Cavity Wall Insulation Removal by Experts. If your home is effected by Damp or Mold and has cavity wall insulation then you may need it extracted. Remedial work should be carried out by Experts with the necessary expertise in this very specialist area of building repairs.
Known Problems with Cavity Wall Insulation
Cavity wall insulation was marketed in the early days as a means to saving on heating bills. As a result of this a massive campaign was released by the UK government promoting the benefits of saving energy. Consequently many new specialist companies sprang up all over the place, specifically to sell and install cavity wall insulation. Some of these companies were good, but unfortunately some were not. For us to understand cavity wall insulation problems then we need to initially look at why buildings are built with a cavity in the first place. Basically a cavity between the two walls was thought to act as a barrier against damp. The outer wall would absorb weather and the air in between would prevent any damp moving into the building�s interior. This works fine until you fill that gap with a material that acts as a bridge between the cavity. In some cases, and in certain areas this has become a serious problem, specially on gable ends that face continuous weather fronts. It is important to understand that the cavity had one job, and that was to keep rain out. It was not until later that newer materials were used on the inner wall to help control temperature.
Since the 80�s it has become a regulation that new homes will be built with insulation pre-installed to help further reduce energy costs. Most of the time this works fairly well as it still allows air to flow between the two walls. The insulation used is normally fibre board which is attached to the inner wall. These fibre boards actually help to prevent damp problems as they are designed to allow water to track down and never touch the inner wall.
Cavity Wall Insulation Problems with Mold and Damp in Older Pre 1980 buildings
Damp and mold Patch in need of cavity wall insulation extraction Damp and Mold patch. Most damp problems were confined to three major things.
Wall ties that had mortar attached and therefore acted as a bridge between the walls.
Cavities that have become filled with low levels of mortar droppings or building debris.
In coastal areas sand which has blown in through faulty air vents or roof damage.
All three of these problems could cause damp patches. These problems were easy to put right, simply requiring a few bricks to be removed and a simple clean up operation of the effected area of the cavity void. Sometimes a wall tie might have been placed at a slightly angled trajectory, and this too could cause some damp or mould patches to appear. By replacing the effected wall ties the fault is still a reasonably simple problem to remedy.
Cavity Wall Insulation Problems in Post 1980�s Buildings
Unfortunately there have been many issues where Cavity Wall Insulation has been miss-sold or not installed correctly. This has lead to wide-scale issues of damp, condensation and Mold and other related issues with the construction of properties. Our support Staff will assist you all the way stages of the process.
