Coating the inside of exterior walls is one of the most practical and efficient ways to recover existing buildings, or as a root solution for new projects. Which system to recommend depends on the conditions of the wall and on the intended insulation.
Application with profiles
An auxiliary wall-mounted or freestanding structure can be used. Cover the ‘U’ Studs with acoustic tape and secure them to the floor and ceiling. Make sure they are aligned. Do likewise with the side ‘C’ Studs. Fit the intermediate ‘C’ Studs with the recommended spacing (400 or 600 mm). Put the insulation (Volcalis mineral wool) on the inside, and attach the boards to the profiles.
