U-value printscreenWhen selecting materials for construction, we should choose good insulators throughout to ensure comfort within the building and low heat energy losses.

We usually calculate a U-value for a particular structure element, eg. a cavity wall, rather than for the individual components that make up that element, eg. block, insulation, air gap, block, etc.

The figure used to demonstrate the element’s resistance to heat loss is called the U-value. It refers to Unit Heat Loss Rate , and its unit is the watt per metre squared per kelvin, W m-2 K-1.

The U-value is defined as the rate at which thermal energy is conducted through unit area, per kelvin temperature difference between its two sides, ie. how much heat will pass through one metre squared of a building element when there is a temperature difference of 1 degree kelvin between the two sides of that building element.

A good insulating structure therefore has a low U-value. Some typical U-values in new buildings today are:

Walls: 0.21

Roofs: 0.16

Floors: 0.21

Contact us today to have a U-value calculated for any part of your structure. We will send you your detailed calculation and report in pdf format.

I contacted Comfort Solutions two years ago about refurbishing an existing converted attic space. Little had been done with it except some minimal bits of insulation and plasterboard in the mid 1990’s. The room was freezing during winter, you could hear the wind whistling through gaps, and it let out... Read more
