Thermally Efficient Clear-Glazed External Door
The Thermawood Grey Primed Dorset brings light, warmth, and efficiency together in one elegant design. Part of Doorphoria’s new External Thermal Rated Door Range, it offers U-values between 1.32 and 1.36 W/(m²·K) to help maintain indoor comfort and reduce energy costs — perfect for modern and traditional homes alike.
Engineered for British Weather
Built with a unique aluminium sheet facing, the Dorset provides exceptional protection against rain, moisture, and temperature change. You don’t need a porch or canopy — the durable construction keeps the door stable and weather-resistant in exposed conditions.
Its clear glazed panel allows natural daylight to brighten your hallway or entrance while keeping a contemporary look that complements any façade. Each 44 mm-thick door can be trimmed by 25 mm on all edges, making it a versatile choice for both new builds and renovations.
Grey Primed and Ready for Finishing
Supplied grey primed (RAL 7038) with an Anker Stuy Hydrolux Duocoat water-based primer, the Dorset is moisture-regulated and ready for painting. Apply your chosen top-coat colour for a personalised finish that protects and enhances the door’s modern appeal.
Quality Assured and Certified
All Thermawood doors are FSC Certified and tested to European standards for sustainability and performance. Each one includes a 10-year manufacturer’s guarantee and is lightweight for easier installation — no stile or rail connection required.
🧰 Care & Maintenance
Before fitting, inspect and acclimatise the door for 24–48 hours in a dry, ventilated space.
Seal and finish all 6 sides before hanging, trim equally from both sides (max 25 mm per edge), and reseal all exposed edges.
Clean every two years with mild detergent and re-coat if paint shows signs of cracking or fading.
