The Mendes Thermawood Berkshire Grey Primed external door is a high-performance solution that combines contemporary styling with outstanding thermal efficiency. Designed for modern homes, renovation projects, and new-build developments, this external door offers excellent insulation, exceptional durability, and a sleek horizontal groove design that enhances any property's exterior.
Supplied grey primed in RAL 7038 as standard, the Berkshire is ready for its final topcoat, allowing you to customise the finish to suit your home's exterior colour scheme. The primed surface provides an ideal base for painting while reducing preparation time during installation.
Outstanding Thermal Performance
The Thermawood Berkshire has been engineered to deliver impressive thermal efficiency, achieving U-values of approximately 1.321.36 W/m²K. Its advanced insulated construction helps reduce heat loss, improve energy efficiency, and contribute to a more comfortable indoor environment throughout the year.
Its innovative multi-layer construction includes an XPS foam insulation core, a structural LVL core with Meranti lippings, plywood outer layers, and an integrated 0.2mm aluminium reinforcement sheet. Together, these components create a robust, stable external door with a 45mm overall thickness, offering significantly greater strength and insulation than many traditional stile-and-rail doors.
Built to Withstand the Elements
Designed for long-term external performance, the Thermawood Berkshire is engineered to cope with changing weather conditions. The insulated core and internal aluminium layer improve resistance to movement, twisting, and warping, helping the door retain its appearance and performance over time. In many installations, the door can also be fitted without requiring a porch, canopy, or recessed entrance, making it a practical choice for both front and rear entrances.
Modern Horizontal Design
The Berkshire features clean horizontal U-groove detailing on both faces of the door, creating a refined contemporary appearance that suits modern architecture while remaining versatile enough for renovation projects. The subtle grey primer provides a neutral finish that can easily be painted to complement virtually any exterior style.
Flexible Installation
One of the standout advantages of the Mendes Thermawood Berkshire Grey Primed is its generous trimming allowance. The door can be trimmed by up to 25mm from all edges, making it an excellent choice for renovation projects, replacement doors, non-standard openings, and installations where on-site adjustments are required.
The Mendes Thermawood Berkshire Grey Primed is available in 1981 x 838 x 44mm and 2032 x 813 x 44mm, providing options to suit a variety of standard external door openings.
