Key Performance Less heat loss Lower energy bills Protected building structure Lower temperature fluctuations Fewer damp issues

Product Description

Rock wool insulation board is mainly used for external wall. It is together with the roof, form the envelope of any building, protecting everyone and everything inside. They also cover the largest surface area, making them a prime area for preventing heat loss. The main place where heat is lost is by escaping through poorly insulated walls.
