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.

Choosing Between External and Internal Wall Insulation

Deciding on the right insulation for your home depends on your specific property type. Our team specialises in both External Wall Insulation (EWI) and Internal Wall Insulation (IWI). EWI involves applying a high-performance insulating layer to the outside of your walls, which is then finished with a weather-resistant render. This is ideal for improving the look of older houses while providing excellent thermal bridging solutions. If external alterations are restricted, we offer IWI, which insulates your rooms from the inside to minimise heat escape without affecting your property's exterior appearance. We assess your home to determine the most effective strategy for your budget and structural needs.

Meeting PAS 2035 Standards for Your Peace of Mind

As a PAS 2030 compliant and PAS 2035 accredited contractor, we take the complexity out of home energy improvements. Whether you are looking to improve your EPC rating to meet landlord MEES requirements or want to participate in the ECO4 scheme, we manage the technical assessment and coordination process. Our work is fully backed by the Solid Wall Insulation Guarantee Agency (SWIGA), providing you with robust, insurance-backed peace of mind for years to come. We hold a Waste Carriers Licence and carry full public liability insurance, ensuring every project is delivered safely and legally.

How Our End-to-End Retrofit Process Works

We simplify the retrofit journey by combining technical expertise with high-quality finishing. Once we carry out a professional retrofit assessment, our team installs the insulation according to strict building regulations. To ensure your home is finished to the highest standard, we work in partnership with our sister company, Global Plastering. This allows us to provide a comprehensive end-to-end service, where all plastering, rendering, and finishing work is handled by our skilled team. This collaboration guarantees that your home is not only warmer but looks immaculate both inside and out.

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.
