Why Choose Global Energy Insulation for Cavity Wall Insulation in Ferndale & Rhondda Cynon Taf?

How Our Cavity Wall Insulation Process Works

Our process begins with a professional assessment to ensure your property is suitable for insulation. We check for structural integrity and existing damp issues, adhering strictly to PAS 2035 retrofit standards. Our team then injects high-quality insulation material into the cavity, which effectively fills the voids and eliminates thermal bridging. This simple but highly effective measure drastically reduces heat escape through the walls, keeping your rooms warmer during the winter months.

Why Choose Our PAS Accredited Insulation Services?

We pride ourselves on our technical expertise and commitment to quality. As a PAS 2030 accredited business, we operate to the highest UK building regulations, ensuring every project is delivered safely and effectively. Every installation is backed by the Solid Wall Insulation Guarantee Agency (SWIGA), providing you with an insurance-backed guarantee for long-term peace of mind. We also hold a valid Waste Carriers Licence and carry full public liability insurance to protect your property and our staff.

Expert Support for Landlords and Commercial Clients

If you are a landlord in Aberpennar or Mountain Ash, meeting the current Minimum Energy Efficiency Standards (MEES) is essential for your rental portfolio. We help you achieve the required EPC rating to keep your properties compliant and attractive to tenants. Our services extend beyond domestic homes; we also work with schools, offices, and commercial warehouses to provide large-scale energy efficiency improvements. We work in tandem with our sister company, Global Plastering, to ensure that if any internal repairs or finishing works are required after the insulation process, you receive a complete, end-to-end service under one roof.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited cavity wall insulation, reducing heat loss, and lowering winter energy bills in South Wales and South West England, Rhondda Cynon Taf, and across South Wales.

How do I know if my home in Ferndale has cavity walls?

+

Generally, houses built after the 1920s have a cavity—a gap between two layers of brick. You can usually tell by the brick pattern; if all the bricks look the same length, it’s likely a cavity wall. If some bricks look shorter (the ends of the bricks), it is probably a solid wall. We can confirm this for you with a quick survey.

Will cavity wall insulation cause damp?

+

When installed correctly by a PAS 2030 accredited professional, it actually helps prevent damp by reducing condensation on cold walls. We always check for existing issues and ensure your home has the right ventilation before we start.

How much money can I save on my bills?

+

According to the Energy Saving Trust, the average semi-detached house can save significantly on heating costs every single year. Given the current energy prices in the UK, the insulation often pays for itself in just a few years.
