The control of condensation to within safe limits is an important consideration in the design and construction of buildings.
If left unmanaged, vapour produced by building occupants can have a detrimental effect upon the wooden and metal elements of a building and can reduce the thermal effectiveness of insulating materials.
Here at Graysons, we supply the complete range of Visqueen vapour control layers, which can be installed to effectively restrict the passage of warm, moist air within floor, wall, and roof constructions.
