Why Choose Global Energy Insulation for Insulated Render Systems?

Why choose external wall insulation for your Monmouthshire home?

Many properties in the Trefynwy area, particularly traditional solid wall buildings, suffer from significant thermal bridging and damp issues. Our external wall insulation systems provide a robust shield that keeps heat inside during winter and maintains a comfortable temperature year-round. By installing these systems, you can significantly improve your property's EPC rating, which is essential for landlords meeting current MEES requirements and homeowners looking to increase the long-term value of their investment.

What is the process for installing insulated render systems?

Our process begins with a professional assessment to ensure your property is suitable for external wall insulation. As PAS 2035 compliant specialists, we follow strict industry guidelines to ensure the installation is safe, effective, and compliant with all local building regulations. We install the insulation boards directly to the exterior, followed by a durable, weather-resistant render finish. This method ensures a seamless, aesthetic transformation that protects your brickwork from the elements while preventing the common issue of black mould and condensation.

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.
