Why Choose Our External Wall Insulation Services Across South Wales?

Why Solid Wall Insulation Is Essential for Your Property

Many traditional properties throughout the Rhondda Cynon Taf area were built without modern insulation standards, meaning heat escapes directly through the masonry. Our EWI systems act as a thermal blanket, eliminating cold spots and preventing thermal bridging that often leads to mould growth. By upgrading your insulation, you will notice a significant improvement in your home temperature and a reduction in your monthly energy spending. This process is particularly effective for Victorian terraces, semi-detached homes, and non-traditional builds, providing a robust, long-term solution to rising energy costs.

How Our PAS Accredited Installation Process Works

We take a precise, evidence-based approach to every project in Abercynon to ensure full compliance with PAS 2035 retrofit standards. Our process begins with a detailed survey to assess the thermal performance of your walls and identify any areas requiring specific attention. We then install high-grade insulation boards, followed by a durable, weather-resistant render finish that significantly enhances your home exterior. Our team manages every stage of the installation with minimal disruption, ensuring your project meets all building regulations and safety standards.

Do You Need to Improve Your Home EPC Rating?

For landlords and homeowners alike, energy performance certificates are becoming increasingly critical for property value and rental compliance. Improving your EPC rating through external wall insulation is one of the most effective ways to meet MEES regulations and ensure your property remains attractive in the local market. Our work not only lowers the carbon footprint of your building but also adds a clean, aesthetic facelift that modernises the look of your home. Whether you are aiming for a warmer living environment or preparing a property for the rental market, our solutions are tailored to your specific needs.

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.
