Specialist Insulation for Non-Traditional Homes in Rhondda

Global Plastering provides expert insulation solutions for non-traditional and system-built homes across Rhondda and the surrounding 35-mile radius. Many properties in the Rhondda Cynon Taf area, such as Airey houses, Cornish units, and Wimpey no-fines constructions, were built using methods that often result in poor thermal performance. If you are struggling with a cold house, high energy bills, or persistent condensation, our team offers the specialised knowledge required to transform these unique properties into warm, energy-efficient homes.

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 Do Non-Traditional Builds Need Thermal Upgrades?

Properties built after the war using concrete panels, steel frames, or no-fines concrete often lack the thermal mass and insulation found in modern homes. In Rhondda, these buildings are prone to thermal bridging, where heat escapes rapidly through the structure. By installing high-performance external wall insulation, we create a continuous thermal envelope around your property. This approach not only stops heat loss and draughts but also prevents moisture build-up and mould growth, which are common issues in these specific construction types.

Our Approach to PAS 2035 Retrofit Standards

As fully PAS 2030 accredited specialists, we take a whole-house approach to every project. We understand that non-traditional builds require more than just a quick fix; they need a calculated strategy that respects the original structure while bringing it up to modern EPC standards. Our process starts with a thorough retrofit assessment to identify the exact needs of your building. We then install bespoke insulation systems that improve your energy efficiency while ensuring the building remains breathable and structurally sound.

Reliable Solutions for Landlords and Homeowners

Whether you are a private homeowner looking to lower your heating costs or a landlord needing to meet MEES compliance, our services are designed to protect your investment. Improving the EPC rating of a system-built home is one of the most effective ways to increase property value and tenant comfort. Because we are CHAS accredited and offer SWIGA insurance-backed guarantees, you can rest assured that your project is handled by professionals who prioritise quality, safety, and long-term performance.

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!"

M. Lewis (Cardiff)

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.
