Global Energy Insulation is a premier PAS 2035 retrofit specialist helping homeowners across Trecceln, Newbridge, and the wider Caerphilly area tackle the challenge of heat loss.

By installing professional solid wall insulation, we help you transform your home into a warmer, more cost-effective living space while significantly reducing your carbon footprint.

Why Choose Our Solid Wall Insulation Services in Ferndale?

Whether you require External Wall Insulation (EWI) or Internal Wall Insulation (IWI), Global Energy Insulation delivers SWIGA-backed heat loss solutions to lower your high energy bills and improve your property's EPC rating across South Wales and the South West. Working seamlessly alongside our sister company, Global Plastering, we guarantee a flawless, fully compliant, end-to-end retrofit finish.

How Our Insulation Solutions Stop Heat Loss

We offer both External Wall Insulation and Internal Wall Insulation to suit your specific property requirements. External wall insulation involves applying a thermal layer to the outside of your home, followed by a durable, weather-resistant render. This is excellent for thermal bridging solutions as it wraps the building in a protective blanket. Internal wall insulation is an ideal alternative when preserving the original character of the exterior facade is necessary. Our team assesses your home to ensure the most effective method is used to keep warmth exactly where it belongs: inside.

Why Choose Professional Retrofit for Your Property

Improving your home energy efficiency is about more than just comfort; it is a vital step in maintaining property value and meeting modern standards. Our services directly contribute to an improved EPC rating, which is essential for landlords navigating current MEES requirements. By eliminating cold spots and preventing damp and condensation, we protect the structural integrity of your home. As a fully PAS 2030 compliant team, we ensure every aspect of your project adheres to strict UK building regulations, giving you total peace of mind.

Complete End-to-End Service from Our Expert Team

What sets us apart is our holistic approach to your property renovation. While Global Energy Insulation focuses on high-performance thermal retrofitting and rendering, our sister company, Global Plastering, ensures the perfect finish for any internal work required. We handle everything from the initial PAS 2035 retrofit assessment and coordination to the final aesthetic touches. Because we are SWIGA-backed and CHAS-accredited, our clients know they are receiving a service that is both technically sound and supported by industry-leading insurance-backed guarantees.

Solid Wall Insulation FAQs

Frequently Asked Questions

Have questions about stopping heat loss, improving your EPC rating, or choosing between EWI and IWI? Find answers about our PAS 2035 accredited solid wall insulation services across South Wales and South West England, South Wales, and the South West.

How long does it take to install external wall insulation?

+

For a standard semi-detached house in Ferndale, the process usually takes between two to three weeks, depending on the weather. This includes the preparation, fixing the insulation boards, and applying the final render finish.

Will I lose much space with internal wall insulation?

+

We use high-performance materials that provide maximum warmth with minimum thickness. While you will lose a few centimetres of room width, the trade-off is a significantly warmer, more comfortable living space that is much cheaper to heat.

Do I need planning permission for EWI?

+

In many cases, EWI falls under "permitted development." However, if you live in a conservation area or a listed building, or if the insulation significantly changes the look of the street, permission may be required. We can help you understand the requirements for your specific location in Rhondda Cynon Taf or beyond.

Can solid wall insulation stop damp?

+

Yes, it is highly effective at stopping penetrating damp and condensation. By keeping the walls warm, moisture in the air no longer settles on them as water droplets, which prevents the growth of black mould.
