Why Choose Global Energy Insulation For External Wall Insulation?

How Professional EWI Transforms Your Property

External Wall Insulation involves applying a thermal insulation layer to the exterior of your building, which is then finished with a high-quality, breathable render. This process eliminates cold spots and thermal bridging, which are common issues in solid wall properties. By wrapping your home in a thermal blanket, we stop heat from escaping through the structure. Once the insulation is in place, our team applies specialist silicone or monocouche rendering. This not only provides a weather-resistant barrier but also gives your home a fresh, modern aesthetic that adds real value to your property.

Is Your Property Suitable for Solid Wall Insulation?

Many homes in Risca, from traditional Victorian terraces to non-traditional builds like Airey or Wimpey no-fines houses, suffer from poor thermal performance. If your house has solid walls, it is likely losing a significant amount of heat through the masonry. Our team is highly experienced in surveying and installing insulation for these specific construction types. We ensure every installation meets current PAS 2035 retrofit standards and UK building regulations, providing you with a safe, compliant, and efficient solution that stands the test of time.

Why Choose Our Accredited Local Installation Team

When you choose Global Energy Insulation, you are opting for a fully PAS 2030 accredited service. We are committed to quality and safety, backed by our status as a SWIGA-registered installer, which means your project is protected by an insurance-backed guarantee. We offer a comprehensive end-to-end service; while we focus on the exterior thermal upgrade and advanced rendering, our sister company, Global Plastering, is available to handle any internal finishing requirements. This partnership ensures that both the inside and outside of your property receive the professional care they deserve.

External Wall Insulation FAQs

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited external wall insulation, EPC improvements, and heat loss reduction services in South Wales and South West England.

Do I need planning permission for external wall insulation in Ferndale?

+

In many cases, EWI falls under "permitted development," but it depends on the property. If you live in a conservation area or if the insulation significantly changes the look of your house compared to your neighbours, you might need to check with Rhondda Cynon Taf council. We can help you understand the local requirements before we start.

How long does the installation take?

+

For a standard semi-detached or terraced home, the process usually takes between 2 to 3 weeks, depending on the weather. Because all the work happens outside, there is very little disruption to your daily life.

Will EWI solve my mould problems?

+

Yes. Most mould in UK homes is caused by "cold spots" on walls where moisture in the air turns into condensation. By insulating the outside of the building, those walls stay warm, preventing the conditions that allow mould to grow.

Can I get a guarantee for the work?

+

Absolutely. We provide SWIGA-backed guarantees, which are industry-recognised and often required by mortgage lenders. This gives you long-term protection and confidence in the quality of our work.
