Weather Barrier Systems

Custom Drywall has been performing air and vapor barrier installation since 2010. After years of installation, we understand the importance of these systems to efficiently protect buildings from the harmful effects of air and moisture.


Air and vapor barrier provides an effective barrier against air exfiltration and infiltration. It reduces condensation within the wall cavity/wall assembly and increases efficiency of building mechanical systems.

There are two types of air and vapor barriers: vapor permeable and non- permeable. The two installation types are sheet applied-self adhering and spray applied liquid. Substrates include:

  • Gypsum sheathing
  • Concrete block (masonry)
  • Cast-in-place (CIP)
  • Precast concrete
  • Plywood
  • Steel

Weather barriers prevent the passage of moisture, rain, and wind through critical areas of walls. It also helps protect building materials from deterioration. Tyvek Commercial Wrap is a product used to help improve long-term building performance.
