Why Choose Our Non-Traditional Build Insulation Services?

Based in Ferndale and covering South Wales and South West England, Global Plastering provides specialist thermal performance upgrades for complex property types, including Airey, Cornish units, and Wimpey no-fines concrete homes. Trust our fully insured, seasoned experts to effectively treat cold walls, drastically reduce your energy bills, and safely improve your property's EPC rating.

Why Your Non-Traditional Home Needs Professional Insulation

Non-traditional homes frequently suffer from cold walls, persistent draughts, and high energy bills due to a lack of sufficient thermal protection. Without the right insulation, these properties are prone to thermal bridging, which can lead to internal condensation and damp problems. By installing high-performance external wall insulation, we create a continuous thermal envelope around your house. This not only traps heat inside during the winter months but also helps regulate temperatures in the summer, making your living space significantly more comfortable and cheaper to run.

Our PAS 2030 Accredited Retrofit Process

We pride ourselves on our technical expertise and compliance with industry standards. As PAS 2030 accredited professionals, we follow the PAS 2035 retrofit framework for every installation in Y Gelli Gandryll / Hay-On-Wye. This structured approach begins with a comprehensive technical assessment to determine the exact requirements of your property, whether it is a detached bungalow or a semi-detached system-build. We then implement a bespoke external wall insulation system tailored to your building, finished with high-quality rendering to ensure your home looks as good as it performs.

Improving Your Property EPC Rating and Compliance

For homeowners and landlords in Powys, energy performance is more critical than ever. Improving your EPC rating is essential for meeting modern housing standards and increasing the long-term value of your property. Our specialist insulation services help bring older, non-traditional builds up to current energy efficiency benchmarks. By reducing heat loss through the walls, we provide a practical solution for decarbonisation that satisfies both current environmental goals and local regulatory requirements. We provide full documentation for our work, ensuring your property is fully compliant and future-proofed.

Peace of Mind With SWIGA-Backed Guarantees

We understand that investing in your home is a significant decision. To provide absolute peace of mind, all our insulation projects are supported by SWIGA-backed guarantees, ensuring that our work meets the highest quality and safety standards.

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!"

FAQ

Frequently Asked Questions

Answers to common questions about our specialist non-traditional build insulation and retrofit services in South Wales and South West England and across South Wales.

What is a Wimpey no-fines house and can it be insulated?

+

A Wimpey no-fines house is built using concrete that doesn't contain "fines" (small stones or sand), creating a porous structure. These homes are perfect candidates for external wall insulation. Because the walls are solid, EWI is the most effective way to stop heat loss and prevent the damp issues often associated with this build type.

Will I need planning permission to insulate my Airey or Cornish unit?

+

In many cases, external wall insulation falls under permitted development. However, because it changes the appearance of the property, it is always best to check with your local council in South Wales or the South West. If you live in a conservation area or a listed building, stricter rules apply. We can help you understand the requirements for your specific location.

How long does it take to install insulation on a non-traditional home?

+

Most domestic projects take between two to three weeks, depending on the size of the house and the weather. We manage the scaffolding, the delivery of materials, and the final clean-up, so you don't have to worry about the logistics.

Can you help with hard-to-treat properties like Airey houses?

+

Yes, Airey houses are a core part of our business. These homes have a specific concrete pier and panel construction that requires a specialist approach to fixing insulation. We use industry-approved methods to ensure the structural integrity of your home is maintained while we upgrade its thermal performance.
