Insulation Installer FAQs

is cavity wall insulation a good idea?

Cavity wall insulation is basically the process of installing an insulating material between the two layers of brick making up a cavity wall, either as a retrofit measure or at the time of building. Obviously this is not a choice if you have solid wall, but for those who do possess a cavity wall, it represents an opportunity you may not want to let slide as it is a worthwhile and affordable wall insulation option. Clearly, cavity wall insulation will make your home or property feel warmer, but it also does come with a range of other benefits which is why we’d recommend installing it. In this post, we’re going to look at a number of reasons why having a cavity wall insulation done is a good idea.

  • It’s one of the cheapest energy saving measures that’s available. Not only is cavity wall insulation really effective, but it can also deliver great saving. In other words, it possesses a bigger payback compared to other options. When compared to other types of insulation, you can’t install cavity walls insulation by yourself, however it’s not so expensive to have it installed. The cost of the insulation will be determined by a number of factors such as your location, the company hired and more.
  • It reduces your energy bills. Cavity wall insulation can save you about £100 to £200 on a yearly basis on heating bills. In other words, this is usually able to pay for itself in as little as two years.
  • It reduces your carbon carbon footprint. If your home is heated with gas or electricity like several other homes, producing that energy involves burning fossil fuels which is known to be hazardous for the environment. If the heat generated is now allowed to escape through the walls, that means you’d have to use more to keep up your required temperature. Installation of cavity wall insulation in homes will enable a more efficient usage of the energy which will ultimately cut UK’s carbon usage.
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 much does external solid wall insulation cost?

Before the commencement of any project, it’s always best to get an estimation of the cost. However, determining the cost of an external solid wall insulation is not the easiest of tasks as it relies on varying components such as the insulation materials to be used, labour cost and installation as well as the type of decorative finish to be incorporated. And depending on your choice of insulation material, some may need some adhesives while others may require some fixings which also contributes to the differences in price. As a result, the determination of the material cost alone can be tricky and even more so when various materials cover varying areas.

With that in mind, the cost of external solid wall insulation generally ranges between £80 to £100 per square metre2. As a result, a small flat can cost from £6000 to £9000 whereas a large detached house can have a price ranging between £21000 to £23000. To earn back your investment in terms of energy bill savings can take a couple of years, but it’s surely worth the try as there are several other benefits associated with installing an external solid wall insulation system. What’s more? Another huge factor that can influence the cost of your system is also the amount of work that’s required, how easy it is to be accessed by the installers and lots more

If you’re looking to cut down on the cost of your external solid wall insulation, then the best time for an installation might just be when you’re having another decorating or building project done such as fitting a new roof, window painting, installation of solar PV panels and more. This way, you’ll be able to spread the cost and have a greater value for each penny expended.

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.

Does cavity wall insulation lead to damp problems?

Insulating a cavity wall should not affect the damp proofing of the wall. All insulation approved for use in cavity walls has been tested to ensure that it does not allow damp to pass through the wall. Some walls which receive a lot of wind driven rain are unsuitable for cavity wall insulation.

How to get free external wall insulation?

This is a very great opportunity to not only get free external wall insulation, but also cut down your energy bills depending on the type of property you live in. Generally, to enjoy free external wall insulation you must at least be part of the group receiving one of the benefits listed below and also depends on the amount of money you earn. The benefits include:

• Income based jobseeker’s allowance (JSA)

• Income support

• Income-related employment and support allowance (ESA)

• Tax credits

• Pension credit guarantee credit.

• Universal credit.

There are also other important factors that determines if you can have a free insulation fitted on your property. These includes the place you reside, the carbon level of your home and according to some suppliers, the level of beneficial impact the insulation will have on your home. In order to have a free external wall insulation installed, you must either be the owner of your home or at least obtain the go ahead from your landlord before any external wall insulation activity can be made.

Good news is, if you fit the aforementioned criteria and you’ve already installed an external wall insulation, you just may be entitled to receive a refund for the good job done. However, to really find out if you’re eligible, we’d recommend you get in touch with your supplier directly. Also, the Energy Saving Trust (EST) can direct you to some organizations who can assist you in the determination of your eligibility.

As a home and property owner living in England, you can also check out the Each Home Counts Advice Website which is committed to giving impartial energy efficiency advice.

At the end of the day, if it turns out you happen to be ineligible for a free external wall insulation, you can still go ahead to contact a professional installer for a help at a competitive price to enjoy the several benefits that comes with home insulation.

Here, you’ll discover the cost of insulating your lofts so you that you can set a budget and start to plan.

 

The cost of insulating a loft is actually affordable for several individuals, however, this depends on a wide range of factors such as the size of the house as well as the type of insulation being installed. One significant factor is the insulating material that you choose to install. If done properly, you’d be able to prevent heat from escaping through the roof of the house which helps improve energy efficiency and ultimately, save you some money on heating bills.

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.
