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

How Our Cavity Wall Insulation Process Works

Our installation process is thorough, clean, and highly effective. We begin by conducting a comprehensive survey to ensure your property is suitable for cavity wall insulation, checking for structural integrity and identifying any potential moisture issues. Our skilled technicians then drill small, precise holes in the external mortar joints to inject high-quality, government-approved insulation materials directly into the wall cavity. Once the void is completely filled, we carefully fill and match the mortar to ensure the work is virtually invisible. By partnering with our sister company, Global Plastering, we can also provide a seamless finish if any internal repairs are needed during the process.

Why Choose Professional Insulation for Your Barry Home?

Installing cavity wall insulation offers immediate, tangible benefits for homeowners and landlords across the Vale of Glamorgan. By retaining heat, you significantly lower your central heating demand, which helps reduce carbon emissions and helps slash your monthly energy bills. Our services also play a vital role in moisture control, which is essential for preventing damp and condensation in coastal areas. Furthermore, if you are a landlord managing rental properties, our insulation solutions can help you meet essential MEES compliance standards and improve your property's EPC rating, safeguarding your investment against future regulatory changes.

Meeting PAS 2035 Standards and Regulatory Compliance

As a business committed to quality, we operate as a PAS 2035 retrofit specialist. This means we do not just install insulation; we look at the whole-house approach to ensure safety and performance. Whether your property is a traditional home or a more modern build, our team is fully versed in the latest building regulations.

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.
