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 solid wall insulation is essential for Blaenau Gwent properties

Solid walls are notorious for acting as thermal bridges, allowing precious warmth to escape while letting dampness and condensation creep in. By installing high-performance insulation, you can drastically reduce your energy consumption and lower your monthly heating bills. Beyond comfort, this process is a vital step for landlords in Nantyglo who need to meet MEES compliance and improve the EPC rating of their rental properties. We take a whole-house approach to ensure your property remains breathable and protected against the harsh South Wales weather.

Understanding our PAS 2035 retrofit approach

We operate as a fully PAS 2035 accredited specialist, meaning we don't just add insulation; we assess your property to ensure the right materials are used for your specific building type. Whether you own a Victorian terrace, a stone-built cottage, or a more modern solid wall structure, our team follows strict UK building regulations throughout the installation process. This rigorous approach ensures that your home is not only warmer but also remains structurally sound and healthy for years to come.

Complete end-to-end service from our local team

We pride ourselves on offering a seamless experience from the initial site survey to the final finish. While Global Energy Insulation focuses on the technical aspects of thermal efficiency, our sister company, Global Plastering, handles all internal finishes and rendering requirements.

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.
