Note
Classification – Airoseal tests were carried out on social housing flats as we felt this was the primary market to be working in and one where there are huge problems in hard to heat streets where older properties have been converted into flats, plus many major cities have high rise buildings that are costly to insulate.

Airoseal has been granted innovative measure status for the duration of CERT. This means the claimable carbon reductions submitted to OFGEM can be given an uplift of 50% of the base carbon reduction figures.
