Code of practice for stabilization and thermal insulation of cavity walls (with masonry or concrete inner and outer leaves) by filling with polyurethane (PUR) foam systems
What is BS 7456 - Cavity walls filled with polyurethane (PUR) foam systems about?
BS 7456 gives recommendations for the installation of rigid polyurethane (PUR) foam systems complying with BS 7457:1994 , which are dispensed on-site, to fill cavities of the maximum width of 150 mm of suitably constructed external walls of maximum continuous cavity height of 12 m which have masonry or concrete inner and outer leaves, thereby providing additional thermal insulation to such walls and simultaneously, especially in the case of walls with damaged wall ties, improving their structural integrity. Note: Walls built of random rubble are not covered by this code.
