This Silicone Render in Chelmsford project involved a complete aesthetic refresh of a property using a premium sandstone silicone render. The goal was to replace the aged exterior with a crisp, modern finish while providing a durable weather shield.
Render Only vs. External Wall Insulation (EWI)
It is a common misconception that a new coat of render is the same as insulation. While this project delivered a stunning visual result, it was a “Render Only” application.
Aesthetic & Protection: The Sand Stone finish provides an immediate “new-build” look and protects the masonry from the UK’s harsh driving rain and frost.
The Thermal Reality: Unlike a full EWI system, render only does not include an insulation layer. While the walls look beautiful, heat still escapes through the original structure.
The EWI Specialist Advice
To achieve maximum efficiency, we always recommend combining a decorative render with External Wall Insulation. By adding a high-performance “thermal jacket” beneath the render, you not only transform the look of your home but also slash energy bills and hit the mandatory 0.18 W/m²K U-value targets required by 2026 standards.
