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 Through-Coloured Silicone Render for Your Home

Silicone render is a premium, thin-coat system that provides a flexible, crack-resistant finish for almost any property type, including solid wall, Victorian, or modern construction. Unlike traditional sand and cement, silicone rendering is through-coloured, meaning it does not require painting and remains vibrant for many years. This system is exceptionally hydrophobic, meaning it actively repels water while allowing the building to breathe. By reducing moisture penetration, you can effectively tackle damp issues and prevent structural decay, leading to a healthier internal environment and a significant reduction in energy bills.

Meeting PAS 2035 Standards and Building Regulations

Ensuring your property remains compliant with UK building regulations is at the core of what we do. As a PAS 2030 accredited business, we understand the complexities of modern whole-house retrofit standards, including PAS 2035 requirements. Whether your property is a traditional solid wall house requiring thermal upgrades or a modern unit needing aesthetic renovation, we provide expert guidance on planning permissions and conservation area restrictions. We ensure that every project is completed to the highest standard, protecting the integrity of your home while helping to improve your EPC rating.

Integrated Services with Global Plastering

We take pride in offering a comprehensive, end-to-end service for all our clients in Monmouthshire. While Global Energy Insulation focuses on your external wall insulation and high-performance rendering needs, our sister company, Global Plastering, is on hand to manage any internal plastering or finishing requirements. This partnership allows us to manage your home improvements seamlessly, ensuring that both the exterior of your property and its internal living spaces receive the professional attention they deserve from a single, trusted team.

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.
