High-Performance Thermal Construction

Designed as part of the Thermawood External Thermal Rated range, the Surrey delivers impressive insulation performance with approximate U-values of 1.32 – 1.36 W/m²K. Its advanced engineered construction helps reduce heat loss while providing excellent structural stability. The multi-layer construction includes:

• Structural LVL core with Meranti lipping for added strength
• Integrated 0.2mm aluminium sheet reinforcement for improved stability
• 3.6mm plywood outer layers for durability
• 45mm overall door thickness for a robust and reliable build

This innovative construction provides improved resistance to movement and warping compared with traditional timber stile and rail external doors.

Obscure Glazing for Privacy and Natural Light

The Surrey features a tall, narrow obscure glazed panel that allows daylight to enter your hallway while maintaining privacy. This makes it particularly suitable for entrance areas where you want a brighter space without compromising discretion. The glazing specification includes:

• Frosted / obscure toughened safety glass
• Low-E coating for improved thermal performance
• Argon gas filling for enhanced insulation
• Glazing tape and sealant system for long-term durability

The Thermawood Surrey is built to withstand demanding external conditions thanks to its reinforced aluminium layer and insulated core. The construction provides excellent stability and helps maintain performance over time. Key benefits include:

• Enhanced resistance to warping and movement
• Improved structural rigidity compared with standard timber doors
• Suitable for exposed installations in many applications
• 140mm frame width for additional strength and visual impact

Flexible Installation with 25mm Trimming Allowance
