Why Choose Global Energy Insulation for Insulated Render Systems?

How our EWI systems improve your home

Our insulated render process involves installing high-performance insulation boards directly to your exterior walls, which are then finished with a breathable, durable render like silicone or K Rend. This process creates a thermal blanket around your home, effectively eliminating thermal bridging and protecting the structure from the elements. By upgrading your wall insulation, you improve your EPC rating and ensure compliance with modern energy standards. Whether you have a period Victorian terrace, a traditional solid wall home, or a non-traditional build, our systems provide the ideal solution for long-term energy savings and improved comfort.

Quality finishes and aesthetic upgrades

We offer a range of premium finishes to suit every property style, including silicone, monocouche, and K Rend. These materials not only provide excellent thermal efficiency but also deliver a stunning, low-maintenance exterior that adds real value to your property. While Global Energy Insulation focuses on the structural and thermal performance of your external walls, our sister company, Global Plastering, provides expert internal finishing to ensure every aspect of your home renovation is handled to the highest standard. This allows us to provide a seamless, end-to-end service for all our residential and commercial clients.

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.
