Engineered Construction for Strength & Stability
Unlike traditional solid timber doors, the Derby Chameleon uses engineered construction. This improves stability, reduces movement and increases durability in changing weather conditions.
The solid mixed timber core delivers excellent strength while the oak veneer provides a beautiful natural finish.
To maintain warranty cover, we recommend fitting an oak weather bar and finishing the door with a high build wood stain.
Water-based finishes should not be used.
