insulation

Spray foam insulation has been used to stop heat escaping from roofs, lofts and attics for decades and comes in two forms.

The work often involves carrying out a heat-loss survey, to spot cold areas that require insulation, and to better understand a property’s heating demand.

The lack of sound insulation was also a regular complaint.

The Grenfell Inquiry's Phase 2 report heavily criticised Celotex for launching a "dishonest scheme to mislead its customers" over the suitability of its insulation for use on high-rise buildings.

A growing number of MPs are concerned about the impact on their constituents of poorly installed insulation, while Citizens Advice is calling on the government to "urgently fix" regulation of the sector.
