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. Insulating other building elements is likely to produce greater benefits in energy efficiency for significantly less cost. This is partly because a typical solid floor already provides a degree of insulation, but mainly because the ground beneath maintains a stable temperature of around 10 degrees C. However, where an existing floor is being taken up, replaced or repaired, then it can be worth making use of the opportunity to improve thermal performance.
Insulation Of Suspended Timber Floors
Suspended timber ground floors can be a source of considerable heat loss from older buildings, particularly where there are gaps between floorboards that create draughts. Insulating and draught-proofing floors can make an important contribution to reducing fuel bills and carbon emissions.
