The STEICO internal wall insulation system is a highly effective solution that eliminates the moisture risk associated with IWI.
Use the STEICO internal wall insulation system to provide active moisture control through absorption and redistribution of moisture within a wood fibre board and integral mineral layer.
The system combines the best of modern technological advances with natural, traditional materials; finished with a two-coat lime plaster that perfectly compliments traditional and modern wall finishes.
