Air Vapour Barrier Systems

What are Air Vapour Barrier Systems?
Air Barriers control air leakage into and out of the building envelope. An effective Air Vapour Barrier System literally wraps the base of the structure and ensures that it is protected from the effects of air leakage. Air quality and conditioning, such as humidity levels, are often a major concern among prospect customers.

Improper envelope air leakage can result in reduced thermal comfort leading to higher energy costs, degraded indoor air quality, and mould. Mould and mildew fungi usually grow in dark, damp areas. Excessive moisture can create a breeding ground for insects and mould. Undetected mould and fungus is a potential health hazard and can contribute to chronic colds and respiratory conditions. Luckily, all of these effects can be resolved by applying a proper Air Vapour Barrier around the building envelope.

The Air Vapour Barrier is installed in either one of two-ways:

  • Fluid-Applied – similar to those used in roofing applications, they roll or brush on as a liquid and cure to form a seamless membrane.
  • Sheet-Applied – also similar to those used on roofs, including single-ply thermoplastics and rubberized asphalts.
Signs of Potential Water Problems Include:

  • Stains or Rust on Concrete
  • Damp Spots
  • Cracked Walls
  • Blisters or Peeling Paint
  • Warped Paneling
  • Wall Movement
  • Water Seepage
  • Mould or Mildew
