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 home?

Silicone rendering offers a superior alternative to traditional sand and cement finishes. These modern systems are through-coloured, meaning you will never need to paint your walls again, saving you time and money on maintenance. The material is inherently flexible, allowing it to move with your building to prevent the cracking often seen in older render types. Beyond the clean, contemporary look, our silicone systems act as a protective barrier against the Welsh weather, effectively stopping moisture penetration and preventing the damp issues that often plague solid wall properties in Chepstow.

Our expertise in PAS 2035 and building standards

Compliance is at the heart of everything we do at Global Energy Insulation. As a PAS 2030 accredited company, we manage all PAS 2035 retrofit requirements, ensuring every installation meets the latest government standards for energy efficiency. We understand the specific needs of properties in Monmouthshire, including those in conservation areas that may require special planning advice or specific material choices. Our team ensures that your project is fully compliant with building regulations, providing you with peace of mind that your home improvements are safe, efficient, and professionally documented.

How do we deliver a complete finish?

We pride ourselves on providing a seamless end-to-end service for our clients. While Global Energy Insulation focuses on the external thermal efficiency and protective rendering, our sister company, Global Plastering, handles all internal finishing requirements. This partnership allows us to manage your entire project, from the initial survey to the final interior touches. We are proud to be SWIGA-backed, offering insurance-backed guarantees on all external work. With our CHAS accreditation, full public liability insurance, and a professional team, you can trust us to deliver high-quality results registered under company number 05875199.

What is the process for getting your home rendered?

Every project begins with a thorough site survey to assess the condition of your walls and determine the best insulation or rendering system for your building type. Once we have established your specific needs, our skilled technicians prepare the substrate to ensure perfect adhesion. We then apply the base coat with reinforced mesh, followed by the chosen silicone or monocouche topcoat. We handle all site safety and waste management using our own waste carriers licence, ensuring your property is left clean and tidy once the work is complete.

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.
