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.
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.
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.
