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

How Our Insulation Process Improves Your Home

Our installation process is designed to be efficient, clean, and highly effective. First, our PAS 2030 accredited team conducts a thorough survey to ensure your property is suitable for cavity wall insulation. We then drill small, precise entry points into the external mortar joints to inject high-quality thermal material into the cavity. Once the space is filled, these holes are colour-matched and pointed so they are virtually invisible. This process creates a continuous thermal blanket around your home, effectively stopping heat from escaping and preventing the damp issues often caused by thermal bridging.

Why Choose Our PAS 2030 Accredited Local Team

When you choose Global Energy Insulation, you are partnering with an expert team committed to the highest industry standards. We are fully PAS 2030 compliant and experienced in meeting PAS 2035 retrofit requirements, ensuring your home upgrades are safe, efficient, and future-proof. Because we work closely with our sister company, Global Plastering, we can manage every aspect of your home improvement, including any necessary internal finishing or plastering repairs. We take pride in being a trusted, fully insured, and CHAS accredited contractor serving the Y Blaenau and Blaina community.

Enhancing Energy Efficiency and EPC Ratings

Improving the energy efficiency of your property is essential for both comfort and long-term value. For landlords in Blaenau Gwent, meeting the current MEES (Minimum Energy Efficiency Standards) is a legal requirement for renting out properties. Our cavity wall insulation services are an excellent way to improve your EPC rating and ensure compliance. Beyond the regulatory benefits, our work is SWIGA-backed, meaning you receive an insurance-backed guarantee for your peace of mind. Investing in your home now protects you against the rising costs of energy in the coming winter months.

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.
