K Rend is a market-leading through-colour silicone render that offers a modern, durable, and low-maintenance aesthetic for any building type, from traditional Victorian terraces to modern residential builds. Unlike traditional sand and cement, this system is water-repellent yet breathable, which prevents the build-up of trapped moisture that often leads to internal damp and black mould. By choosing a silicone-based finish in Ystrad Mynach, you are investing in a long-term solution that maintains its colour and integrity for years to come, effectively acting as a protective skin for your property.

As PAS 2030 accredited specialists, we take compliance seriously. Every project we undertake in Caerphilly is managed with a focus on PAS 2035 whole-house retrofit standards, ensuring that our rendering work integrates perfectly with your insulation strategy. Whether you need thermal bridging solutions to stop heat escaping through cold spots or you are a landlord needing to improve your property's EPC rating to meet current MEES requirements, our technical approach ensures your home is warm, dry, and legally compliant.

One of the unique advantages of working with Global Energy Insulation is our ability to provide an end-to-end service.
