Millions face crippling repair costs after botched green upgrades
Cheap-to-fit spray foam cavity wall insulation can cause damp and mould
The insulation material can transfer the water across the cavity to the interior
One expert has estimated that up to two million homes may have problems
Fears the rush to insulate Britain will cause massive damage to properties
Getting Britain's homes insulated is the cornerstone of the Government's green energy policy and an obsession for road-blocking eco-protesters. But the scale of damp-related problems linked to cavity wall insulation is so serious that an MP is calling for an independent inquiry to improve protection for householders.
One expert has estimated that up to two million homes may have problems as a result of insulation being pumped into the cavity between outside and inside walls.
In some extreme cases, the resulting problems of damp and mould inside the house have rendered properties worthless and unsellable.
