Why Choose Global Energy Insulation for Insulated Render Systems?

How Our EWI and Rendering Process Works

Our process begins with a professional assessment to ensure your property is suitable for external wall insulation. As a PAS 2030 and PAS 2035 accredited team, we manage the entire retrofit journey, from initial design to final installation. We apply high-performance insulation boards to your exterior walls, followed by a breathable, weather-resistant render finish. Whether you prefer the clean look of modern silicone, K Rend, or a durable sand and cement finish, we ensure a flawless application. We carefully manage thermal bridging, ensuring every corner of your home is protected against cold spots and condensation.

Why Choose Insulated Rendering for Your Property

Investing in insulated render systems delivers immediate and lasting benefits. Beyond slashing your annual energy costs, you will see a dramatic improvement in your home's EPC rating, which is essential for landlords meeting current MEES requirements. These systems also provide a fresh, modern aesthetic, effectively weatherproofing your exterior walls against the harsh Welsh climate. By choosing our team, you benefit from our full suite of expertise. Through our sister company, Global Plastering, we also provide professional internal finishing services, ensuring a seamless experience from the outside in.

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.
