Why Choose Our Silicone Rendering Services in South Wales?

Based in Ferndale and proudly serving a 60-mile radius across South Wales and South West England, Global Energy Insulation is your leading PAS 2030 accredited and SWIGA-backed specialist. Our premium silicone rendering and External Wall Insulation (EWI) systems provide the ultimate cold wall treatment—eliminating thermal bridging, stopping cold draughts, and dramatically helping to improve your home's energy efficiency and EPC rating. Plus, working seamlessly alongside our sister company, Global Plastering, we provide a complete end-to-end finish, from robust external weatherproofing to flawless internal traditional plastering.

Why Choose Silicone Render for Your Newport Home

Unlike traditional sand and cement, silicone render is highly flexible, meaning it is significantly more resistant to cracking as your building settles. This advanced material is through-coloured, which means you can say goodbye to the recurring cost and hassle of painting your exterior walls every few years. Beyond the aesthetic benefits, our rendering solutions act as a critical barrier against moisture ingress and damp, helping to prevent the thermal bridging issues that often lead to heat loss in older, solid wall properties. By improving your home's thermal envelope, you are also making a significant step towards a better EPC rating.

Expertise and Accreditation You Can Trust

We take quality seriously at Global Energy Insulation. As PAS 2030 accredited specialists, we work strictly in accordance with PAS 2035 standards to ensure every project is safe, compliant, and durable. We are also CHAS accredited and hold a valid Waste Carriers Licence, giving you complete peace of mind that your project is in professional hands. Furthermore, we provide SWIGA-backed guarantees for our solid wall insulation and rendering work, ensuring your investment is protected for the long term.

Complete External and Internal Finishing Solutions

One of the key advantages of working with us is our ability to offer a complete, end-to-end service. Through our sister company, Global Plastering, we provide expert internal plastering services that perfectly complement our external silicone rendering and wall insulation work. Whether you are undertaking a full home renovation or a targeted efficiency upgrade, our partnership ensures that both the internal surfaces and the external facade of your property are finished to the highest possible standard, saving you the stress of coordinating multiple trades.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited silicone rendering, weatherproofing, and energy-efficient exterior finishes across South Wales and South West England, South Wales, and the South West.

Why Choose Global Energy Insulation for Your Project?

+

Choosing a contractor is about more than just the price. You need a team that has the right credentials and a track record of quality. We are CHAS accredited and hold a full Waste Carriers Licence, ensuring your property is kept safe and tidy throughout the project.
One of our biggest strengths is our partnership with our sister company, Global Plastering. While Global Energy Insulation handles the external rendering, insulation, and retrofit coordination, Global Plastering provides expert internal plastering. This means we offer a true end-to-end service. We can insulate and render the outside, and then step inside to handle the drylining and finishing, saving you the hassle of managing multiple trades.
Every solid wall insulation project we undertake is backed by a SWIGA (Solid Wall Insulation Guarantee Agency) insurance-backed guarantee, giving you total peace of mind that your investment is protected.

How long does silicone rendering take to finish?

+

Most domestic projects take between 1 and 2 weeks, depending on the size of the house and the weather. We need dry conditions to apply the final thin-coat layer to ensure a perfect, streak-free finish.

Can I apply silicone render over my old render?

+

In some cases, yes, if the original render is structurally sound. However, we usually recommend stripping back to the brickwork or using a base coat with mesh reinforcement to prevent old cracks from showing through the new surface.

Is silicone rendering more expensive than sand and cement?

+

The initial cost is higher because the materials are far more advanced. However, when you factor in that you never have to paint it and it lasts much longer without cracking, it is a far more cost-effective choice for long-term home improvement.

Does silicone render stop damp?

+

Yes. By creating a waterproof, breathable barrier, it prevents driving rain from soaking into your walls, which is a leading cause of penetrating damp in South Wales homes.
