The Blower Door Test is the ultimate judge of a building's performance. Most leaks occur at "penetrations"—where pipes, wires, or windows break the continuous air barrier. To achieve Passive House standards, you need a tape that is both flexible and aggressively sticky.
Sealing Complex Corners and Pipes
When sealing around a pipe penetration, you cannot use a single straight strip. It requires a "radial" approach. The flexibility of our HDPE-backed tape allows it to conform to curved surfaces, while the scrim ensures it won't tear or pull away over time.
Why Width Matters in Window Flashing
For window-to-wall junctions, a standard 50mm tape often provides insufficient overlap. We recommend a 60mm or 100mm width to ensure at least 30mm of coverage on both the window frame and the vapor barrier. This redundancy is what ensures the building stays airtight for its 50+ year lifespan.
Environmentally Responsible Construction
Modern building codes are increasingly focused on indoor air quality. PAC KING PE Airtight Tape uses a solvent-free acrylic system, ensuring low VOC emissions. This is critical for airtight homes where air exchange is strictly controlled via mechanical ventilation.
