Why Choose Global Energy Insulation for Insulated Render Systems?

How Our EWI Solutions Reduce Your Energy Bills

Many properties in Monmouthshire, particularly older solid wall homes and non-traditional builds, lose a significant amount of heat through their walls. Our insulated render systems address this by eliminating thermal bridging—the process where cold spots allow heat to escape. Once the insulation boards are professionally installed, we apply a high-quality silicone or monocouche render. This not only traps heat inside your home during the winter but also acts as a robust weather shield, preventing damp, condensation, and black mould growth.

Why Choose Our Accredited Team for Your Home Retrofit?

Choosing the right contractor is vital for long-term peace of mind. We are PAS 2030 accredited and a SWIGA-backed specialist, ensuring that every project comes with an insurance-backed guarantee. As experts in PAS 2035 retrofit standards, we manage the entire process to ensure your home meets current energy efficiency requirements. Whether you are a homeowner looking to improve your EPC rating or a landlord managing HMOs, our team delivers reliable, professional service across the entire Monmouthshire region.

Is Your Property Suitable for Insulated Rendering?

From Victorian terraces and bungalows to Wimpey no-fines or concrete construction homes, our systems are versatile enough to improve almost any building type. External wall insulation is the most effective way to upgrade the EPC rating of a solid wall property, often helping landlords meet MEES compliance deadlines with ease. Because our sister company, Global Plastering, handles all internal finishing, we provide a complete end-to-end service that covers both the exterior aesthetic and the internal comfort of your home.

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.
