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

How Our Cavity Wall Process Improves Your Home

The process begins with a detailed survey of your property to ensure it is suitable for cavity wall insulation. We assess the condition of your masonry and ensure the structure is free from damp issues. Our installers then drill small, discreet holes in the mortar joints and inject the high-performance insulation material to fill the cavity completely. Once finished, we carefully repair the mortar to match your existing brickwork, leaving your property looking exactly as it did before. We work closely with our sister company, Global Plastering, to ensure any associated internal finishing is handled with expert care.

Why Choose Our PAS 2035 Compliant Retrofit Services?

As a PAS 2035 retrofit specialist, we ensure that every installation adheres to the latest UK building regulations and energy efficiency standards. This compliance is essential for homeowners looking to improve their EPC rating and landlords working to meet MEES requirements for rental properties. Our work is fully backed by the Solid Wall Insulation Guarantee Agency (SWIGA), providing you with long-term protection and peace of mind. We also provide specialist support for those requiring cavity wall extraction, ensuring that failed or contaminated insulation is professionally removed before the new thermal barrier is installed.

Is Your Property Losing Heat Through Uninsulated Walls?

If you notice cold spots on your walls or find that your heating system struggles to keep your home warm, you are likely dealing with thermal bridging. Our insulation treatments are designed to tackle these exact problems, reducing your carbon footprint while slashing your monthly energy expenditure. Whether you live in a traditional semi-detached house or a more modern build, improving the thermal efficiency of your walls is one of the most effective upgrades you can make to any property in the Vale of Glamorgan.

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.
