TIGHTPlate™ is a flexible foam gasketing strip that can help reduce air infiltration between a concrete slab foundation and bottom plate. The closed-cell polyethylene (PE) foam compresses to seal gaps in irregular surfaces, helping reduce air leakage for a tighter building envelope and enhanced energy savings. It provides excellent and enduring resistance to water and water vapor, as well as preventing pests from entering the building.
Benefits:
- Creates an air tight gasket seal between uneven surface of concrete slab and bottom plate of external wall - to improve energy efficiency of building (refer to section detail drawing below)
- Easy to install using staples
- Prevents entry of pests into finished building
- Provides a moisture barrier to bottom plate
-
Comes in two widths:
- 100mm x 15m x 4mm
- 150mm x 15m x 4mm
- Made in Australia
-

$15 per roll for 100mm size and

Purchased this product after watching YouTube video explaining how to construct airtight wall (highly recommend all EM construction videos). Used the 150mm product on 90mm depth external walls (wrapped up external side and fastened with strip of OSB) and the 100mm for internal walls that are also 90mm depth (no need to trim, excess 5mm each side will be hidden by wall lining). Certifier was impressed at our framing inspection!
Essential for an airtight seal along your bottom plate. The 150mm length allows for weapping up the wall so you can tape/connect to an airtight building wrap
