FAQs

Are there grants available for external wall insulation?

External wall insulation works to keep your home cosy and comfy while also helping to cut the energy bills. However with the great benefits also comes great costs, so it’s actually a logical decision to know whether there are grants out there which you’re eligible for to help you handle the cost of the external wall insulation.

There are grants available for external wall insulation, but rarely will you find one that covers the full installation cost. With the help of the government’s Energy Company Obligation (ECO) scheme, a couple of energy companies assist in making your home more energy efficient by offering grants or free insulation. In certain cases whereby you receive particular state benefits, you may as well qualify for a higher grant that’ll cover more of the insulation cost.

However, if your energy supplier doesn’t offer any grant, you need not worry as you can save as much on energy bill after installation. Here’s what insulation can help you save per year on energy bills:

• Floor insulation can help you save within a range of £30 to £75 each year.

• Cavity wall insulation can help you save about £85 to £280 a year.

• Loft Insulation (270mm) can help you save about £135 to £250 a year.

Generally, the amount you’ll be able to save on your energy bills depends mainly on the type and size of your property, as well as how energy efficient it already is without the insulation. In the long run, your external wall insulation will more than give you back your investment on the valuable project through your savings on energy bills. In other words, whether or not you’re eligible for a grant should never stop you from installing an external wall insulation.

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.

How good is external wall insulation?

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. Installing an external wall insulation comes with a variety of benefits, let’s have a look!

• Thermal Performance Improvement

With EWI, the thermal inertia of the walls are greatly enhanced while also restricting the loss of heat. Ultimately, this lowers heating costs, enhances the comfort of indoor thermal and also reduces CO2 pollution.

• 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!
