Air Tightness Products

High-performance buildings must be virtually airtight. And, Passive House buildings are among the greenest and most sustainable buildings in the world in part because they are designed and built for exceptional airtightness. That’s a huge difference from conventional buildings where airtightness is often an afterthought or a lucky accident.   

Airtightness is difficult and painstaking to achieve with conventional building products, but it’s relatively easy to achieve with a combination of proper design, attention, and high-performance components.
