ISO-THERM Internal Wall Insulation Membrane 7m²
ISO-THERM Internal Wall Insulation Membrane 7m² is an ultra-thin woven polyester thermal membrane for cold and damp-prone internal surfaces. Its nominal 5mm profile provides thermal conductivity of 0.037 W/mK while remaining vapour permeable and waterproof. This helps reduce heat loss through the treated surface, resist lateral damp transfer and inhibit the formation of surface mould.
Flexible and easy to cut, the membrane is suitable for walls and awkward details where thicker insulation systems can cause unwanted disruption. Once bonded using ISO-THERM BOND PLUS Adhesive 15kg (formerly known as ISO-THERM Superbond Adhesive 15kg), it can be plastered directly to create a conventional decorative finish.
Typical Applications
- Improving thermal comfort on cold internal walls
- Damp wall restoration where a thin, vapour-permeable lining is required
- Helping address condensation and surface mould on cold internal surfaces
Top Tip
"Cut each length to size before starting. Lightly mist the darker side with water, wait around two minutes, then bond the light side to the wall using ISO-THERM BOND PLUS Adhesive 15kg."
