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 Should You Consider EWI or IWI for Your Home?

Solid walls account for the largest area of heat loss in older, uninsulated houses. By choosing our External Wall Insulation (EWI) or Internal Wall Insulation (IWI), you create a thermal blanket around your home. This process doesn't just stop the cold; it addresses thermal bridging, prevents condensation, and eliminates black mould, which is often a common issue in damp-prone properties. Whether you live in a classic Victorian terrace or a non-traditional concrete structure, we have the technical expertise to improve your thermal efficiency significantly.

Meeting PAS 2035 Standards for Your Peace of Mind

Navigating modern building regulations can be daunting, but our team simplifies the process. As a PAS 2030 compliant company, we prioritise PAS 2035 standards, ensuring that every retrofit project is managed correctly from assessment to completion. This is vital for landlords needing to reach higher EPC ratings to meet MEES requirements. Our team handles the compliance heavy-lifting, ensuring your insulation project is safe, effective, and compliant with all local authority requirements.

Seamless Service from Our Sister Company Global Plastering

A great insulation project requires a perfect finish. While Global Energy Insulation focuses on the technical thermal upgrades, we work hand-in-hand with our sister company, Global Plastering. This partnership allows us to offer a complete end-to-end service, where internal insulation is followed by professional, high-quality plastering. By keeping the work in-house, we ensure a seamless transition between the structural retrofit and the final aesthetic result, leaving your home looking as good as it feels.

Long-Term Protection with SWIGA Guarantees

We believe in the quality of our work and provide the documentation to prove it. Every solid wall insulation installation we complete is SWIGA (Solid Wall Insulation Guarantee Agency) backed.

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.
