Why Choose Global Energy Insulation for Insulated Render Systems?

How Our External Wall Insulation Process Works

Our installation process is designed to be seamless, starting with a comprehensive survey to ensure your property is suitable for EWI. We apply high-grade insulation boards directly to the external facade, which are then reinforced and finished with a durable, weather-resistant render. This approach effectively tackles thermal bridging, the primary culprit for heat escaping from solid wall homes. By using premium materials like silicone and K Rend, we ensure your home remains breathable, protected from damp, and significantly more energy-efficient throughout the year.

Why Choose Global Energy Insulation for Your Retrofit?

We pride ourselves on being the local experts for PAS 2030 accredited energy improvements in Monmouthshire. Being SWIGA-backed means every installation comes with an Insurance Backed Guarantee, providing you with total peace of mind. While our team focuses on the external thermal envelope, our sister company, Global Plastering, manages all necessary internal finishing. This end-to-end service ensures your home receives a complete, professional renovation from start to finish, backed by our status as a CHAS-accredited and fully insured contractor.

Can Insulated Render Help Your EPC Rating and Compliance?

For landlords and homeowners alike, hitting energy efficiency targets is becoming increasingly critical. Our insulated render systems are specifically designed to help solid wall, Victorian, and non-traditional properties significantly improve their EPC rating. Whether you need to meet MEES requirements for rental properties or simply want to future-proof your home against rising costs, our PAS 2035 compliant retrofit services ensure full adherence to current UK building regulations. We handle the technical complexities so you can enjoy a warmer, compliant property without the stress.

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.
