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

How Our Insulation Process Reduces Your Heat Loss

Our installation process begins with a thorough assessment to ensure your property is suitable for cavity wall insulation. We carefully inspect your walls for damp, structural integrity, and existing insulation. Using high-quality materials, we inject insulation into the gap between your inner and outer masonry walls, creating an effective thermal barrier that keeps heat inside during the winter and prevents it from entering during the summer. This process is essential for tackling thermal bridging, a common issue in older or poorly insulated properties.

Why Choose Global Energy Insulation for Your Retrofit?

Choosing the right installer is critical for long-term performance and regulatory compliance. We are fully PAS 2030 accredited and operate in line with rigorous PAS 2035 retrofit standards. Every project we undertake in Caerllion and Caerleon is SWIGA-backed, providing you with an insurance-backed guarantee for complete peace of mind. We are also CHAS accredited, fully insured, and hold a valid Waste Carriers Licence, ensuring that our site management is as professional as our technical work.

Improving Energy Ratings for Landlords and Homeowners

For landlords in Newport, meeting MEES requirements is more important than ever. Improving your property's EPC rating is a cost-effective way to ensure compliance while making your rental units more attractive to tenants. Whether you own a Victorian terrace, a semi-detached property, or a non-traditional build like a Wimpey no-fines house, our tailored solutions provide the necessary thermal upgrade. By working alongside our sister company, Global Plastering, we offer a comprehensive end-to-end service that covers everything from the initial insulation to any internal finishing requirements.

Frequently Asked Questions About Cavity Wall Insulation

Many residents in Caerllion and Caerleon ask how long the installation takes. Most standard properties can be completed within a day with minimal disruption. Another common concern is whether this service helps with damp; when installed correctly by experts, insulation reduces cold spots where condensation often forms, thereby helping to prevent black mould. If you have questions about whether your specific property type is suitable, our team is ready to provide expert guidance.

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.
