With the numerous benefits that comes with the installation of an external wall insulation in a building, it’s also important to find out whether it’s also safe before proceeding to fit one in your home. Firstly, to ensure that external wall insulation systems are safe, they must be BBA approved, which means they’ve been subjected to a thorough testing by the British Board of Agrement and therefore, suitable for use in UK homes.
Given the fact that cladding materials have recently generated a lot of debate and negative press about how reliable some particular materials are, questions are being asked of the safety and reliability of external wall insulation. However we must clarify that, although external wall insulation can be classified under cladding, it is very different to rainscreen cladding - which caused the Grenfell fire tragedy.
External wall insulation is completely safe. However, when it comes to fire, the safety of your system depends largely on the insulation type in question. The safest type of insulation you can have installed is the Rockwool insulation boards which are rated as Euroclass A1 non-combustible. The board is specially designed in such a way that it contains fire - preventing it from reaching the other areas of the building. They also do not produce harmful emission or smoke when impacted by fire.
Meanwhile, the Wood Fibre, is also a great insulation which is known to char and not burn. Contrary to many beliefs, it actually burns slowly creating this charring effect which produces an oxygen barrier that helps reduce the spread of fire.
To make your system safer, you can also make use of Fibreglass Mesh for reinforcement. It helps to improve the strength of the tensile which promotes the security of the boards attached to the wall.
If you want to install an external wall, it is only wise to consider whether or not a planning permission is required in order to avoid a hefty fine. In a great kudos to the government and a welcome relief to home and property owners, the installation of external wall insulation is seen as an “improvement to the house and not an “extension or an “enlargement. Ultimately, this implies that external wall insulation fitting is to be done under permitted development and a planning application may not be required. However, like many other regulations, there are also exceptions to this rule and the main one is if the activity changes the appearance of your property. Properties such as a listed building having tighter regulations may pose some issues. As a result, we’d advise you to consult your local authority to ensure that there’s no fast rule to this topic before commencement of the external wall insulation project.
At the moment, according to the Government Building Regulations, the surface of the entire wall is to be improved to existing standards if the area to be insulated exceeds 25 percent of the wall. In normal situations this is usually the typical case, however to prevent avoidable fines and other possible punishments, it is always best to reach to your local authority and check out the rules guiding external wall insulation in your constituency. Furthermore, since external wall insulation is not a task that’s recommended to be done by yourself, you can also ask the professional external wall insulation fitting company for the applying rules before proceeding. As a good professional, the company should have a better knowledge of the rules and regulation guiding its activities.
External Wall Insulation (EWI) is the act of insulating a home by fitting insulation to the exterior parts of the building which in turn improves thermal performance, cuts energy consumption ( savings on energy bill) and also adds to the home’s visual appeal. The systems are built in multiple layers, with the insulation board offering a plethora of options with each being suitable to varying projects and their needs.

• Eliminates Noise Pollution
When the noise levels are high, it can have a bad impact on our overall well being. A great way to reduce the disturbances from the outside like traffic noise is by fitting an External Wall Installation system.
• More Comfortable Living Space
Do you know the damp in homes can contribute to respiratory problems? A properly insulated home will greatly limit the impact of condensation by combating the damp issues. As a result, you can always expect your house to be cosy and comfy irrespective of the season. A cooler summer and warmer spring is guaranteed with EWI.
• Enhances The Property’s Visual Appeal
Looking for an excuse to rejuvenate your home’s aesthetic appeal? Well, you can as well try out adding an EWI system. There are a plethora of unique colours and styles you can pick from to beautify your home effortlessly.
• Adds Value To Property
An insulated home will generally cost more than an uninsulated one at the time of resale. Potential home buyers are more interested in the acquisition of a home with an EWI system due to its various benefits - and a higher demand can only imply a higher price!
