A wall does numerous things, just one of which is to hold the roofing system up. Considering that the 1970s the wall surface's role in maintaining the warmth in has actually become significantly crucial.

Outside wall insulation includes fixing a layer of insulation product to the wall surface, after that covering it with a unique sort of render (plasterwork) or cladding. The surface can be smooth, textured, painted, tiled, panelled, pebble-dashed, or completed with brick slides.

 

Is External Wall Surface Insulation Worth doing?

There are a variety of concerns to be attended to before setting up outside wall surface insulation, however the benefits are numerous, consisting of:

  • Lowering warm loss and also power bills
  • Minimizing drafts and increasing the sense of convenience
  • It does not disrupt the house while being mounted
  • It does not lower interior flooring location
  • It enables walls to add to thermal mass (the 'tea cosy' effect).
  • It improves weatherproofing and sound resistance.
  • It enhances the life of the wall.
  • It decreases condensation on inner walls.

 

Is Planning Consent Needed for External Wall Insulation?

Whatever else outside wall insulation does, it will certainly change the external look of your home. In most cases that will mean getting preparation authorization before embarking on the job, so do check with your local authority from the outset. For homes in Conservation Areas and for noted buildings it is fairly possible that consent will certainly not loom.

Under Building Regulations, if 25 percent or more of a wall is to be protected externally, it is commonly required to bring the whole wall approximately present requirements-- which makes feeling in that, if you're going to go to the efforts and also cost of insulating on the surface, then you may as well do it well. The thermal efficiency of the shielded wall should have a U worth of no more than 0.30.

 

How much will it set you back?

External wall insulation is expensive yet effective. Adding it as part of a larger task will certainly lower the cost, plus it does not need to be done to the entire residence; an eye-catching front altitude might be more suitable to inner insulation, while less eye-catching side and also back elevations can be protected on the surface. However even with the greater expense, the advantages external insulation provides over internal mean that it is difficult to disregard.

  • External wall surface insulation: around ₤ 10,000.
  • Interior wall surface insulation: around ₤ 8,200.

FAQs

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.

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.

How to fit external insulation?

With the title of this blog, do not be deceived into thinking the purpose is to encourage you to install an external insulation by yourself. Even as a competent DIYer, it’s not advisable to buy a couple of materials and start slapping it into the wall hoping for the best outcome. External insulation is by no means a DIY job and without the proper training and experience, it can easily turn out disastrous resulting in loss of time, effort and money in such a valuable project. This blog, however, will give you a great insight on how the installation process works and help maximize knowledge ensuring you do not spend more than necessary.

External Insulation Installation

lRender Test

• This is done to ensure the existing render is good enough for insulation support.

• If positive, the insulation can be applied directly onto it.

• If negative, ensure removal of the old render before fitting the insulation.

lPipework Adjustment & Removal

• Remove all pipework prior to insulation fitting

• Install temporary downpipes to ensure water is not wasted and everything continue to function normally during the insulation fitting process.

lWindow Protection

• Protect the window with a protective layer or film.

lStarter Track Fitting

• Determine level you want the insulation to start (height).

• Fit the aluminium start track or carrier tray at the identified level.

lInsulation Boards Fitting

• Apply a layer of adhesive to the board and glue them to the wall in a staggered pattern.

• Cut to fit round all obstructions and windows.

• File off the edge of the board where necessary using a rasp upon successful fitting of the boards

lMechanical Fixing Inclusion

• Hammer around 10 fixings per square metre into the board.

• This is to secure the insulation boards.

lBeading Fitting

• Add corner beads and stop beads to ensure the insulation is secure and to prevent it from making contact with other materials.

lReinforcing Mesh & Render Addition

• Apply two layers of strengthening properties and between the two layers of render, include a fibre glass mesh.

lPrimer Application

• Paint on the primer

lFinal Render Application

• Choose your most preferred texture and colour as this will be the last coating of the installation process.

lPipework Re-installation

• Re-install all detached pipework at the start of the installation process.
