Video details

To improve airtightness, first know which materials are airtight — and which aren't. Airtight materials form the building's air barrier: concrete, plaster, steel, glass, and quality doors & windows. The weak points? The joints between them. Many conventional buildings use expanding foam to seal these gaps. Problem is: ❌ Can't guarantee full fill during installation ❌ Shrinks and cracks over time Foam alone cannot be relied on as an airtight seal. For ultra-low energy buildings, proper airtightness requires dedicated airtight membranes and sealing tapes — engineered to stay tight for the life of the building. ? Watch the video to learn more.
