Why Choose Global Energy Insulation for Insulated Render Systems?

How Our EWI Systems Solve Cold Home Issues

Our installation process is designed to provide maximum thermal performance while significantly upgrading the external appearance of your property. We first conduct a thorough assessment to address thermal bridging, which is often the cause of cold patches and internal mould growth. Our experts install premium insulation boards directly to the outer walls, which are then finished with high-quality, weather-resistant renders such as silicone or monocouche. This process effectively wraps your home in a protective, thermal blanket that keeps heat inside during the winter and reduces cooling needs in the summer.

Why Choose Our PAS 2030 Accredited Team?

At Global Energy Insulation, we pride ourselves on being fully PAS 2030 accredited, ensuring that every project adheres to the rigorous PAS 2035 retrofit standards. We take the complexity out of home improvements by managing all aspects of compliance, including building regulations and EPC rating requirements. As a CHAS-accredited company, we place safety and quality at the heart of our operations. Furthermore, we work in close partnership with our sister company, Global Plastering, to provide a seamless end-to-end service. Whether you require external rendering or a complete internal finishing solution, our team delivers superior results with a SWIGA-backed insurance-backed guarantee for your peace of mind.

Benefits for Your Property in Rhondda Cynon Taf

Installing an insulated render system is one of the most effective ways to increase your property value and long-term 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.
