MODERN DESIGN MEETS THERMAL EFFICIENCY
The Thermawood Grey Primed Berkshire is part of Doorphoria’s latest range of External Thermal Rated Doors, combining contemporary design with excellent energy performance. Designed to suit both modern and traditional homes, this 44mm thick door delivers impressive insulation with low U-values between 1.32–1.36 W/(m²·K) — helping to reduce heat loss and improve energy efficiency without compromising on style.
THERMAL RATED DOOR – ENGINEERED FOR THE BRITISH CLIMATE
The Berkshire is constructed with a grey primed marine plywood face, with a durable aluminium sheet positioned behind the outer layer to enhance stability and resistance to moisture. This layered construction provides excellent protection against the British climate while maintaining a traditional paintable timber appearance.
Unlike many standard timber doors, this design offers improved weather resistance and does not require a porch, canopy, or recess to maintain performance, making it a practical choice for exposed locations and busy households.
The door can also be trimmed by up to 25mm on all edges, offering valuable flexibility during installation — particularly for renovation projects and new-build properties.
STYLISH, READY-TO-PAINT FINISH
Supplied grey primed as standard, the Berkshire is ready to be finished in a colour of your choice. Whether you’re opting for a classic black, a bold contemporary tone, or a subtle neutral shade, the smooth primed surface ensures excellent paint adhesion and a long-lasting, high-quality finish.
SUSTAINABLE, CERTIFIED & GUARANTEED
Every Thermawood door is FSC certified, manufactured from responsibly sourced materials and tested to meet European building standards. With a lightweight construction, no stile or rail connection, and a 10-year manufacturer’s guarantee, the Berkshire offers long-term durability and peace of mind.
