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

How our insulation process protects your home

Our process begins with a comprehensive assessment to ensure your property is suitable for cavity wall insulation. Our PAS 2030 accredited team inspects your walls for structural integrity and potential damp risks before any material is installed. Using industry-leading insulation materials, we carefully inject the cavity, creating a robust thermal barrier that eliminates cold spots. By adhering to PAS 2035 retrofit standards, we ensure that every installation not only boosts comfort but also complies with the latest UK building regulations, protecting your investment for years to come.

Why upgrade your insulation and EPC rating?

Upgrading to modern cavity wall insulation is one of the most effective ways to improve your home energy efficiency. Many older properties in Brecon suffer from thermal bridging, where heat escapes through uninsulated walls, contributing to higher utility bills and potential condensation issues. By insulating your walls, you can substantially improve your EPC rating, a critical step for landlords needing to meet current MEES compliance. Beyond the financial savings, you will enjoy a drier, healthier living environment free from the black mould often associated with damp, cold wall surfaces.

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.
