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 Professional Thermal Upgrades

Many older properties in Swansea lack sufficient insulation, leading to thermal bridging where heat simply escapes through your walls. This not only makes your home uncomfortable during the winter months but also drives up your utility bills significantly. Our solid wall insulation services effectively wrap your home in a protective thermal layer, whether through External Wall Insulation (EWI) or Internal Wall Insulation (IWI). By addressing these heat loss points, we help you improve your EPC rating, ensuring your property meets modern energy standards while creating a warmer, healthier environment for your family.

Expert External and Internal Insulation Services

We offer two primary methods to solve your wall insulation problems. External Wall Insulation (EWI) involves applying high-performance insulation boards to the outside of your property, finished with a weather-resistant render. This is ideal for improving the aesthetic appearance of your home while maximising thermal efficiency. For period properties where preserving the exterior character is essential, our Internal Wall Insulation (IWI) provides an excellent alternative, insulating your rooms from the inside. We work closely with our sister company, Global Plastering, to ensure that any internal work is finished to the highest professional standard, providing a complete, stress-free service from start to finish.

Compliance and Quality You Can Trust

Navigating building regulations and retrofitting standards can be daunting, but you are in safe hands with Global Energy Insulation. We are fully PAS 2030 compliant and offer PAS 2035 retrofit assessment and coordination, ensuring your home upgrade adheres to the latest UK energy efficiency requirements. Our work is SWIGA-backed, providing you with valuable Insurance Backed Guarantees for peace of mind.

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.
