the key notes for materials used in this case)
