Why Choose Global Energy Insulation for Insulated Render Systems?

How Our Insulated Rendering Improves Your Home

Our process begins with an expert assessment to determine the most effective insulation strategy for your specific wall type. We apply high-grade insulation boards directly to your exterior walls, which are then finished with premium renders such as silicone or monocouche. This process effectively eliminates thermal bridging, a common issue in older housing stock where heat escapes through structural elements. The result is a warmer home in the winter, a cooler living environment in the summer, and a significantly improved EPC rating.

Why Choose Our PAS 2030 Accredited Team

At Global Energy Insulation, we pride ourselves on our technical expertise and commitment to quality. We are PAS 2030 accredited, meaning our installations meet the rigorous standards required for whole-house retrofit projects. Every installation is backed by SWIGA, offering you peace of mind with an insurance-backed guarantee. Being CHAS accredited and fully insured, we handle all compliance requirements, including building regulations and planning considerations for properties in Monmouthshire.

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.
