FAQs

As a company, we are asked many questions including ‘what is cavity wall insulation’ and ‘can cavity wall insulation be removed‘. Here, you will find some of the most common questions answered by our team of experts.

 

What is cavity wall insulation?

Both residential and commercial properties built after the 1920’s typically have cavity walls. The cavity prevents water and humidity from filtering into the house, and insulating materials can be fitted into the space between the outer and inner walls.

One of the questions we are mostly asked is ‘what is cavity wall insulation’. Cavity wall insulation is used to reduce heat loss through the cavity wall by filling the air space with a porous material, immobilising the air trapped in the space and therefore supposedly preventing convection and ensuring greater warmth inside the property, reducing energy costs and usage. It also claims to keep buildings at an even temperature and help prevent condensation on walls and ceilings. If you’re still asking yourself what is cavity wall insulation, allow us to clear things up for you by getting in touch with us.

The cavity is typically filled with mineral wool, beads or granules, or formed insulants, and is installed by drilling a pattern of holes into the outer skin of the building before the chosen insulating material is blown into the cavity until no space is left. When poorly installed, people begin to experience a number of cavity wall insulation problems, but can cavity wall insulation be removed? This is where we come in with our unique extraction service.

Why does cavity wall insulation need to be extracted and can cavity wall insulation be removed?

Cavity Care Solutions have informed us that their customers’ reasons for having cavity wall insulation extraction are varied with some reasons being problems with cavity wall insulation. The length of time between the original installation and subsequent extraction is also varied. This clearly demonstrates a wide ranging and continuing requirement for use of the patented method. In addition to this, where cavity wall insulation has been appropriately and correctly fitted, it has a life span of approximately twenty-five years. This also represents a potentially large – and growing customer base outside that which focuses on the CWI having been incorrectly and/or inappropriately installed. People tend to ask us how to remove wall insulation. If you would like to know more about the extraditing process, please don’t hesitate to get in touch with us.

Uncertainty surrounding the longevity of cavity wall insulation?

There is also the question of the longevity of the system, even where is has been installed correctly and appropriately. CIGA offer a guarantee lasting 25 years for cavity wall insulation installation. However, this raises the question of the efficacy of the product after 25 years, and whether it will require removal and replacement. Should this indeed be the case, the potential for an on-going and long-term requirement for the cavity wall insulation extraction as offered via our Client’s patented method is huge. In almost all cases, regardless of the quality of the insulation, cavity wall insulation problems can and probably will arise.
