Cavity wall insulation can go wrong if installed in a property that is inappropriate for it.

We are always hearing about cavity wall insulation problems, but do we know the actual purpose of a cavity wall? And what problems often occur with them? This article will give you an insight into what you need to know about cavity wall insulation problems.

A cavity wall consists of two separate walls that have been built within a close distance from each other with a space in between them. These walls can be constructed in brick or concrete, or from other materials. The space in between them allows the cavity wall to be efficient with insulation than a single-layered wall would be. The moisture that’s absorbed into the brickwork of the outer wall will drain through the space and out through the base of the wall. In order to be at its best, the space within the cavity wall must be sealed off where doors or windows are built into the wall.

You should ideally check that your cavity is clean before filling it with insulation. A reputable insulation company will do this for you as a matter of routine and give you an honest answer based on their findings. This is a quick and easy process of drilling some 15mm holes into the wall, placing a small camera into them and then seeing what the cavity is like.
With this in mind, it’s very common that cavity wall insulations often occur problems. This may include cold patches on external walls and internal damp problems, the growth of mould, damaged cavity wall insulation, and wet cavity insulation. If you’re experiencing any of these problems, you’re probably wonder why it’s happening.

Cold spots on external walls may be caused by some areas of the cavity wall that haven’t been correctly insulated. Internal damp problems may be caused by warm air condensing onto cold spots which haven’t been insulated properly. Mould growth could be caused by the damp reoccurring into the cavity wall. Damaged cavity wall insulation could be caused by flooding or other factors. If this is the case, it may be best to contact a cavity wall insulation company or service and they will be able to fix any problems you may have with your cavity wall insulation.
