What is Cavity Wall Insulation?
A cavity wall is a pair of walls with a gap in-between. These are found on houses generally built in the 1960s onwards. The insulation that we use is called "thermabead", small beads that are inserted into the cavity under high pressure to maintain heat within a home.


How does it work?
Small holes are drilled into the outside layer of a cavity wall.
This allows a tube to be inserted and the insulation is blown inside. This insulation, thermabead, fills all the cracks to make sure that there is no place left in the cavity.
Frequently Asked Questions
Does it cause damp?
No- when installed correctly, cavity wall insulation does not cause damp issues. To make sure this doesn't happen, we ensure that sufficient ventilation is installed.
How long does cavity wall insulation last?
The life expectancy of the insulation is 25 years. However, there are many examples of where the insulation has lasted longer than this.
Are we able to replace cavity wall insulation?
We are able to replace cavity wall insulation if the cavity is fully empty. When we do a survey of the property, we will check to see if there is any insulation in the wall. We are not able to provide a cavity extraction service.
