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 Home Needs Solid Wall Insulation

Uninsulated solid walls act like a giant heat sink, drawing warmth out of your living space and allowing cold air to penetrate. By choosing professional insulation, you can significantly improve your home energy efficiency and prevent the common issue of thermal bridging, where cold spots lead to condensation and black mould. For landlords in Ystrad Mynach, these upgrades are crucial for meeting modern MEES standards and improving your property EPC rating. Whether you live in a traditional stone-built cottage or a 20th-century non-traditional home, our solutions provide a robust thermal envelope that saves money and protects your building fabric for years to come.

How Does The Installation Process Work

Our process begins with a professional assessment to determine the best approach for your property. We offer External Wall Insulation (EWI), which involves fixing insulating boards to the exterior before applying a high-quality, weather-resistant render. Alternatively, for homes where the original exterior aesthetic must be preserved, we provide Internal Wall Insulation (IWI). As PAS 2035 retrofit specialists, we ensure that every stage of the project is documented and compliant with strict UK building regulations. Our sister company, Global Plastering, is on hand to deliver a perfect, professional finish to any internal surfaces, ensuring you receive a comprehensive, high-quality service from start to finish.

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.
