Building Envelope Resilience

The building envelope is a system that meshes multiple elements; structural integrity, moisture control, energy efficiency, and indoor air quality - all rolled up into a single design strategy.

“Moisture has been the number one cause of structural deterioration for as long as there have been structures. Moisture in all its forms—snow and ice, wind-driven rain, water vapor— greatly affect the performance of building materials.” ¹

Since 2001 VaproShield has been committed to keeping the building envelope dry, durable and energy efficient with a highly advanced system of water resistive air barriers and accessories that have been tested and proven to perform by independent third-party labs, and 1000's of projects worldwide. VaproShield membranes are the single source solution to manage water and air leading to energy conservation and savings for the life of the building.

  • Studies show a 10-40% energy savings can be directly attributed to a properly installed continuous air barrier system.
  • The US Dept of Energy states “Indoor comfort, and energy management is enhanced by managing air infiltration.”
  • VaproShield membranes offer an unimpeded drainage plane (no horizontal tape reverse laps)
  • Windows are detailed with monolithic liquid flashing offering the best protection for the #1 leak area
  • Resulting in: a DRYER and more DURABLE building with healthier indoor air quality (IAQ)
