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 Traditional Insulation Often Fails in Non-Traditional Builds

Properties like Cornish units and concrete-framed homes act differently to standard brick-built houses. Standard insulation methods often fail to account for the unique structural makeup of these builds, which can lead to issues with moisture and thermal bridging if not handled by specialists. Our team understands the specific requirements of these structures, ensuring that any insulation installed improves your EPC rating without compromising the integrity of your property. We focus on moisture management and breathability to keep your home healthy while significantly lowering your monthly heating costs.

Our Expert Approach to PAS 2035 Compliance

When upgrading a non-traditional build, compliance with current safety and efficiency standards is vital. Global Plastering operates as a fully PAS 2030 accredited installer, adhering strictly to PAS 2035 standards throughout every project. We conduct thorough retrofit assessments to determine the most effective strategy for your specific home type, whether that involves external wall insulation to wrap the exterior or carefully planned internal wall solutions. By following these rigorous guidelines, we ensure that your property is future-proofed against rising energy costs and changing environmental regulations.

Long-Term Protection with SWIGA-Backed Guarantees

We know that renovating your home is a significant investment. That is why we provide Insurance Backed Guarantees through SWIGA for our insulation work. This provides our clients in Treharris and across the Merthyr Tydfil area with extra peace of mind, knowing that the professional standard of our installation is protected long after the project is complete. Our team combines technical expertise with reliable, high-quality materials to ensure your property remains warm, dry, and energy-efficient for years to come.

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.
