DAFA Universal Pipe Grommet – Airtight Sealing for New Builds. The DAFA Universal Pipe Grommet is a patented, high-performance solution for airtight pipe penetrations in new build projects. Part of the DAFA AirStop System, this grommet seals directly onto the vapour barrier, providing a proper seal to prevent air leakage, ensuring thermal efficiency and airtight construction. It meets UK building regulations and Passive House standards, making it an essential component for energy-efficient homes.

Enhance Your Energy Savings
Installing the DAFA Universal Pipe Collar ensures airtight pipe penetrations from day one. By eliminating air leaks, you reduce heat loss and improve overall building performance. Over time, these energy savings translate into lower utility costs, reduced environmental impact, and a more comfortable indoor climate.

Applications
• Residential and commercial new builds for airtight and energy-efficient projects.
• Vapour barrier grommets for continuous airtightness in walls, floors, and roofs.
• Mechanical ventilation systems to eliminate uncontrolled air movement.
• Sealing gaps around windows, doors, and other structural openings.
