Aluclad lift and slide doors are designed for projects where aesthetic appeal and thermal performance are equally important. The timber interior offers timeless elegance and a warm, natural finish, while the aluminium exterior requires minimal maintenance and stands up to the UK climate over the long term.
This is the perfect solution for luxury homes, architect-designed self-builds, and modern architectural projects where large glass surface areas, smooth operation, and premium detailing are central to the brief. The lift and slide mechanism raises the entire sash onto precision rollers, allowing even the heaviest panels to move with effortless ease.
Every set of Aluclad lift and slide doors we manufacture is built to order, responding to the individual requirements of the project. Colour options span the full RAL classic range, with dual-colour finishes available – a different tone inside and out – to suit both interior design preferences and external architectural palettes.
With triple glazing as standard, multipoint locking, and double gasket sealing for weather tightness, these doors are a reliable performance choice for clients and specifiers who won’t compromise on quality. For further information on specifications or to discuss your project, our technical team is available to help at every stage.
