Thermal mass in lightweight domestic construction

TRADA image

High levels of thermal insulation and airtight fabric in modern residential building has raised concerns that recently built dwellings will have a tendency to overheat during periods of hot weather. Concerns that global warming may cause further rise to UK temperatures in the next 50 years (within the lifetime of these dwellings) would only exacerbate this tendency.

This report which was prepared by the Steel Construction Industry is a summary update of original work undertaken by Oxford Brookes University.

This research summary demonstrates that the risk of overheating in a house built with lightweight framing is comparable to that of a house built to current standards with brick and lightweight block.

Condensation control in dwellingsnavigation-arrow

Condensation in dwellings occurs when warm moist internal air comes into contact with cold inside surfaces, or with cold air or surfaces within the structure.

With improved thermal performance and air tightness in new and existing buildings, the risk of damage from condensation has increased. Most surface condensation...
