Why Choose Global Energy Insulation for Insulated Render Systems?

How Our EWI Systems Solve Heat Loss

Many older properties in Llantrisant suffer from poor thermal performance due to solid walls or non-traditional construction methods. Our insulated render process works by fixing high-performance insulation boards to the exterior of your building, which are then finished with a durable, weather-resistant render. This approach significantly reduces thermal bridging, which is the primary cause of cold spots and internal condensation. By wrapping your home in a protective, thermal layer, we effectively stop heat from escaping through the walls, allowing your heating system to run more efficiently and lowering your monthly energy costs.

Transform Your Home with Professional Rendering

Beyond the clear thermal benefits, our rendering solutions provide a fresh, modern exterior for your property. We work with a variety of high-quality finishes, including silicone and monocouche renders, which are breathable and resistant to cracking. Whether you live in a traditional Victorian terrace or a modern concrete build, our finishes can be customised to suit your aesthetic preferences. Because we work closely with our sister company, Global Plastering, we can provide a complete end-to-end service, ensuring that both your home’s external thermal envelope and internal plastering needs are handled by our expert, coordinated team.

FAQ

Frequently Asked Questions

Answers to common questions about our PAS 2030 accredited insulated render systems, stopping thermal bridging, and upgrading home energy efficiency with external wall insulation (EWI) in South Wales and South West England and across South Wales.

Will an insulated render system stop the damp in my house?

+

Yes. Most damp in UK homes is actually condensation caused by "cold bridges" on the walls. By insulating the outside of the building, the internal walls stay warm, which prevents moisture in the air from turning into water droplets and mould.

How long does the installation take?

+

For a standard semi-detached house, the process usually takes between 2 to 3 weeks, depending on the weather. Because it is an external process, there is very little disruption to your daily life inside the house.

Do I need planning permission for External Wall Insulation?

+

In many cases, EWI falls under "Permitted Development." However, if you are changing the appearance of the house significantly, or if you live in a conservation area or a listed building, you might need it. We help you navigate these local authority requirements to keep everything above board.

What is the difference between Silicone Render and K Rend?

+

K Rend is a brand that produces various types of render, including Monocouche. Silicone render is a specific type of finish that is highly breathable and water-repellent. It stays cleaner for longer because dirt struggles to grip the surface, and it is less likely to crack because it stays flexible.
