Why Choose Our External Wall Insulation Services Across South Wales?

How EWI Transforms Your Property Efficiency

External wall insulation works by applying a high-performance thermal layer to the outside of your building, which is then protected by a durable, weather-resistant finish. This process effectively wraps your home, preventing heat from escaping through the walls and addressing the root cause of thermal bridging. By tackling heat loss at the source, our EWI systems drastically improve your property’s EPC rating and create a much more comfortable living environment all year round.

Professional Solutions for All Property Types

We have extensive experience working with a wide range of building styles found in Nantyglo. From the unique needs of Victorian terraces and period properties to the structural requirements of Wimpey no-fines houses and other non-traditional constructions, we offer bespoke solutions. Our team ensures that all installations are handled with care, preserving the character of your home while delivering the modern energy efficiency required for contemporary living.

Quality Finishes with Silicone Render and Brick-Slip Systems

Beyond the thermal benefits, our EWI services offer a fantastic opportunity to refresh the exterior appearance of your property. We offer a variety of high-quality finishes, including modern silicone render in various colours and textured brick-slip systems that mimic traditional masonry. These finishes are not only aesthetically pleasing but also act as a protective shield for your building fabric against the challenging Welsh weather.

What Our Clients Say About Global Plastering

"Excellent work the team removing our old 1970's cladding and replacing it with insulation and a rendered finish. The job went smooth from start to finish with all old materials removed from site. We are very pleased with the end result and would thoroughly recommend Global Plastering."

A. Jenkins (Ferndale)

"Dilwyn and his team were brilliant and made a lovely job of our EWI. They were very friendly, hard-working, and left no mess at the end of each day. Our house looks great and we can definitely feel the benefits of the insulation already. I'm very glad we chose EWI especially with energy costs as they are now."

G. Toogood (Bristol)

"Charlotte and the team were professional, reliable, and excellent at communicating throughout. They did a fantastic job of skimming and rendering the back of our house during our renovation. Superb quality of work and highly recommended!"

Expert Advice

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited external wall insulation, solid wall solutions, and energy efficiency services in South Wales and South West England and across South Wales.

Will EWI make my home look different?

+

Yes, but in a good way. You can choose from a wide range of silicone renders or even brick-slip finishes. If you live in a Victorian street, we can often match the aesthetic of the surrounding area while vastly improving the thermal performance.

How long does the installation take?

+

For a standard semi-detached house, the work usually takes between two and three weeks, depending on the weather. Because all the work happens outside, there is very little disruption to your daily life.

Do I need planning permission for external insulation?

+

In most cases, EWI falls under permitted development. However, if your home is a listed building or in a conservation area, you might need permission. We can advise you on the specific rules for your location in South Wales.

Can I get a grant for external wall insulation?

+

There are often government schemes available to help with the costs of energy efficiency improvements, especially for those in fuel poverty or living in certain postcodes. We can help you find out if there is any current funding available for your project.

Is EWI better than internal wall insulation?

+

EWI is generally preferred because it doesn't take up any floor space inside your rooms and it does a better job of covering thermal bridges (areas where heat escapes through the structure). It also protects the exterior fabric of your building from the elements.
