Masonry External Wall Insulation Details

The details within this section have been developed for a range of externally insulated solid masonry wall constructions.

For this form of construction, details are given for the junctions with a range of roof, ground floor and internal floor types, in addition to details around the window openings etc.

Insulation thickness for main building elements have not been provided as these depend on the thermal properties of the materials chosen, together with the proposed U-value.

All details are shown with a thin coat render system for simplification. However, a range of cladding may be used without any loss of thermal performance or increased technical risk. These include thick coat renders, brick slips, tile hanging, and other proprietary systems. It is recommended that insulating and cladding components are part of a system to ensure compatibility.
