Technitherm Cavity Wall Insulation FAQs

What type of material is used in Technitherm insulation?

Technitherm insulation consists of a foam substance which is widely referred to as polyurethane. It has the ability to bond to almost any material and is completely water resistant. When the foam is injected, it starts off as a fluid, but quickly expands and hardens to completely fill the cavity and bond the inner and outer walls together.

How will I know if my home is suitable?

Technitherm works in homes that are not suitable for standard cavity wall insulation. It effectively fills narrow cavities from >50mm, random stone walls, variable width cavities and high rise Hard to Treat properties. One of our experienced surveyors will conduct a detailed technical survey to ensure your property is suitable.

How long does it take to install Technitherm Insulation?

Technitherm insulation is inserted from the outside of the house with minimum disruption. For the average property, it takes roughly one day to install.

What guarantee does Technitherm insulation offer?

Technitherm insulation is approved by the British Board of Agreement (BBA) and comes with a 25 year manufacturer’s guarantee which has been officially recognised by the industry regulator Ofgem.

Will Technitherm insulation cause any damage to my property?

To enable your cavity walls to be insulated, a series of small holes are drilled into the brick work. After the insulation has been installed the holes are filled using colour matching mortar.
