The Thermawood Grey Primed Rutland External Door is a high-performance, thermally rated external door that blends traditional styling with advanced insulated construction. Featuring two vertically proportioned clear glazed panels above raised lower panels, the Rutland delivers classic kerb appeal while meeting modern energy efficiency standards.

Supplied grey primed (RAL 7038) as standard, this door is ready for final decoration, making it ideal for both renovation and new-build projects.

The Thermawood Rutland is engineered to provide strong insulation and structural stability. Achieving impressive U-values of approximately 1.32 – 1.36 W/m²K, this door helps reduce heat loss and improve overall energy efficiency.

• XPS insulated core
• Structural LVL core with Meranti lipping
• Integrated 0.2mm aluminium sheet reinforcement for added strength
• 3.6mm plywood outer layers
• 45mm overall door thickness

The Rutland features two clear glazed units designed to maximise natural light while maintaining insulation performance.

The glazing specification includes:

• Clear toughened safety glass
• Low-E coating with Argon gas filling for improved thermal efficiency
• Installed using glazing tape and sealant system for durability
• This ensures excellent performance in exposed external environments.

Thanks to the integrated aluminium sheet layer and insulated core, the Thermawood Rutland offers:

• Enhanced resistance to warping and movement
• Improved structural rigidity
• Suitable for exposed locations without requiring a porch or canopy in many installations
• This makes it a practical solution for front and rear external door applications. 

The Rutland combines vertical glazed panels with raised lower panels and subtle V-groove detailing, offering a timeless look that works across both traditional and transitional properties.
