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 choose between Internal and External Wall Insulation?

Not every home in Abercarn requires the same approach. External Wall Insulation (EWI) involves applying a layer of insulating material to the outside of your property, which is then finished with a high-quality render. This is an excellent way to improve thermal efficiency while upgrading your home's exterior aesthetic. If your home has specific planning restrictions or you prefer to maintain the original brickwork, we also offer Internal Wall Insulation (IWI). This process allows us to insulate your walls from within, providing a powerful solution to thermal bridging without altering the building's exterior appearance.

How our end-to-end retrofit process works

We take the complexity out of home energy upgrades. As a PAS 2030 compliant team, we manage your project from the initial retrofit assessment through to final certification. Once our assessment is complete, our expert installers carry out the insulation work with minimal disruption. Because we want every job to be perfect, our sister company, Global Plastering, handles all internal finishing work. This provides you with a seamless, end-to-end service, ensuring your walls are not only thermally efficient but also beautifully finished.

Local compliance and the benefits for your home

Upgrading your insulation is about more than just comfort; it is a vital step in meeting modern UK building regulations and MEES requirements. By reducing heat loss, you can significantly slash your heating bills and prevent common issues such as condensation and black mould. Our work is SWIGA-backed, offering you peace of mind with insurance-backed guarantees. Whether you own a terraced home in the heart of Abercarn or a detached property in the wider Caerphilly area, our CHAS-accredited team ensures your home is warm, dry, and energy-efficient for years to come.

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.
