Ask any Passive House expert like Passivhaus Institute (PHI) standards, and they will tell you: a building can have the thickest insulation in the world, but if its Airtightness is compromised, the energy balance fails. In high-performance envelopes, air leakage is not just about heat loss; it’s about preventing interstitial condensation and protecting the structural integrity of the building. For architects using Vacuum Insulation Panels (VIP), the challenge is twofold: achieving the world's lowest thermal conductivity (0.002 W/m·K) while ensuring the envelope remains a perfectly sealed "thermal skin."
At Hebei Woqin, we recognize that insulation is only as good as its seal. Our VIP systems are engineered to be the primary defenders of your building's airtightness:
Customized Staggered Joint (CSJ) Technology: Standard butt joints are a nightmare for both thermal bridging and air infiltration. Our customized staggered joint VIPs allow panels to overlap and interlock. This creates a labyrinth seal that makes it significantly easier for installers to achieve the required n50 ≤0.6h⁻¹ pressure test results.
Vapor-Tight Barrier Films: Our multi-layer high-barrier envelopes don't just protect the vacuum; they serve as an ultimate vapor and air barrier. By reducing the number of joints through customized large-format panels, we minimize the potential points of air leakage.
Compatibility with Passive House Tapes: We’ve tested our panel surfaces to ensure maximum adhesion with industry-standard airtightness tapes and membranes. When you use Woqin VIPs, you are building a continuous, uninterrupted barrier against the elements.
For projects in challenging climates—from the wind-swept coasts of Canada to the humid summers of New York—airtightness is what prevents moisture-related mold and keeps indoor air quality pristine. Woqin’s VIPs offer the ultimate "Two-in-One" solution: the thinnest profile for maximum space and the most robust seal for maximum airtightness.
At Hebei Woqin Trading Co., Ltd., we don't just sell panels; we safeguard the energy integrity of your vision.
