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?

Unlike traditional sand and cement finishes that are prone to cracking and moisture retention, our high-performance silicone renders are inherently flexible and water-repellent. This breathability is essential for preventing the build-up of damp and condensation, which are common issues in older stone or brick buildings. Furthermore, our systems are UV-resistant and self-cleaning, meaning your property retains its fresh appearance for decades without the need for constant maintenance or painting. Whether you are looking to refresh a tired Victorian terrace or modernise a non-traditional build, our range of colours and textures ensures a bespoke finish.

Expertise in Thermal Efficiency and EPC Improvements

As PAS 2030 accredited experts, we go beyond simple aesthetics. Our rendering services are often integrated with External Wall Insulation to eliminate thermal bridging and slash your energy bills. For landlords managing HMOs or rental properties in Caerphilly, our solutions are a key tool in achieving MEES compliance and improving your property EPC rating. We provide professional assessments to ensure that every installation adheres to current building regulations, offering you peace of mind that your investment is both compliant and future-proofed.

Seamless Service from Global Energy Insulation and Global Plastering

We pride ourselves on being a comprehensive, end-to-end provider for all your property needs. While Global Energy Insulation specialises in high-efficiency external wall treatments and retrofit standards, our sister company, Global Plastering, offers expert traditional plastering services for all your interior requirements. This partnership allows us to manage your home improvements seamlessly, ensuring that the finish inside your home matches the professional quality of our external rendering work. We are CHAS accredited, hold a full waste carriers licence, and are backed by SWIGA to provide insurance-backed guarantees.

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.
