Estimating the impact of reveals on the transmission heat transfer coefficient of internally insulated solid wall dwellings

摘要

Internal wall insulation as a retrofit measure could help to reduce energy use and greenhouse gas emissions in many of the 6 million solid wall buildings in the UK. However during retrofit, junctions that are hard to deal with are often left uninsulated, increasing heat loss and surface mould growth risk at thermal bridges. Furthermore the effect of junctions, insulated or uninsulated is not properly taken into account in commonly used assessments of heat loss.
