Why Choose Global Energy Insulation For External Wall Insulation?

How External Wall Insulation Stops Heat Loss

Many properties in Ystradgynlais suffer from poor thermal performance due to solid wall construction, which allows heat to escape rapidly. Our insulation process begins with a thorough site survey to identify areas of thermal bridging. We then apply high-quality insulation boards to the exterior of your building, effectively wrapping your home in a protective thermal envelope. This significantly reduces heat loss and eliminates the cold wall effect that often leads to condensation and black mould growth inside your rooms. By keeping the warmth inside where it belongs, you can drastically lower your heating bills throughout the winter.

Professional Rendering and Finish Options for Your Home

Beyond the thermal benefits, our EWI systems dramatically enhance the exterior aesthetic of your property. We offer a variety of premium, durable finishes including silicone and monocouche rendering that are breathable, weather-resistant, and low-maintenance. These modern finishes not only protect your insulation boarding from the elements but also refresh the appearance of older or weathered homes. As a partner to our sister company, Global Plastering, we provide a truly seamless service, ensuring that any internal finishing or modifications required during the retrofit process are handled with professional care and attention to detail.

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.
