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

Traditional renders often crack or trap moisture, but our advanced silicone systems provide a superior alternative. Silicone render is through-coloured, which means the pigment is mixed throughout the material rather than just applied to the surface. This ensures your home stays looking fresh for years without the need for constant painting. Because the material is vapour-permeable, it allows your building to breathe, effectively preventing the build-up of damp and condensation behind the walls. This is an essential step in maintaining the structural integrity of older properties across the Vale of Glamorgan.

Enhancing Thermal Efficiency and EPC Ratings

Investing in high-quality exterior wall coatings is one of the most effective ways to reduce heat loss in your property. By applying our specialised rendering systems, often in conjunction with our insulation services, we help homeowners significantly improve their home energy efficiency. Improving your EPC rating is not only vital for energy savings but also adds long-term value to your property. Our work is fully aligned with PAS 2030 standards, ensuring that every installation contributes to a warmer, more energy-efficient home that is compliant with current UK building regulations.

Our Comprehensive Approach to Property Improvements

At Global Energy Insulation, we pride ourselves on delivering a complete end-to-end service. Through our close partnership with Global Plastering, we provide a seamless transition between external wall upgrades and internal finishing works.

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.
