WHY REMOVE CAVITY WALL INSULATION:

  • Poorly installed mineral wool or fibre type insulation can sink in the cavity and with time may become moist or damp. With time the insulation property of such material can be greatly reduced and even start to have a negative effect.If you imagine the annology of a man working outside wearing a t-shirt. If his shirt was to be wet the body heat would be absorbed by water in the shirt and the man maybe warmer with no shirt at all.As the wet shirt is keeping him cold. The same thing can happen with the fabric of your home.
  • Defective insulation material (such as Urea-formaldehyde) can break-down and release toxic gasses.
  • Poorly installed cavity wall insulation, installed with an incorrect drilling pattern or at the wrong density can result in damp and condensation issues.


How is old insulation Removed?

The redundant cavity wall insulation is removed using an industrial vacuum , Small holes similar to those used to installing insulation are drilled and high pressure directional air is used to drive old insulation to extraction points. The same holes are used again for installing the new silver bonded beads but only once the cavity has been inspected and seen to be completely clear.

Redundant insulation is automatically bagged by the vaccum .Which is then removed and disposed of.
