Why Choose Global Energy Insulation for Insulated Render Systems?

How Our External Wall Insulation Process Works

Our process begins with a thorough property assessment to determine the most effective strategy for your home. As a PAS 2030 accredited company, we follow the rigorous PAS 2035 retrofit framework to ensure your insulation is installed to the highest industry standards. We fix high-performance insulation boards directly to the external walls, which are then reinforced with a mesh and base coat. Finally, we apply a high-quality decorative finish, such as silicone, monocouche, or K Rend, to provide a durable, weather-resistant exterior. This entire procedure is managed by our expert team, who work with precision to minimise disruption to your daily life.

Key Benefits of Insulated Rendering for Your Property

Investing in insulated rendering provides more than just a fresh look for your home. By improving the thermal efficiency of your external walls, you can drastically reduce heat loss, creating a more comfortable living environment year-round. This is especially vital for landlords who need to improve EPC ratings and meet the latest MEES requirements. Furthermore, our systems help prevent the growth of black mould and condensation by keeping wall surfaces warm. With our SWIGA-backed guarantees, you can rest assured that your investment is protected by comprehensive, insurance-backed coverage.

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.
