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?

We offer both External Wall Insulation and Internal Wall Insulation to suit your specific property requirements. External wall insulation involves applying high-performance insulation boards to the outside of your home, finished with a protective render. This approach is ideal for enhancing the aesthetic appeal of your building while eliminating thermal bridging. Alternatively, internal wall insulation is perfect for properties where maintaining the external character is essential, such as in certain conservation areas. Our team will conduct a thorough assessment to determine the most effective solution for your home's unique construction.

Achieving PAS 2035 Standards and Better EPC Ratings

Energy efficiency is no longer just a luxury; it is a necessity for homeowners and landlords alike. As a PAS 2030 accredited specialist, we ensure all our work aligns with the latest PAS 2035 retrofit standards. Whether you are aiming to improve your home's EPC rating to meet current MEES compliance or simply looking to lower your monthly bills, our process is built on technical excellence. Being SWIGA-backed means you benefit from the peace of mind that comes with an Insurance Backed Guarantee, protecting your investment for years to come.

A Complete Finish with Global Plastering

We understand that thermal improvements should never come at the cost of your home's interior finish. That is why we collaborate closely with our sister company, Global Plastering. While our insulation specialists focus on the structural and thermal performance of your walls, Global Plastering ensures a seamless, high-quality internal finish that leaves your rooms looking perfect. This end-to-end service ensures you do not need to coordinate multiple contractors, making your home improvement journey in Llanelli stress-free.

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.
