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 strictly adhere to PAS 2035 retrofit standards, meaning every step is carefully planned to prevent condensation and structural issues. Once the insulation boards are securely fixed to your exterior walls, we apply a high-quality base coat and a breathable silicone or monocouche render. This dual-layer approach effectively eliminates thermal bridging while providing a durable, weather-resistant, and aesthetically pleasing finish.

The Benefits of Upgrading Your Home in Caerphilly

Investing in an insulated render system provides significant long-term advantages. By wrapping your property in a thermal blanket, you drastically reduce heat loss, which translates to lower monthly heating bills and a consistently warmer home during the winter. These systems also protect against damp and mould growth, which is a common issue in older, solid-walled buildings. Furthermore, our finishes are available in a variety of colours and textures, allowing you to modernise the exterior appearance of your property while increasing its market value and overall energy efficiency.

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.
