Why Choose Global Energy Insulation For External Wall Insulation?

How our EWI process works for your home

Our installation process begins with a thorough assessment to ensure your property is suitable for external wall insulation. As a PAS 2035 accredited team, we manage the entire project from initial design to final finish. We apply high-performance insulation boards to the exterior of your building, which are then reinforced and covered with a breathable, weather-resistant render. This creates a protective thermal envelope around your home, effectively stopping thermal bridging and trapping heat inside where it belongs.

Key benefits of choosing external wall insulation

The primary advantage of EWI is a dramatic reduction in heat loss, which directly translates to lower monthly energy bills. Beyond thermal performance, our systems help improve your property EPC rating, a critical factor for landlords working towards MEES compliance. The process also acts as a damp reduction measure, preventing condensation and black mould growth inside your rooms. Furthermore, with choices like silicone or monocouche rendering, you can achieve a modern, aesthetic upgrade that significantly boosts your property value and kerb appeal.

Are you concerned about compliance and regulations?

Navigating UK building regulations can feel overwhelming, but our team handles every detail for you. As PAS 2030 compliant contractors, we ensure every installation meets the highest industry standards. Whether your property is a traditional terrace, a detached home, or a non-traditional build like an Airey or Wimpey no-fines house, we provide the technical expertise required for a successful retrofit. We also work closely with our sister company, Global Plastering, to provide a complete end-to-end service, ensuring the transition between your external improvements and internal spaces is handled by a single, trusted team.

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.
