The slimmest aluminium sliding door
system available in the UK
Manufactured and hand finished at our specialist factory and available to view at our showroom in Leeds, Alpine’s AP Infinium slimline aluminium sliding door system is not only the slimmest available in the UK, but able to support panels of up to 3m in width and 3.5m high and available as either a double or triple track. With a U-value of less than 1 (on our triple glazed option), the AP Infinium satisfies even the most stringent PassivHaus requirements in thermal efficiency.
However, it is aesthetics that ensure the AP Infinium stands out from the crowd – the outer frame is fully concealed and with a central interlock of just 21mm, the Sliding Doors provide a virtually uninterrupted view of the outside landscape from the comfort of your home. In addition, a floating corner post is available, creating an even larger opening space. Accompanied by lengthy guarantees, incredible air and water tightness, and security robustness, the AP Infinium is truly the leader in Aluminium Sliding Doors looks and performance on the market today.
