ISO-THERM Installation FAQs
Do I need to prepare the wall before applying ISO-THERM?
Yes. The surface should be clean, sound and free from dust, loose material and contaminants. Any underlying damp issues should be identified and addressed before installation.
What adhesive should I use with ISO-THERM?
Use the recommended ISO-THERM adhesive for correct bonding and performance. Follow the product guidance for coverage rates, open time and curing before finishing.
Can ISO-THERM help reduce condensation and damp?
ISO-THERM is commonly used to improve internal wall insulation and reduce cold surface areas that contribute to condensation. Always assess the cause of damp, improve ventilation where needed and follow best-practice installation methods.
Can I install ISO-THERM on painted or plastered walls?
It depends on the condition and adhesion of the existing surface. Loose, flaking or unstable coatings should be removed and the substrate made sound. If you're unsure, call our technical team for advice.
