Why Choose Global Energy Insulation for Insulated Render Systems?

How Our Insulated Rendering Solves Thermal Bridging

Many properties in the local area, particularly solid wall homes and non-traditional builds, suffer from thermal bridging where heat escapes through the structure. Our EWI process begins by applying high-performance insulation boards to the exterior, which effectively wraps your home in a thermal blanket. We then apply a premium render—such as silicone, monocouche, or K Rend—which is weather-resistant and breathable. This method stops moisture ingress and prevents the development of black mould, ensuring your living space remains healthy and dry throughout the year.

Meeting PAS 2035 Standards for Your Home

Compliance is at the heart of our service. Whether you are looking to improve your EPC rating for rental compliance or simply want to lower your monthly energy bills, our PAS 2030 accredited team operates strictly within the latest PAS 2035 retrofit standards.

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.
