Professional External Wall Insulation for Aberhonddu and Brecon Homes

If you are struggling with a cold house or high energy bills in Aberhonddu or Brecon, our team at Global Plastering offers the professional solution you need. External Wall Insulation, or EWI, is the most effective way to improve the thermal performance of solid-wall properties common across Powys. By wrapping your home in a high-performance insulation layer, we significantly reduce heat loss, eliminate thermal bridging, and stop draughts at the source. Whether you own a traditional Victorian terrace or a non-traditional build like a Wimpey no-fines house, our systems are designed to transform your property into a modern, energy-efficient living space.

Why Choose Our External Wall Insulation Services Across South Wales?

How our EWI installation process works in Powys

Our process begins with a comprehensive technical survey to assess your property's specific needs and compliance requirements under PAS 2035 standards. Once the design is finalised, our PAS 2030 accredited team prepares the exterior surfaces before fixing the insulation boards securely to the building fabric. We then apply a reinforcement layer and a high-quality, breathable finish, such as silicone or monocouche render, which protects against the elements while allowing the building to breathe. This structured approach ensures a long-lasting, weather-resistant, and aesthetically pleasing result that breathes new life into tired exterior facades.

Why choose EWI for your solid wall property?

The primary benefit of external wall insulation is a drastic improvement in your home's thermal comfort. By creating a continuous barrier, EWI helps retain warmth in the winter and keep your home cool during the summer, directly impacting your energy consumption. Furthermore, this process is essential for anyone looking to improve their property's EPC rating, which is increasingly important for both homeowners and landlords adhering to MEES regulations. Beyond the functional efficiency, our variety of modern render finishes provides an instant, durable, and attractive aesthetic upgrade for your home.

Expertise in complex property types and local regulations

Navigating the complexities of building regulations can be daunting, but our team manages every step of the process with full PAS 2030 and PAS 2035 compliance. We have extensive experience working with a wide range of building types found throughout Aberhonddu, Brecon, and the wider Powys area, including concrete constructions, Cornish units, and period homes. We understand the specific requirements for different wall constructions and handle the technical details, such as thermal bridging solutions, with absolute precision. All our installations are backed by a SWIGA insurance-backed guarantee, providing long-term peace of mind for your investment.

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.
