Prefabricated Houses and Cavity Wall Insulation
Prefabricated houses – A brief history
Post-war prefabs were built to replace the high levels of dwellings destroyed or damaged during the Second World War. The legal basis for the build of these was outlined in the Temporary Accommodation Act 1944. The prefabricated building project was coordinated by the Ministry of Works, who used the wartime manufacturing and organisation structure to roll out the building project in a military style.
Why prefabricated dwellings are not suitable for cavity wall insulation.
Taking the Tarran Newland prefab design as an example, the walls of these buildings are made up of precast concrete panels approximately 20mm thick. The process for installing cavity wall insulation would be a labour intense and invasive one.
As well as this, the concrete panels are connected using fixing plates which have thermal bridging issues. This means the plates will often transfer heat much quicker than the concrete reducing the overall thermal efficiency of the property.
Overall prefabricated houses are not suitable for cavity wall insulation and cannot be registered for a guarantee, so other methods of insulation such as external wall insulation should be considered.
If you’ve been sold CWI and live in a prefabricated house, your installer should have known that your property was unsuitable and CWI should not have been installed.
If CIGA issued a guarantee, a claim against CIGA may be effective, but more than likely a claim will be made against the installer. If this is the case, a legal professional is best to represent you on this matter as a typical costing quote for rescission and repair could be as much as £25,000
If you’ve got issues of any other nature with your Cavity Wall Insulation that may be down to the installer not following proper guidelines as to the install. 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.
