Why Choose Global Energy Insulation for Insulated Render Systems?

How our insulated rendering process works

Our process begins with a thorough assessment of your property to ensure we select the right insulation and render system for your specific wall type. We install high-performance insulation boards directly onto the exterior, which are then reinforced with a breathable, weather-resistant base coat. The final stage involves applying a high-quality decorative finish such as silicone, monocouche, or K Rend. By choosing our service, you ensure that thermal bridging is eliminated, stopping cold patches from forming on your interior walls.

Why choose external wall insulation for your Powys home?

Installing insulated rendering is one of the most effective ways to lower your energy bills throughout the year. For many homes in Llanfair-Ym-Muallt / Builth Wells, including traditional solid wall properties and non-traditional builds like Wimpey no-fines houses, this process provides a critical thermal shield. Beyond the immediate comfort of a warmer home, our systems tackle damp and condensation issues at the source, preventing black mould growth. This improvement is essential for landlords aiming to meet current MEES compliance standards and improve the overall market value of their rental properties.

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.
