Why Choose Global Energy Insulation for Insulated Render Systems?

How Our External Wall Insulation Process Works

Our process begins with a professional assessment to ensure your property is suitable for insulated rendering. We apply high-quality insulation boards directly to the external facade, which are then finished with a breathable, durable render such as silicone, monocouche, or K Rend. This approach effectively wraps your home in a protective thermal blanket, eliminating thermal bridging and preventing the cold wall issues often found in Victorian, solid wall, or non-traditional properties like Wimpey no-fines homes.

Why Choose Insulated Rendering for Your Property

Choosing an insulated render system is a smart investment that delivers immediate results. Beyond drastically reducing heat loss, our systems provide a clean, modern aesthetic that rejuvenates tired brickwork. These systems also act as a shield against damp and condensation, which are common culprits for black mould growth. By choosing our PAS 2030 accredited services, you gain the peace of mind that your home is fully compliant with modern building regulations and PAS 2035 retrofit standards.

Complete Retrofit and Finishing Services in North Somerset

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.
