FAQS

FAQs (frequently asked questions) about insulation and insulating your home.

Are all external walls suited to having cavity wall insulation installed?

Bonded bead cavity wall insulation can usually be installed in block built cavity walls where there is a free space of at least 40mm.

How do I know if my home is suitable for cavity wall insulation?

If you are unsure if your home is suitable, we can arrange for a surveyor to call and assess your home for suitability. Contact us to arrange an assessment.

How is cavity wall insulation carried out?

The cavity walls are drilled in a specific pattern laid out in the NSAI certification, to ensure all areas of the wall are filled. The insulation beads are blown into the cavity walls with an adhesive, which sets over a number of days. The holes are made good by patching to match the finish of the house.

 

I live in a semi detached house, can I get my walls insulated?

Yes, if the neighbouring house is not getting their cavity walls insulated at the same time as you, then a barrier is fitted in the cavity to prevent the insulation from filling the neighbouring cavities.

It usually takes a few hours to install cavity wall insulation but larger houses may take longer.
