Trust Capitol for All Your Construction Barrier Needs

In commercial or residential construction applications, reliable building envelopes – a controlled environment surrounding a structure that provides protection from natural elements – are crucial.

• Air barriers are designed to control or restrict the flow of air between conditioned and unconditioned spaces in your structures. Air barriers also often define pressure boundaries within a building enclosure.
• Water barriers are built specifically to prevent water leakage or penetration from rain or other sources of moisture into your building’s interior spaces
