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 breathable silicone rendering for your property?

Silicone render is an ideal solution for homes in Swansea because of its inherent flexibility and water-repellent properties. Unlike traditional sand and cement finishes that can crack under thermal stress, our high-quality silicone systems move with your building, effectively preventing structural cracks and stopping moisture ingress. This makes it an essential component for effective weatherproofing. By creating a sealed yet breathable barrier, we help manage condensation levels and contribute to long-term heat loss reduction, ensuring your home remains comfortable and dry regardless of the season.

Expert installation compliant with PAS 2035 standards

As PAS 2030 accredited specialists, we understand that external improvements must adhere to strict quality and safety guidelines. Every rendering project we undertake is managed in line with PAS 2035 retrofit standards where applicable, ensuring that our work aligns with the latest UK building regulations. We are CHAS registered and SWIGA-backed, meaning your investment is protected by comprehensive insurance-backed guarantees. From Victorian terraces to modern commercial units, we apply rigorous standards to every project to help you achieve a better EPC rating and greater energy efficiency.

A seamless end-to-end service for your home

At Global Energy Insulation, we pride ourselves on being more than just external wall specialists. By working in close partnership with our sister company, Global Plastering, we provide a complete, end-to-end renovation service. If your project requires internal plastering alongside external wall insulation or rendering upgrades, our team manages the entire process smoothly. This holistic approach ensures that every aspect of your home, from the structural exterior to the interior finishing, meets the highest quality standards without the stress of coordinating multiple contractors.

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.
