Energy efficiency and historic buildings: insulating dormer windows
This guidance note provides advice on the principles, risks, materials and methods for insulating dormer windows. Dormers come in a large variety of shapes, sizes and materials and can be a particularly difficult element to insulate. However, if insulation is omitted or is poorly detailed then the energy performance of the whole roof can be compromised.
