Ultrotherm Insulation
About This Project

Insulating older properties without cavity walls has proved to be a problem. External insulation systems are expensive to install while internal insulation systems have not been desirable for a number of reasons including adjustments to fixtures and fittings, loss of valuable space and the considerable disruption involved. Ultrotherm internal insulation system offers a solution that addresses these problems.

Cold wall surfaces attract condensation and mould, particularly where ventilation is restricted such as behind furnishings and in corners. Application of 12mm Ultrotherm increases the surface temperature of the walls, preventing the attraction of surface moisture that leads to condensation problems and mould growth. Rooms that are uncomfortably cold become warmer and more welcoming. We offer a 10-year guarantee on the installation of Ultrotherm insulation.
