FAQs

Do I need planning permission for external wall insulation?

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.

Will external wall insulation stop condensation?

Damp issues on a property are usually generated by a lot of factors such as a poor or broken guttering, condensation and lots more. The question arising here is what is the possibility of External Wall Insulation (EWI) preventing condensation? Not only is EWI a reliable way to reduce condensation-caused damp, but it’s also one of the major reasons property owners in solid wall homes consider thermally rendering or cladding their external walls.

Condensation arises as a result of warm moist internal air hitting a cold surface such as the steaming up of both windows and mirror when having a shower. What happens here is the condensation of the water vapour in the air from a gas to liquid in the process of touching the cold surface - one whose temperature is significantly reduced to reach the dew point. At the dew point, condensation is very rampant, and to tackle this issue you’ll have to heighten the wall temperature in order to convert the moisture to vapour and permit it to pass through the wall. And that’s exactly the job of an external wall insulation!

To get started you must ensure that the walls are clean and dry prior to fitting the external wall insulation. The month of May through to September when the weather tends to be dry and more stable are usually the best period to carry out the project. The external wall insulation will function just like a cosy blanket around the building. Ultimately, changing the feel and temperature of the inside of your home. As a result, the previously cold walls will no longer be cold which goes a long way to mitigate the effects of condensation. Furthermore, when an EWI is installed, the rooms of your home will automatically trap more thermal mass as the heat is saved in the walls’ fabric and released back when the temperature drops.

Is external wall insulation safe?

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.
