Guidance on assessing the suitability of existing external cavity walls with masonry and/or concrete leaves for filling with thermal insulants. Does not cover cavity walls exceeding 12 m in height or cavity walls in which vertical members of structural frames bridge the cavity. Does not give guidance on design and construction of buildings intended to incorporate cavity insulation.
