Energy Efficiency and Historic Buildings: Draught-proofing windows and doors

Front cover for ENERGY EFFICIENCY IN HISTORIC BUILDINGS: Draught-proofing windows and doors

This guidance provides advice on the principles, risks, materials and methods for improving the thermal performance of existing windows and doors by draught-proofing.

Draught-proofing is one of the most cost effective and least intrusive ways of improving the comfort of occupants and reducing energy used for heating with little or no change in a building's appearance.

The guidance has been produced to help prevent conflicts between energy efficiency requirements in Part L of the Building Regulations and the conservation of historic and traditionally constructed buildings. Much of the advice will also be relevant where thermal upgrading is planned without the specific need to comply with these regulations.
