Mendes Thermawood Devon (Osbcure Glass) Grey Primed Door

Mendes Thermawood Devon Obscure Glass Grey Primed External Door

This product can be considered alongside our external doors collection and wider selection of exterior doors for a coordinated entrance. The Mendes Thermawood Devon Grey Primed External Door combines traditional entrance door styling with advanced insulated construction, creating a high-performance solution for modern homes. Featuring an elegant arched panel design with a centrally positioned obscure glazed unit, the Devon offers the perfect balance of natural light, privacy and thermal efficiency. Supplied grey primed in RAL 7038 as standard, this external door is ready for a final topcoat finish, allowing you to customise the appearance to complement your exterior colour scheme.

Thermally Efficient Insulated Construction

Designed for improved energy performance, the Thermawood Devon delivers excellent thermal efficiency with approximate U-values ranging from 1.32 to 1.36 W/m²K. Its advanced engineered construction helps reduce heat loss while providing greater stability and durability compared with traditional timber external doors. The multi-layer construction includes:

• XPS foam insulated core for improved thermal performance
• Structural LVL core with Meranti lipping for added strength
• Reinforced 0.2mm aluminium sheet layer within the door structure
• 3.6mm plywood outer layers for enhanced stability
• 45mm overall door thickness

This robust construction helps improve resistance to movement, warping and changing weather conditions, making the Devon suitable for exposed external installations.

Obscure Glazing for Light and Privacy

The Devon features a central obscure glazed panel that allows natural daylight into your hallway or entrance area while maintaining privacy. The glazing combines style with performance, making it ideal for homes where both brightness and security are important. The glazing specification includes:

• Frosted / obscure glass for privacy
• Toughened safety glass for added durability
• Low-E coating with Argon gas filling for improved insulation
• Glazing sealant and tape system for long-lasting performance

Durable Design for External Conditions

Built with a reinforced insulated core and aluminium strengthening layer, the Thermawood Devon is designed to provide excellent stability in demanding environments. Its engineered construction helps minimise the risk of movement and provides a reliable alternative to traditional timber doors. The door is suitable for a wide range of applications, including:

• Front entrances and replacement door projects
• Modern homes and new builds
• Renovation projects and older properties
• Properties requiring improved thermal performance

Flexible Installation with Generous Trimming Allowance

The Thermawood Devon offers excellent installation flexibility, with the ability to trim up to 25mm from all edges. This makes it particularly useful for replacement projects, renovation work and installations where opening sizes may require adjustment.

Traditional Styling with a Contemporary Finish

The Devon design combines a classic arched panel layout with modern vertical groove detailing, creating an attractive entrance door suitable for both traditional and contemporary properties. The grey primed RAL 7038 finish provides a smooth base ready for final decoration, allowing you to choose a colour that complements your home's exterior.
