K Rend is widely recognised for its superior performance compared to traditional sand and cement renders. As a through-coloured system, it eliminates the need for regular painting, saving you time and money on maintenance. In the challenging Welsh climate, this silicone-based solution provides excellent water resistance, which is vital for preventing damp and cold wall issues. By choosing our expert team, you also benefit from thermal improvements that help stabilise your indoor temperature throughout the year.

We take pride in our status as PAS 2030 compliant contractors. When you choose us for your project in Treherbert, you are guaranteed a process that meets the highest national standards. Our team handles every aspect, from initial site surveys to full PAS 2035 retrofit coordination. We ensure that our rendering work works in harmony with your home's structure, effectively tackling thermal bridging and helping you achieve a better EPC rating, which is essential for meeting current landlord MEES compliance standards.

We believe in offering a seamless end-to-end service for our clients. While Global Energy Insulation focuses on the external thermal envelope and rendering, our sister company, Global Plastering, manages all internal finishes to a professional standard. This unique partnership ensures that your renovation project is managed by one cohesive team, whether you are refreshing a single wall or undertaking a full-scale property retrofit across South Wales and the South West.

We back our external rendering work with SWIGA (Solid Wall Insulation Guarantee Agency) support, providing you with an insurance-backed guarantee for total peace of mind. We hold a valid waste carriers licence and maintain comprehensive public liability insurance, ensuring your project is handled safely and responsibly. From the initial consultation to the final finish, we treat your property with the care it deserves, ensuring every detail meets local building regulations.
