Frequently Asked Questions
Energy Efficient Doors
Door‑Stop doors are designed to meet the latest UK Building Regulations, helping you stay compliant while delivering strong thermal performance. Current Part L standards require replacement doors in existing homes to achieve U‑values of 1.4 W/m²K or better, with even tighter targets for new builds depending on the specification.
Our composite doors are built to meet or exceed these requirements, giving you confidence on site and reassurance for your customers. With the right specification, including thermal glazing, even lower U‑values are achievable—helping improve energy efficiency, reduce heat loss and support more sustainable homes.
It’s all part of delivering doors that not only look right, but perform to modern standards.
