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 Your Home

Unlike modern cavity walls, solid wall properties lack the insulation gap needed to trap heat. This lack of thermal barrier leads to cold walls, damp patches, and expensive heating requirements. By installing professional insulation, you can significantly improve your home energy efficiency and stop heat from escaping through your walls. Whether you live in a classic Victorian terrace or a non-traditional build, our insulation treatments provide a lasting solution to thermal bridging, helping you maintain a consistent, comfortable temperature throughout the year.

Professional PAS 2035 Retrofit and Compliance

Navigating the complexities of building regulations and energy standards can be daunting. As a PAS 2030 accredited company, we offer comprehensive PAS 2035 retrofit coordination to ensure every project meets the latest UK building standards. We assist landlords and homeowners in Llantrisant with achieving necessary improvements to their EPC ratings to meet current MEES compliance. From managing local planning requirements to ensuring all work is fully certified, we take the stress out of property upgrades.

What Is the Process for Installing Solid Wall Insulation?

Our process begins with a detailed survey to assess your property type and thermal needs. We then determine whether External Wall Insulation (EWI) or Internal Wall Insulation (IWI) is the most suitable option for your specific building. Our skilled team handles the installation with care, ensuring minimal disruption to your daily life. Because we partner closely with our sister company, Global Plastering, we offer a complete, end-to-end service that includes high-quality internal finishing and aesthetic upgrades, leaving your home looking better than ever.

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.
