The Slimmest Sliding Door System in the UK

The Landscape is Changing in Aluminium Sliding Doors



We have recently launched the AP Infinium Sliding Door system which is causing a sensation in the aluminium window and door industry. Read what Homebuilding and Renovating Magazine had to say in their May edition.


Alpine Aluminium has launched the UK’s slimmest aluminium sliding door to create maximum viewing space and enhance aesthetics for homeowners.


With a sight line of just 21mm, Alpine’s AP Infinium system can support expansive glazed panels up to 3m in width and 3.5m high. The ultra-slim product also offers an exceptional thermal performance with the triple glazed option achieving a u-value of less than 1.0, which exceeds Passivhaus requirements.



Josh Parkin, General Manager at Alpine Aluminium said: “As a UK manufacturer with a specialist facility, we are focused on continuous product development and innovation.


“The AP Infinium has been designed to create a wow factor for homeowners, offering a very contemporary appearance that maximises the viewing area and natural light. The product has the added benefit of improving thermal and energy efficiency delivering very low u-values.”

The AP Infinium adds to Alpine’s vast range of bespoke products including aluminium doors, windows and roof systems available in a wide choice of styles, which are installed to the highest standards.

All of the company’s products can be delivered within short timeframes – often as little as five days. Homeowners can also take advantage of Alpine’s full-service package which comprises an initial site survey, manufacture and installation backed by lengthy and comprehensive guarantees. Based in Leeds, Alpine Aluminium works with customers across the UK offering a fully fitted or supply only service.
