• There are approximately 6.6 million dwellings within the UK constructed earlier than 1919, predominantly constructed with suspended timber ground floors whose thermal efficiency has not been extensively investigated.

This raises questions in regards to the validity of using such fashions in housing inventory fashions to inform retrofit determination-making and house-heating-discount interventions. In an uninsulated ground, the ground joists add additional thermal resistance, but as soon as the ground is insulated , the joists become a thermal bridge compared to the now higher insulated floorboards. Ideally insulation is also put in beneath the joists, particularly within the perimeter region where there are sleeper walls. This could be carried out as a further layer of insulation after insulating in between joists. If you could have an unvented crawlspace or basement, you must insulate the partitions instead of the floor joists.
