Designed to emulate the industrial aesthetic of traditional steel, these doors utilise the robustness of aluminium, a contemporary material known for its strength and durability. Notably, these doors don’t merely meet aesthetic and practical requirements, but also comply with the ‘Document L Building Regulations’. This guarantees their thermal performance, making them a sound choice for energy-conscious homeowners.
