Good Repair Guide: Retrofitting wall insulation
Houses built before the late 1970s are unlikely to have any insulation in the walls unless major alterations or renovations have been carried out.
This Good Repair Guide explains options for retrofitting insulation into existing residential timber-framed walls. Insulation materials covered include fibreglass, polyester, wool and mineral wool (and blends of these) and rigid sheets such as polystyrene and PIR/PUR foam.
This guide does not cover blown-in and injected foam insulation or retrofitting insulation to walls where there is no access to the wall framing or solid construction such as concrete block, precast concrete, double-skin brick or solid timber.
