Why Choose Global Energy Insulation for Insulated Render Systems?

Why choose our EWI solutions for your home

External Wall Insulation is one of the most effective ways to treat a cold house and solve issues with thermal bridging. By applying insulation boards to the exterior of your property, we create a thermal envelope that keeps heat inside during the winter and reduces your reliance on expensive heating systems. Our systems, featuring high-quality silicone or K Rend finishes, are perfect for a variety of builds, including traditional solid wall homes, non-traditional builds, and common structures like Wimpey no-fines houses. Beyond the energy savings, our render provides a clean, weather-resistant finish that protects your brickwork from the harsh Welsh elements.

How our PAS 2030 accredited team works

We take a professional, whole-house approach to every project in Ystradgynlais. As a PAS 2030 accredited and PAS 2035 compliant company, we ensure every stage of your retrofit is managed with precision. Our process begins with a detailed assessment of your property type and current energy profile. We then install the insulation system to current standards, followed by a professional render application. To ensure a truly seamless finish, our sister company, Global Plastering, is on hand to handle any internal finishing or traditional plastering required. This enables us to provide a comprehensive end-to-end service that leaves your property looking immaculate.

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.
