Benefits of using penoTIGHT gaskets around pipe and wire penetrations: 1.Adjustable Fit After Installation penoTIGHT gaskets are made from a flexible EPDM membrane, with different options for all your penetrations airtightness. penoTIGHT 3.5 and 16 provide pre-cut holes and adhesive for a continuous air barrier system. For bigger holes like plumbing penetrations, use penoTIGHT 135 for ease of installation.
penoTIGHT Freedom allows installers to cut holes slightly smaller than the pipe or cable diameter. This creates a tight friction seal while still allowing the penetration to be repositioned after the gasket is in place.
2.Quick Visual Inspection The integrity of the seal is easy to verify by eye, making quality assurance straightforward during or after installation.
3. Penetration Diameter Allowance
penoTIGHT 3.5 - 150 × 150mm sheet that can handle cable diameters up to 8mm
penoTIGHT 16 - 150 × 150mm sheet that can handle conduit diameters from 20 - 30 mm
penoTIGHT 135 - 250 × 250mm sheet that can handle pipe diameters from 150 - 200 mm
penoTIGHT Freedom - 250 × 250mm sheet that allows full customisation by your installer
Installation Tip: Always allow clearance around the penetration to provide room for taping if required. We recommend penoTIGHT 135 and Freedom to be used with our specialised airtight tape yourippa.
If the gasket sits close to a wall, framing element, or service cavity batten, plan the installation sequence accordingly to ensure an unobstructed surface for easy and effective sealing.
