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 our breathable exterior wall coatings?

Traditional sand and cement renders can often crack or absorb moisture over time, leading to damp issues and increased heat loss. Our silicone rendering solutions are designed to be flexible and breathable, allowing water vapour to escape from your walls while preventing rain penetration. This makes them an ideal choice for properties in coastal areas like Barri / Barry where wind-driven rain is a constant factor. Not only does this solve common damp problems, but it also helps to maintain a stable internal temperature, contributing to lower heating bills and a more comfortable living environment.

Expert installation from a PAS 2030 accredited team

Quality assurance is at the heart of our operations. As a PAS 2030 accredited contractor, we ensure that every project we undertake adheres to strict building regulations and industry quality standards. We understand that your home is your most significant asset, which is why we provide full transparency throughout the installation process. Our team handles everything from surface preparation to the final aesthetic finish. Furthermore, by coordinating with our sister company, Global Plastering, we offer a comprehensive end-to-end service that covers both your external insulation needs and internal finishing requirements.

Improving your home energy efficiency in Vale of Glamorgan

One of the most effective ways to improve the EPC rating of a property is through a combination of effective wall insulation and a high-performance render system. Our silicone rendering services are often paired with external wall insulation to eliminate thermal bridging, which is a major cause of cold walls and condensation. Whether you live in a detached house or a semi-detached property, our solutions help modernise your exterior while creating a robust thermal envelope. All of our work is SWIGA-backed and fully insured, giving you the peace of mind that your investment is protected by an Insurance Backed Guarantee.

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.
