Why Choose Our Solid Wall Insulation Services in Ferndale?

Whether you require External Wall Insulation (EWI) or Internal Wall Insulation (IWI), Global Energy Insulation delivers SWIGA-backed heat loss solutions to lower your high energy bills and improve your property's EPC rating across South Wales and the South West. Working seamlessly alongside our sister company, Global Plastering, we guarantee a flawless, fully compliant, end-to-end retrofit finish.

Why Your Talgarth Home Struggles with Heat Loss

If your home was built with solid brick or stone walls, it is likely acting as a thermal bridge, allowing warmth to escape and cold to penetrate your living spaces. This structural issue is a primary cause of high energy bills and persistent damp, condensation, or mould growth. Our team specialises in identifying these specific weaknesses and providing the correct insulation for solid walls, ensuring your property remains warm in the winter and cool in the summer. Whether you reside in a Victorian terrace or a traditional stone cottage, our solutions directly target these inefficiencies.

Enhancing Energy Efficiency and EPC Ratings

Improving your EPC rating is essential for modern compliance, particularly for landlords managing rental properties under MEES regulations. Our PAS 2030 accredited team provides comprehensive retrofit assessments to help you meet these standards, potentially accessing support through schemes like ECO4. By installing high-performance insulation, we not only reduce your carbon footprint but also provide a long-term strategy to combat fuel poverty. Every project we undertake is supported by the Solid Wall Insulation Guarantee Agency (SWIGA), offering you complete peace of mind through an insurance-backed guarantee.

How We Provide a Seamless Retrofit Experience

We pride ourselves on an end-to-end service that respects your property and your time. By coordinating our efforts with our sister company, Global Plastering, we offer a complete package that extends from initial thermal upgrades to the final aesthetic finish. Whether you choose external rendering in a range of high-quality textures or internal wall insulation that requires expert plastering for a smooth finish, our team manages the entire process. From the initial survey to the final coat of paint, you receive professional, locally-based service throughout Talgarth and across the Powys region.

Solid Wall Insulation FAQs

Frequently Asked Questions

Have questions about stopping heat loss, improving your EPC rating, or choosing between EWI and IWI? Find answers about our PAS 2035 accredited solid wall insulation services across South Wales and South West England, South Wales, and the South West.

How long does it take to install external wall insulation?

+

For a standard semi-detached house in Ferndale, the process usually takes between two to three weeks, depending on the weather. This includes the preparation, fixing the insulation boards, and applying the final render finish.

Will I lose much space with internal wall insulation?

+

We use high-performance materials that provide maximum warmth with minimum thickness. While you will lose a few centimetres of room width, the trade-off is a significantly warmer, more comfortable living space that is much cheaper to heat.

Do I need planning permission for EWI?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area or a listed building, or if the insulation significantly changes the look of the street, permission may be required. We can help you understand the requirements for your specific location in Rhondda Cynon Taf or beyond.

Can solid wall insulation stop damp?

+

Yes, it is highly effective at stopping penetrating damp and condensation. By keeping the walls warm, moisture in the air no longer settles on them as water droplets, which prevents the growth of black mould.
