Cavity wall insulation was not regulated before 1995. Cavity wall insulation could have been poorly installed due to this. This could lead to dampness or condensation problems if the density and drilling pattern are incorrect.
Cavity wall insulation can last for a lifetime when installed correctly and maintained at a high standard. Older materials might be less efficient than newer materials. We can remove old insulation and install EPS Bonded beads. After the old insulation is removed, the cavity walls will be conditioned to receive the new insulation. You might also qualify for cavity wall insulation removal grants.

 

It has been shown that extreme weather conditions are getting more severe every year over the years. Buildings that have been using older insulation techniques can become uninhabitable. Water penetration can cause insulation to become wet. This can lead to insulation becoming wet and retaining moisture. Insulation can become dampened if moisture seeps through walls.

 

It can be caused by many things, including:
  • High-exposure areas or in severe zones are not recommended for property.
  • Badly installed insulation could lead to voids that can lead to cold spots and condensation.
  • Capillary action can be caused by capillary action if a cavity isn’t cleaned up before insulation is installed
  • Incorrect insulation density
  • Too little cavity for capillary action
  • Porous mortar joints/mortar joints, and/or poor render conditions allow moisture ingress
  • Flood, fire, subsidence, and escape of water.
  • Cavity Blockages
You can fill the cavity by adding debris. This will cause the airspace to collapse and allow moisture to enter Wythe (vertical layers). This can cause dampness and even mold growth. Also, debris and obstructions may build up at the Cavity’s bottom, allowing moisture upwards. This can lead to visible mold growth or dampness in the interior walls.

 

Before cavity wall insulation can go in, it is necessary to clear the cavity from all debris and rubble. Since the inception of cavity wall construction, properties have been identified as having minor and sometimes major blockages/obstructions within the airspace (cavity).

 

These obstructions can be caused, but are not limited to:
  • Before construction, the dwelling’s cavity wasn’t adequately cleared.
  • Alterations to the dwelling (e.g. All modifications to the dwelling (e.g., extensions, wall removals or wall tie replacements) are possible.
  • You can reduce the risk of cavitation by replacing your windows and conservatory structures.
  • General improvements/repairs: Installation of balanced flue heating systems/vents
  • Replace wall ties that allow debris/rubble to enter the cavity from the inside.
Sometimes, cavity wall insulation can have the same effect as installing wall ties. Even after drilling the outer layer, brick and mortar can still enter cavities. It is possible for debris and obstructions to get into cavities and allow moisture to penetrate the outer (vertical) layer. This can cause dampness and mold growth.

 

The cavity can also become clogged with debris and other obstructions. This can allow moisture to seep through the obstructions. This can lead to dampness that can cause mold growth or fungi.

 

It doesn’t matter if insulation has been installed on the cavity wall. Transmission and bridging can be achieved. Cavity wall insulation alone is not enough to stop this happening. Cavity wall insulation is not enough to prevent this from happening. This will increase the chances of cold-bridging or capillary action.

 

Below are images showing rubble and debris inside cavities walls made of masonry. These properties can result in cold bridging (or capillary action) which is the transfer and retention moisture.

 

It doesn’t really matter if the cavity wall has transmission or insulation; it can still cause problems. No matter how cavity wall insulation is installed, this problem can still occur.
  • Your property’s value will drop
  • This could lead to structural issues of critical importance
  • Reduce heat retention and increase fuel use
  • Get your walls wet from the inside.
  • Your health can be negatively affected by your choices
Clearing the airspace or cavity from obstructions and debris is crucial. Dry insulation is less effective than dry insulation and can lead to higher fuel consumption.
