Why Choose Global Energy Insulation for Insulated Render Systems?

How Our EWI Installation Process Works

Our installation process is designed to deliver maximum thermal performance with minimal disruption. After an initial survey, we fix high-quality insulation boards directly to your external walls. These are then finished with a specialist base coat, a reinforcing mesh, and your chosen decorative finish, such as silicone or monocouche render. As PAS 2030 accredited installers, we follow strict industry protocols at every stage, ensuring the system is fitted to the highest standards. This approach creates a thermal envelope that keeps heat inside during winter and maintains a comfortable temperature during warmer months.

Is Your Property Suitable for Insulated Rendering?

Whether you own a traditional Victorian terrace, a non-traditional Wimpey no-fines build, or a modern bungalow, our insulated render systems can be tailored to suit your specific construction type. Many older properties in Carmarthenshire suffer from solid wall heat loss, which traditional heating systems struggle to overcome. Our solutions are designed to address these cold wall issues directly, helping you improve your EPC rating and meet current MEES standards. We also handle the technical aspects of building regulations, ensuring that your home improvement is compliant and future-proofed.

Transform Your Home with Our Dual Service Approach

One of the key benefits of choosing Global Energy Insulation is our ability to offer a comprehensive, end-to-end home improvement service. While our team focuses on the external thermal efficiency and rendering, our sister company, Global Plastering, manages all internal finishes to a professional standard. This combined expertise means you do not need to coordinate multiple contractors. From the initial insulation boards on your exterior to the final skim inside your living space, we ensure a seamless and stress-free project from start to finish.

We are fully PAS 2030 compliant and operate as PAS 2035 retrofit specialists, meaning we have the expertise to manage your project correctly from a regulatory standpoint.

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.
