Why Choose Global Energy Insulation For External Wall Insulation?

How Our EWI System Transforms Your Property

Our installation process begins with a professional assessment to ensure your property meets PAS 2035 retrofit standards. We apply high-grade insulating boards to the exterior of your building, effectively sealing the thermal envelope. Once the insulation is securely fitted, we apply a specialist render finish, such as silicone or monocouche, which provides a weather-tight, breathable barrier. This process not only stops heat loss at the source but also revitalises the external appearance of your property, leaving it with a fresh, modern finish.

Why Choose Our Professional Installation Services

When you choose Global Energy Insulation, you are opting for a complete, end-to-end service. While our team focuses on expert insulation and exterior weatherproofing, our sister company, Global Plastering, provides comprehensive internal finishing to ensure your project is completed to the highest standard. We are PAS 2030 accredited and a SWIGA-backed installer, meaning every project we deliver comes with an insurance-backed guarantee. We handle everything from the initial technical survey to final certification, ensuring full compliance with UK building regulations.

Is Your Home Losing Heat Through Solid Walls?

Many properties in Caerphilly are built with solid walls that lack cavity insulation, leading to significant heat loss and increased susceptibility to damp and mould. External wall insulation is the most effective solution for these structures, creating a thermal barrier that retains heat, lowers your monthly fuel costs, and helps you achieve a better EPC rating. By addressing thermal bridging, we help you create a warmer, healthier living environment that remains comfortable throughout the coldest winter months.

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.
