Experts Say, Cavity Wall Insulation May Cause Damp and Other Problems

Cavity wall insulation can reduce heating bills but it may sometimes cause problems.

Extract Insulation Ltd are based in Hampshire, the company specialises in the removal of cavity wall and loft insulation across England and Wales. Extract Insulation Ltd can remove problem expanded polystyrene, loose or bonded urea formaldehyde, Rockwool and Whitewool mineral fibre insulation.

On their cavity wall insulation removal page Extract Insulation Ltd say, “As we only specialise in removing the insulation and not installing it, we offer a solely independent view on cavity wall insulation as this is our main focus.”

Masonry bricks are very porous, the purpose of the cavity wall is to allow moisture to drain but it can also let out a lot of heat making insulation of the cavity popular. Cavity wall insulation is injected into the space or cavity between the outer and inner wall of a property, this cavity is between 50mm and 300mm thick. Injecting insulation into this cavity can reduce heating bills because it reduces heat loss by up to 35%, cavity wall insulation can also keep properties cooler in the summer months. Insulation keeps warm air in and hot air out, it is considered one of the most cost effective ways to reduce heating bills.

All UK properties built after 1920 will probably have cavity walls, if the thickness of a wall is 260mm or more there is a strong chance the wall has a cavity in it. In the 1990's building regulations made it compulsory to inject insulation into the cavity wall of new build properties.

Decayed or incorrectly installed insulation can cause problems, damp problems may also occur if the wall is exposed to heavy rain, the damp proof course is covered by external ground or if the wall has cracks in the rendering. Extract Insulation Ltd give a full guide to the insulation extraction process on their website, the company have recently published a blog post further detailing the cavity wall insulation problems they see regularly.

All of Extract Insulation Ltd's operatives have ten or more years experience in the installation and extraction of insulation, the company's operatives can also carry out basic gas/fossil fuel appliance checks before and after any extraction works. Extract Insulation Ltd say this is only mandatory for insulation installation but they believe it should be mandatory for extraction too.
