The majority of houses built after the 1930’s would have had two walls in their design, the inner walls that shelter the inside, and outer walls primarily in brick.
Between these two walls or “leaves” is a gap of a few inches which acts as an air barrier “similar to a thermal flask” so that the cold and rain from outside will not penetrate the interior causing damp.
Over a decade ago the government promoted cavity wall insulation as part of their energy efficiency campaign and with subsidies pressured energy companies performing installations to meet a certain target or have their energy efficiency certification withdrawn. As a result many works were hurried without the proper survey being carried out or a CIGA (Cavity Insulation Guarantee Agency) certificate provided.
Millions of homes were insulated using either mineral wool fibre, polystyrene balls or expanding foam. In some cases many householders were ill advised and felt obligated to follow suit with others to become ‘greener’ in reducing their energy bills.
Not long after because of bad workmanship many problems began to emerge in these properties such as; condensation, rising damp, dry rot and mould. Materials used were either inadequate or in fact had bridged the gap for moisture to travel across.
Did you know that some of these insulation materials can also be removed and your property restored to its original intention? This is were claims4cavitywall can help.
