Airtightness Materials: European Origins and Where the Market Stands Today

Like passive house design, airtightness materials originated in Europe — where 100+ brands are now available, and you can find them on hardware store and supermarket shelves. DIY sealing is the norm. In China today, roughly a dozen brands compete — about half imported, half domestic. Across all brands, tech systems vary: ? Self-adhesive vs. sealant-applied ? Plasterable vs. non-plasterable Performance differs. Choose wisely based on your project needs. The gap is clear: ?? In Europe, airtightness materials are standard on nearly every new build — as routine as door hinges. ?? In China, usage is still limited to ultra-low and near-zero energy projects, a small slice of the market.

It's only a matter of time. ? Watch the video to learn more.
