Specialist insulation for non-traditional homes in South Wales

Living in a non-traditional build, such as an Airey house, a Cornish unit, or a Wimpey no-fines property, often presents unique thermal challenges. Many of these post-war structures were built using concrete, steel frames, or timber without the modern insulation standards we rely on today. Based in Ferndale, Global Energy Insulation provides professional, PAS 2030 accredited thermal upgrades designed specifically for non-standard construction across South Wales and the South West. We help homeowners and landlords transform cold, damp-prone houses into warm, energy-efficient homes that are comfortable year-round.

Why Choose Our Non-Traditional Build Insulation Services?

Identifying the challenges of non-standard construction

Properties built using non-traditional methods often suffer from severe heat loss and thermal bridging, where heat escapes rapidly through gaps in the building fabric. This lack of insulation frequently leads to condensation, black mould, and soaring energy bills. Whether you live in a steel-frame structure or a concrete-walled dwelling, our team understands the structural nuances required to upgrade these specific property types. By assessing your home’s build quality, we can recommend the right balance of External Wall Insulation or Internal Wall Insulation to eliminate cold spots and protect the long-term structural integrity of your building.

How our PAS 2035 retrofit process works

We follow the rigorous PAS 2035 whole-house retrofit standards to ensure every project meets current UK building regulations. Our process begins with a detailed assessment of your property’s thermal needs and structural type. We then design a bespoke insulation solution that integrates seamlessly with your home's exterior or interior. Our installation team works with precision to prevent moisture buildup, ensuring your home remains breathable and dry. Once the installation is complete, you receive the peace of mind that comes with a SWIGA-backed insurance guarantee, ensuring your investment is protected for years to come.

The benefits of upgrading your property energy efficiency

Investing in professional insulation does more than just lower your monthly energy bills. A well-insulated non-traditional build will see an immediate improvement in its EPC rating, which is critical for landlords looking to meet MEES compliance standards. Beyond energy savings, our solutions address the root cause of damp and condensation, creating a healthier living environment for you and your family. With our sister company, Global Plastering, we provide a complete end-to-end service, ensuring that once your insulation is installed, your walls receive a high-quality aesthetic finish, from modern silicone rendering to traditional plastering.

Non-Traditional Build Insulation FAQs

Frequently Asked Questions

Expert answers to common questions about PAS 2035 compliant insulation, eliminating heat loss, and upgrading the thermal efficiency of Wimpey No-Fines, Cornish units, and steel-frame homes in South Wales and South West England and across South Wales.

Can you insulate a Wimpey no-fines house?

+

Yes. Wimpey no-fines houses are ideal candidates for External Wall Insulation. Because they lack a traditional cavity, EWI is the best way to add thermal mass to the building. This stops the "fridge effect" where the concrete walls hold the cold and radiate it into your living rooms.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under "Permitted Development." However, if the finish changes the appearance of the house significantly or if you are in a conservation area, you might need approval. We can guide you through this process and help with the necessary paperwork.

What is a SWIGA guarantee and why does it matter?

+

The Solid Wall Insulation Guarantee Agency (SWIGA) provides a 25-year insurance-backed guarantee on EWI installations. This means that even if a contractor ceases trading, your investment is protected. It is a vital trust signal that many mortgage lenders look for on non-traditional properties.
