What are U-values?

The term “U-value” refers to the rate of transfer of heat through a structure divided by the difference in temperature across that structure.

Simply put, the better-insulated a structure is, the lower the U-value will be.

If insulation is fitted poorly, with gaps and cold bridges, then the U-value can be considerably higher than desired.
