No other manufacturer can offer you a more diverse and comprehensive list of air barrier, waterproofing, and roofing products to suit your specific building design requirements.

The Building Envelope is essentially the "skin" of a building. The quality of the Building Envelope will determine how well a building will function and its life span.

The requirements of the Building Envelope will differ with the climate of the area. In areas where insulation is necessary the following requirements have been identified by Dr. Neil Hutcheon in the Canadian Building Digest - CBD48 (1963).

   • control heat flow
   • control air flow
   • control water vapor flow
   • control rain penetration
   • control light, solar, and other radiation
   • control noise
   • control fire
   • provide strength and rigidity
   • be durable
   • be aesthetically pleasing
   • be economical

Examination of building problems clearly indicates that the requirements of the Building Envelope most in need of solutions are air flow, water vapor flow, rain penetration, and durability.

Building Envelope failures are evident as rain penetration, high energy costs, early deterioration of building components, and Sick Building Syndrome/Indoor Air Quality (IAQ) problems.

At Henry we understand the principles of providing integrated systems, with our high quality products, to ensure superior building performance. This translates into Henry Air Barriers, Waterproofing and Roofing systems and the expertise to integrate these systems.
