Energy Efficiency and Historic Buildings: Insulating solid ground floors
This guidance note provides advice on the methods, materials and risks involved with insulating solid ground floors. The energy saving resulting from insulating solid ground floors can in many cases be of marginal benefit when the cost and disruption to the building fabric are considered. However, where an existing floor is being taken up, replaced or repaired then it can be worth making use of the opportunity to improve the thermal performance.
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.
