Energy Efficiency and Historic Buildings: Insulation of suspended timber floors
This guidance note provides advice on the methods, materials and risks involved with insulating suspended timber ground floors. The applications described are also appropriate for timber upper floors where there is an unheated space below. Advice is also provided on how suspended floors can be draught-proofed where the installation of insulation may be difficult or potentially damaging to the historic character of the building.
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. Published in 2012.
