Get rid of cold walls with NW Damp & Mould Specialists

At NW Damp & Mould Specialists, we are always on the lookout to improve the way we can install products.  

Here we have a new and innovative patented textile-based thermal insulation system for wall insulation, damp control, and surface mould prevention — designed to deliver dry and warm walls.

ISO-THERM is an ultra-thin (+/-4mm), specially woven polyester-based material, which is both unique and patented.

Available in 1-metre-wide rolls, it is flexible, lightweight, and ideal for use in a wide variety of insulation applications and wall finishes.

Due to its ease of use and flexibility, it can be cut around light switches, sockets, radiator brackets, and similar fittings. Its minimally invasive installation means door architraves and skirtings can often remain in place. Thanks to its malleability, it easily fits around and into window reveals.

ISO-THERM is affixed using our unique ISO-THERM adhesive, typically trowelled onto the wall to a thickness of approximately 5mm. With ISO-THERM embedded and rolled into the adhesive, and finished with a direct plaster skim coat, the final insulation depth is around 10mm.

Crucially, ISO-THERM is vapour permeable yet waterproof, resisting lateral damp transference and preventing the build-up of natural surface salts like nitrates and chlorides — key contributors to unsightly efflorescence and mould growth.

Due to its superior thermal efficiency and moisture management properties, ISO-THERM offers exceptional protection against surface mould, making it an ideal insulation solution for both renovation and repair projects.
