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 EWI and IWI for your home?

Selecting the right method for heat loss reduction depends on your property type and personal preference. External Wall Insulation (EWI) involves applying high-performance insulation boards to the outside of your property, finished with a protective render. This is ideal for improving the aesthetic of your home while minimising disruption to your interior. Alternatively, Internal Wall Insulation (IWI) is perfect for homes where maintaining the external brickwork or period features is essential. Our team provides detailed assessments to help you choose the best solution to improve your EPC rating and resolve thermal bridging.

The benefits of our PAS 2035 accredited services

We pride ourselves on being a SWIGA-backed and PAS 2030 compliant installer, ensuring every project meets the most stringent UK building regulations. For landlords in Rhisga and Risca, our services are vital for meeting current MEES requirements, ensuring your rental properties are compliant and attractive to tenants. Our work goes beyond simple installation; we focus on whole-house comfort. By tackling the root causes of heat loss, we help you save money on monthly heating costs while creating a healthier, condensation-free living environment.

Comprehensive support from assessment to internal finish

We offer a truly end-to-end service for residents in South Wales. Our team handles everything from initial PAS 2035 retrofit assessments to the final decorative rendering. We understand that insulation is only one part of a home improvement project; that is why our sister company, Global Plastering, provides seamless traditional plastering services for all internal work. This synergy allows us to deliver a high-quality, professional finish that integrates perfectly with your existing home decor, giving you complete peace of mind throughout the renovation process.

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.
