Cavity Wall Insulation Extraction
Utilising professional tools and machinery, Environmental Protective Coatings can remove defective cavity wall insulation, creating very little disturbance to the fabric of the property or to the occupant of the home. Environmental Protective Coatings can carry out the extraction of Rockwool, White wool, foam and bead insulation products from the cavity walls of residential and commercial properties throughout the UK.

This cavity wall extraction process is conducted for many reasons including:
Defective insulation materials (such as Urea-formaldehyde) can break-down and generate dangerous chemicals. Early foam insulation had this risk and was not protected by the same rigorous BBA certification licences or given the same 30 year guarantee through the Cavity Insulation Guarantee Agency (CIGA) as present day insulation materials.
The cavity insulation gets moist, which breaks down the qualities of the insulation. This can transpire because of a number of reasons such as flooding, porous brickwork or mortar, or via a burst water pipe in the loft.
Poorly set up cavity wall insulation, installed with the wrong drilling pattern or at the wrong thickness can bring about damp and condensation problems.
Thermal Wall Coating
Virtually 45% of the all the heat in your house is seeping through your walls. The reason for the prodigious amount of heat loss through your walls is due to the moisture that finds it way from the outside in. Our masonry clear thermal coating can eliminate this by chemically bonding with the surface and creating an invisible insulation barrier. Our dirt resistant emulsion can also create this barrier for rendered houses while at the same time protecting against all types of weathering and decay.
THE PROCESS; The Way Cavity Wall Insulation Extraction Works
Cut a brick out at the base of the property using an arbortech allsaw. This professional tool means we can save the original bricks so we can place them back in when we’re done.
Drill the current insulation injection openings out but only using a 14mm hole not the regular 22mm. (Additional holes may be necessary above glass windows since this is a trap area for the insulation).
An extra row, 3 bricks on top of the damp proof course (D.P.C) is also needed to make sure all cavity wall fill is forced towards – and sucked out by – the hoover, ensuring no insulation remains above the D.P.C.
Starting off at the first hole, closest to the industrial Hoover (from where the brick was removed), we use compressed air to push the insulation towards the hoover. This makes a gap in the insulation allowing the material to be sucked out. We then move a level above, to push the subsequent section to the gap below and continue to repeat the process, pushing all the insulation downwards and out via our extraction hoover.
The extracted material is bagged on-site and taken away under a waste carrier’s license
The home is then inspected with a boroscope to ensure the cavity wall insulation is removed. A specialist attachment could also be used to link the boroscope to an iPhone. This allows us to take photos and video clips of the inside of the cavity, which then makes it possible for our customers to properly examine our job, and make sure all insulation is eliminated for themselves. These pictures and videos may be retained for you records.
All flues, chimneys and gas vents are examined by a competent & accredited person. For more information or a free quotation for cavity wall insulation extraction Wirral please contact our team today.
