Having Trouble with Cavity wall insulation problems? Usually with steel or wooden framed properties, there have been many occasions in which the insulation has been fitted into houses which is structurally unsuitable. Cavity wall insulation problems can also occur in brick or block work constructed properties near the coast as they are subject to wind-driven rain.
Leading to damage, reduced thermal performances and wetting of the cavity insulation, rainwater can penetrate the outer leaf of masonry under severe weather conditions. Resulting in areas of dampness, moisture is able to transfer from the outer to the inner leaves of the wall as there can be an increased risk of rain penetration if a cavity is filled with insulation.
It’s worth checking whether your home is at risk, even though cavity wall insulation causing damp can be rare. If there is a combination of these things, damp may occur in properties if:
- Your home is exposed to severe rain
- The external walls are poorly built
- Your home is located in an unsheltered position
There can be gaps where the insulation hasn’t reached if it has been poorly installed. It may be recommended that it should be removed as it can cause damp.
It’s possible that urea-formaldehyde may have been injected into your cavity wall if you had it installed a long time ago. Through a combination of gas released from the foam and damp, it can become harmful to your health and over a number of years it will degrade.
What are the signs of Cavity wall insulation problems?
Showing signs that it is defective over time, the installation can cause problems. Some problems with cavity wall insulation which you may notice include:
- Damp problems, caused by warm air condensing onto cold spots that haven’t been insulated correctly
- Cold spots, possibly caused by areas of the wall that haven’t been insulated correctly
- Damaged cavity wall insulation, due to flooding
- Mould growth, due to the damp
- Wet insulation, due to defective mortar and water penetration
Leading to damp, the cavity wall insulation can become wet and is likely to dry out when a property has been flooded. The high volume of water used to extinguish the flames in the event of a fire can also water-log the cavity wall insulation.
It is possible to remove the insulation, regardless of whether you have a mineral fibre, expanded polystyrene or urea-formaldehyde insulation. This is usually done by drilling back through the holes which were used for the original installation. A high-pressure vacuum machine is then used to suck the insulation out of the cavity.
