Why Steel or Timber Framed Properties Should Not Be Insulated with Cavity Wall Insulation
Steel and timber-framed houses should not be insulated with cavity wall insulation. However, few people seem to understand why.
Timber and, surprisingly to many, steel, both need air circulation to prevent rot or corrosion. Many of us will live in houses that have suspended timber floors, and will be aware of the air bricks strategically laid at damp proof course height. These air bricks allow air to circulate underneath the floor joists preventing rot developing and keeping the timbers healthy. The same practice is required inside the cavities of timber and steel-framed houses. Fully insulating the cavity with a retro blown cavity wall insulation product increases the risk of condensation forming and being trapped against the frame. With timber framing, this might lead to wood rot; with steel it will result in corrosion.
There are, thankfully, other ways to insulate a timber or steel framed property very effectively. External wall insulation, for instance, is extremely effective. Internal wall insulation is another option to consider.
If you live in a timber of steel framed property that has been insulated with cavity wall insulation, you will need to have it removed. Over time it may lead to serious structural damage. In addition to the lack of air circulation inside the property, it could also be damaging to your health.

It is now apparent that hundreds of thousands of home owners across the UK will need remedial work that will consist of a full extraction of the Cavity Wall Insulation and could well mean a whole host of other repairs and replacements directly caused by the install, costing in excess of £10,000.
Mortgage lenders are also looking at properties which have had CWI installed and can devalue a property by as much as £30,000 if a valid CWI examination certificate is not available.
