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

Why Invest in Cavity Wall Insulation for Your Property?

Many homes in Carmarthenshire have uninsulated wall cavities that act as a thermal bridge, allowing precious heat to escape through the walls. By professionally filling these cavities, we create a thermal blanket around your home. This process not only keeps your living area warmer during the winter months but also plays a vital role in preventing damp and condensation issues. Whether you live in a traditional semi-detached house or a more modern property, effective insulation is one of the most cost-effective ways to improve your home energy efficiency rating.

We pride ourselves on our technical expertise, ensuring every installation complies with current UK building regulations and PAS 2035 retrofit standards.

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.
