What Is Silicone Render and Is It Worth It in the UK? | HouseRenderPro

What Is Silicone Render?

Silicone render is a modern, polymer-based external wall coating containing silicone resins. Unlike traditional cement renders, it’s:

• Flexible: Moves with building settlement (up to 5mm)

• Breathable: Lets moisture escape (vital for UK damp)

• Hydrophobic: Repels rain like a "self-cleaning umbrella"

• Pre-mixed: Available in 200+ ready-mixed colours

Developed for Europe’s wet climates, it’s become the #1 choice for UK new builds and renovations (NHBC 2025 data).
