Cavity Wall Insulation Damp – How To Deal With It

Cavity wall insulation damp is a clear sign that no damp wall sealer has been applied when your home was insulated. If your home was built before the 1920s, most likely your property is not even suited for cavity wall insulation. However, there are many factors that could cause dampness, from your property structure, the environment you live in, how the insulation job was delivered and the materials used. So let’s look at how you can deal with cavity wall insulation problems. To start with, let’s understand what cavity wall insulation is used for and what it is made of. The main purpose why we started insulating our homes (in around 1935) was to cut down on heat loss. Research shows that up to 35% of the heat in our properties is lost through the walls, or more precisely air gaps in the walls. By insulating the walls we are reducing that heat loss, which means we need less gas or electricity to keep warm during the winter. Since we are using less energy we are also paying less on our gas or electricity bills. Some statistics suggest that you can expect around £90 savings per year on your electricity or gas bill with home insulation. This can be increased by having an external masonry sealer or brick sealer applied as well. There are other benefits involved as well, from soundproofing your property to keeping the temperature balanced in the summer and even reducing your carbon footprint. In terms of how your home is insulated, you have a range of materials to choose from, and some may be better than others for your property. Some of the materials used for cavity wall insulation are different variations of foam, blown mineral wool and beads and granules.

Cavity Wall Insulation And Damp – Main Cause

Cavity wall insulation and damp are not meant to go together, especially if an external wall sealer has been applied. The purpose of cavity wall insulation was to prevent the humidity and dampness that was usually caused by solid-walled dwellings. Statistically speaking, unfilled cavities are much more prone to dampness and condensation than filled ones. So, what causes dampness to appear on properties that have cavity wall insulation? Usually, there are faults with the cavity wall construction. If your property was built prior to 1920–1935, it might be unfit for cavity wall insulation. This means that you should have never had had insulation work done on your property and the professionals that carried out your construction work should have warned you about it. Other important factors to take into consideration when installing cavity wall insulation are the environment and weather conditions. Heavy rain and wind could expose your walls to moisture. Unless the property structure protects the wall from driving rain, you may not be able to use cavity wall insulation. What would happen is that the cavity will absorb the moisture inside and start creating dampness. Other factors that are important when looking to avoid cavity wall insulation and damp problems are the type of insulation material used, the masonry material and the pointing of the external masonry leaf. If you haven’t had cavity wall insulation installed, ensure to get your property professionally assessed for suitability to this type of insulation. However, if you already have the insulation installed and you are seeing damage effects, contact a professional right away.

You’re Not The Only One Facing Cavity Wall Insulation Damp Issues

Although cavity wall insulation is very popular in British homes, cavity wall insulation damp issues are very common and usually not dealt with. If you are among those homeowners who paid to insulate their property, hoping to save on utility bill costs and stay warmer in winter but ended up with condensation and cavity wall insulation damp, you are not alone. Not only are you one of the many homeowners facing these problems, but you are also able to get support. Unfortunately, some cavity wall insulation installers fail to survey your property correctly and deliver a poor installation of the cavity filling. Whether you’ve paid for the insulation in full or got a discount from the council, you should still follow up with any issues or damage that the insulation caused to your property. Some homeowners are hesitant to take action, thinking that there are no organisations that will protect their consumer needs, especially in case they paid a reduced price or even got the cavity wall insulation work done for free as part of a government project. That is not the case, because cavity wall insulation damp issues can cause serious damage. If the moisture damages the walls, it can depreciate the value of your property, affect your comfort and quality of life in your own home and even act as a hazard to your health. Today, many homeowners are frustrated with the poor practice shown by cavity wall insulation companies and feel that the industry is profit-driven and disregards the dangers that poor practice can present for their health and wellbeing. If you find yourself in this situation, seek advice from experts in cavity wall insulation claims.
