Insulation Thermal Imaging Surveys, UK

Virtually every building in the UK could have its insulation improved. Building Regulations state levels that a new building should achieve, old buildings don’t. That is a fact. However, we at Thermal Innovations Ltd have found through our insulation thermal imaging surveys that the biggest problem with newer properties is not that the wrong materials have been used but, that the workmanship in installing the specified insulation leaves a lot to be desired. This is also the case in older properties that have had insulation retrofitted to improve the thermal performance.

Here are a few examples of the correct insulation being used but show that poor installation negates a large proportion of the benefits that should be achieved.

Through one of our insulation thermal imaging surveys, we found the insulation was of the correct thickness but had not been properly installed to the eaves. The air from the eave vents had moved the insulation to allow a cold chimney to be created. Installing eave baffles and placing the insulation to the correct position has been shown to have a dramatic effect on the room temperature.

Before Insulation
After Insulation

N.B. Heat always moves from hot to cold. That is one of those Physics facts. Therefore the heat in this room is being drawn from the air to the cold ceiling areas and out of the room. These cold areas also have the added potential of creating areas where air humidity will condense and cause mould patches over time.

Below is an example of underfloor insulation using the new high tech reflective Foil type

This type of insulation needs an air gap to be effective. Through one of our insulation thermal imaging surveys, we found this was installed incorrectly. It can be seen that we want to see cold areas as this means heat is not escaping into the cavity under the floors. If the gap of 50mm was created during installation then this would perform as specified. As it was not the insulation was useless at achieving the Regulated U-Value.

Insulation sagged - has slight gap to flooring (point 2)
Insulation against flooring - no gap (point 3)
Temp changes between positions show why an air gap is needed to stop heat loss i.e. gap needed to achieve U-values
