Cavity Wall Insulation can be a great way to keep your home warm and reduce your energy bill if installed correctly. Cavity Wall Insulation carries a number of risks, some of which are set out below:
Slumping Insulation
Some of the first Cavity Wall Insulation employing more rudimentary materials, has now sagged in the cavity wall, leaving cold spots that may be causing condensation. Urea Formal
dehyde
This form of Cavity Wall Insulation was used for a period of time in many thousands of installations. Over time it loses its insulation properties, and in the process can present health risks due to gases which are released as it degrades. Poor Workmanship
Of late, unfortunately, we see many cases of poorly installed Cavity Wall Insulation where the wrong drill pattern or blowing pressure has left cold spots which may lead to condensation. Flood/Water Damaged Insulation
CWI may have been damaged during flooding or through damaged drains allowing water to pe*****te the cavity, soaking the CWI or the property may be located in an area of high exposure to wind driven rain, i.e. coastal or exposed areas. If cavity wall insulation becomes Wet or damp it will transfer moisture to the inner skin of the property, damage wall finishes and potentially cause health hazards. Unsuitable Building Type
A building, or a particular wall, may have been unsuitable for cavity wall insulation in the first place. Examples can be buildings with porous brickwork or mortar; steel and timer framed buildings; or buildings with high exposure to moisture or cavities with mortar/debris present. Main signs of bad Cavity Wall Insulation:
• Dampness
• Mould
• Damp Smell
• Condensation
• Cold Spots
