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 render for your home?

Unlike traditional sand and cement finishes, modern silicone render is engineered to be highly breathable, flexible, and crack-resistant. This makes it an ideal solution for a variety of property types found in Portishead, from charming period Victorian terraces to modern detached homes. The through-colour technology means you never need to paint your house again, as the material is designed to resist moss, algae, and weather-related damage, keeping your property looking fresh for years to come.

Improving energy efficiency and protecting your investment

Silicone rendering is more than just an aesthetic upgrade; it is a vital part of your home's thermal strategy. When combined with our external wall insulation services, it helps tackle the root causes of high energy bills and heat loss. By creating a thermal envelope around your home, we help reduce thermal bridging and eliminate the conditions where black mould and condensation thrive. Whether you need to improve an EPC rating for a rental property or simply want to lower your heating costs, our services are designed to deliver long-term value and comfort.

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.
