Why Choose Global Energy Insulation for Insulated Render Systems?

Why Choose Our Professional EWI and Rendering Services?

Our insulated render systems offer a dual-benefit solution. By installing external wall insulation (EWI) and finishing it with durable silicone or monocouche render, we create a thermal envelope around your property that eliminates thermal bridging and prevents damp issues. Whether you own a traditional terraced house or a non-traditional build, our systems significantly improve your home’s energy efficiency. We pride ourselves on delivering a finish that is not only highly efficient but also aesthetically pleasing, increasing the overall value and curb appeal of your property.

How Does Our PAS 2030 Accredited Process Work?

Quality and compliance are at the heart of everything we do. As PAS 2030 accredited specialists, we follow strict PAS 2035 retrofit standards to ensure every installation meets the highest UK building regulations. We start by conducting a thorough survey to assess the thermal requirements of your home. Following this, we install high-grade insulation boards to the exterior of your property, which are then covered with a breathable, weather-resistant render. This process is seamless and managed entirely by our qualified team, ensuring a high-quality finish every time.

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.
