Cavity Wall Insulation usually comes with various advantages and is a solution to heating loss. However, this solution also has many disadvantages which might make its potential users think twice before getting it installed and a compensation claim is often needed.
- While many installing companies would boast about how installing cavity wall installation is a solution convenient and light on your pocket, there is a bunch of critics suggesting otherwise. The cost of the insulation depends on the type of material which is used. E.g. if it is recycled paper is may be cheaper than the glass insulation material. Also, one cost which is not at all included in the budget is the cost of the experts who would install the cavity wall insulation. It is not a typical DIY project and requires a team of trained people who up the budget drastically. The special equipment to drill the holes is also an additional cost
- If they experts hired are not good with their work, a very common problem with the cavity wall insulations is that these walls are often left with insufficient insulation with too much empty space in the walls. Though it may seem like a minor fault by the workers, it costs the homeowner that entire he has invested in the walls. This little fault is enough to finish all the advantage of the insulations and make it completely useless. As a result the rain water will be in after some time and the heat will also escape the walls quickly, bringing no change to the heating bills
- One of the major drawbacks is that cavity wall insulations can’t be installed in every household. This is because many houses are old constructions which have more solid walls and it is impossible to inject the insulation in them
- As mentioned previously, if there is a slightest problem in the installation of the cavity wall insulation, it doesn’t work properly. In such cases the most evident and most common problem is the dampness and the molds it creates in the house. The dampness surely creates a very foul smell around the house but apart from that, there are many health hazards linked to it. Firstly, it leads to the birth of bacteria as moisture is the prime breeding ground for it. Bacteria can be on anything from the furniture to the walls and floors and can further lead to many diseases.
- The dampness that the walls might create will definitely lead to an outbreak of the unwanted pests. In case the insulation goes wrong, be ready to welcome all kinds of rats and cockroaches who love to reside on damp areas
- Lastly, the dampness of the walls is likely to result in dust mites. The dust mites can result into respiratory problems and can easily become the cause of issues like eye irritations and flu. Plus, is the worst for an asthmatic person as it can lead to constant irritation in the breathing passage
All these are the disadvantages of the cavity wall insulation or in case they go wrong which has been a very popular case in Europe. However, the good news is that since the government has enforced to get the cavity wall insulations, it is the government which is liable to pay for the damages. There have been quite some people who have filed a case against poorly installed and or low quality wall under the Contracts (right of third party) Acts 1999 and as well as Sale of Goods Act 1979.
The government compensation greatly dulls many of the cavity wall insulation disadvantages and makes its advantages overshadow its drawbacks once again.
