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.

Is your Penarth home losing heat through the walls?

Solid wall properties often lack the cavity space found in newer builds, meaning heat escapes directly through the brickwork and masonry. This constant thermal leakage leads to cold spots, condensation, and the inevitable growth of black mould. By opting for professional solid wall insulation, you create a continuous thermal envelope around your home. This process significantly improves your EPC rating, which is essential for landlords in the Vale of Glamorgan aiming to meet MEES compliance. Whether you reside in a charming townhouse or a post-war dwelling, our bespoke insulation solutions reduce your reliance on central heating and safeguard your living space against damp.

Professional EWI and IWI installation for your property

We offer two primary routes to improve your home energy efficiency. External Wall Insulation (EWI) involves applying high-quality insulating boards to the exterior of your building, followed by a durable, weather-resistant render finish. This method is perfect for refreshing the look of your home while maintaining or increasing its thermal performance. For properties where the exterior character must remain untouched, such as specific listed buildings or conservation areas, our Internal Wall Insulation (IWI) provides a robust thermal barrier from the inside. We work closely with our sister company, Global Plastering, to ensure that any internal insulation work is finished to a high standard, providing a seamless, end-to-end service for every project.

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.
