Description
A wall cap is a protective cover that is installed at the top of an exterior wall to help prevent the entry of rainwater, debris, and other potential contaminants into the building. These caps are typically made from a durable, weather-resistant material such as Galvanized or Galvalume metal, and they can come in a range of different shapes and sizes to accommodate the specific needs of the building. The primary purpose of a wall cap is to provide a barrier against moisture and other potential sources of damage to the building’s exterior walls. Without a proper wall cap, rainwater can collect on the top of the wall and seep into the building, potentially causing a range of problems including water damage, mold growth, and structural issues.
Frequently Asked Questions
How do Wall Caps limit water entry?
Wall Caps shield exterior duct openings from direct rain while preserving the intended intake or exhaust airflow.
Should I use galvanized or Zincalume for Wall Caps?
For Wall Caps, galvanized steel is the general-purpose choice; Zincalume holds up longer where salt air or constant damp is a factor.
What terminates an intake or exhaust duct at an exterior wall?
Wall caps terminate exterior intake or exhaust ducts while helping block rain, debris, and pests from entering the opening.
Which metals do you make Wall Caps in?
