STEICO internal wall insulation – saving costs, improving the indoor climate

Slim construction, great heating cost savings

STEICO interior insulation is only a few centimetres thick - and yet can improve the energy efficiency of the wall by more than 50%. At the same time, the STEICO solution is particularly safe - because the breathable material prevents mould and moisture damage.
