Installation of inappropriate cavity wall insulation in homes will increase the possibility of rainwater entering into the cavity, wetting the insulation, resulting in mould and health issues.
Living in a cold, damp environment can aggravate health problems such as: influenza, strokes and heart disease. Cold, damp homes promote the growth of fungi, mould and dust mites which are linked to asthma and other respiratory conditions. Children are particularly susceptible to the health effects of damp.
Microbes such as mould, fungi and bacteria, discharge spores, cells, fragments and volatile compounds into the air. Exposure to these contaminants is clinically associated with poor respiratory symptoms, allergies, asthma and immunological reactions. Dampness is also linked to being a strong indicator of respiratory symptoms such as cough and wheeze. Children’s education can also be affected. Damp, cold homes can increase the time it takes for them to get over an illness meaning longer absences from school.
Homes with damp, wet, or saturated walls will also cost more to heat. When standard (fibre, bead) insulation materials become wet they lose their thermal benefit, damp walls conduct heat moreso than a dry wall and will increase your heating bills.
Homeowners will also experience the high financial costs of any major remedial work as a result of bad cavity wall insulation (removal of bricks, plaster, redecoration, etc), and the lengthy drying out of their homes for many months afterwards. Many homeowners now instruct their solicitors to seek damages for such related costs.
