If insulating below a structural floor, insulation can be fixed from below, allowing the floor to be insulated and finished in one process.
In timber frame exposed soffits, insulation is friction-fitted between timber joists, using the whole depth of the joist as an insulation zone. This allows high levels of thermal and acoustic insulation performance.
Our Rock Mineral Wool insulation solutions not only provide thermal and acoustic performance that would be required in an exposed soffit, but are also noncombustible giving additional peace of mind.
