Why use External Insulation in Wales?
External Insulation Wales with Be constructive Ltd ..
External insulation is a modern fantastic way to improve the efficiency of solid brick properties without a cavity. For many years, this type of wall – generally built prior to 1945, was only able to be insulated internally. This is very disruptive and reduces the size of the rooms, so there are very few homes with this type of insulation.
In the last few years, external insulation has come across from Europe, where walls have been insulated using this method for around 40 years. It is a great way to insulate your property in Wales because:
- It will bring your home up to the same energy efficiency as a new build construction.
- It gives you a chance to refresh the look of the property and replace any damaged or blown render.
- It will help with penetrating and condensation based damp in the property.
- It will make the house feel much more comfortable and warm. You will find the temperature drops much more slowly when you turn your heating off.
Be constructive ltd has been carrying out External wall insulation work in Wales for many years, and use only the best products with the EWI Pro system Sto and many others to give you a bright and warm home for many years to come. Our insulation is guaranteed for 25 years, and can be expected to last at least 50 years according to the BBA. We are a PAS 2030 accredited installer too, which means we deal with building control certification for you and are quality assured via our accreditation body.
External insulation is made up of the following parts:
- Insulation boards, typically around 100mm thick and made of EPS.
- Adhesive and mechanical fixings to hold the insulation on the wall
- A base coat with fibreglass mesh to strengthen the system
- A thin coat render made of silicon or acrylic.
As part of the works we will extend any pipes of fixings that may be present on the wall as part of the job, so you only need one company – Be constructive Wales – to carry out the whole job.

We often see render that has cracked, blown or is just poorly applied. The solution is usually to strip the wall back to brick and start again to provide an extended warranty on the work, but it may be possible to carry out corrective works that avoid having to go to such drastic steps. Applying render is a skilled job, and you should ensure you use an accredited installer like BE constructive ltd for this, or you could end up with a pig’s ear of a job.
We recommend modern render systems like EWI Pro or K-Rend rather than old sand cement render. The cost will be higher, but you will have a much longer lasting and durable system than with the sand cement renders.
Cavity Wall insulation and extraction
In Wales we see a lot of incorrectly installed cavity insulation – in some cases in properties that never should have been insulated in the first place. If you have damp as a result of poorly installed insulation, just give us a call and we can assess your options, and if necessary quote to carry out cavity extraction.
External insulation Wales remedials
As well as all the problems that come with poorly applied render, EWI can also create its own problems if poorly installed. Common areas of concern are poorly sealed and finished verges, incorrectly fitted mechanical fixings creating shadows on the top coat, and cold bridges from incorrectly fitted boards.
Whatever your problem, give us a call and we can discuss your options and the next steps.
External insulation is big business in Wales, and in this blog we are going to tell you why it is so effective in this part of the country, and why you should get external insulation for your property.
Why is EWI Effective against Damp?
In a wet and windy place like Wales, your external walls face a daily battle against the elements to keep your home dry and warm. Driving rain attacks your walls and can make its way through brickwork and into your internal plaster. This is really bad news because you can end up with mould and damp throughout your home.
For many years in exposed parts of the UK like Wales, thick renders with pebbledash have been used to help create a coating that stops moisture from penetrating the brickwork. This works reasonably well at stopping penetrating damp, but it doesn’t really deal with condensation, where moisture in the air condenses on the exposed walls.
EWI on the other hand, deals with both penetrating damp and condensation based damp in one go. It actually warms up those external walls and prevents condensation from forming, whilst also preventing damp from penetrating through the brickwork.
EWI for Cavity Wall Properties?
Cavity wall properties are normally insulated by pumping insulation into the gap between the bricks. In sheltered areas where driving rain is less of a problem, this is a good way to insulate the property. In Wales however, many homes are subject to more intense weather than say, the East of England. It means that properties in these exposed areas, if cavity insulated, can cause damp as the insulation bridges the gap between the two layers of brick and creates a pathway for moisture to get at the internal walls. In this case, EWI may be a good alternative, as it protects against penetrating damp and will avoid the issues that can arise with cavity insulation. It will also help make the walls even more well insualted than cavity insulation, as the insulation can be much thicker than in the standard cavity.
So for an area like Wales, EWI is a good option to prevent and negate damp.
