Weather Resistant Barriers

Today the building science community and industry professionals understand the cause and effect of proper building enclosure performance on the longevity of the building, tenant and owner comfort, energy consumption, internal air quality, and both initial construction budget and operating costs.  Two approaches for building envelope enclosure are commonly utilized in today’s construction industry – vapour open and vapour closed assemblies. Industry consultants and building professionals are increasingly using a holistic enclosure approach to address a common technical challenge of protecting exterior wall assemblies from air and moisture infiltration while supporting proper wall drying and structural performance. NaturaSeal’s solutions include vapour-permeable barriers that allow controlled moisture transmission and vapour-impermeable barriers that prevent both air and vapour penetration. Together, these systems ensure durable, energy-efficient, and healthy building envelopes tailored to a variety of climates and construction types.
