Hyline 40 Sliding Doors

Hyline 40 Sliding Doors

The world’s slimmest sliding door system

The Hyline HY40 ultra slim sliding doors provide users with a stylish design, superior sound & thermal insulation, as well as customisable options for increased practicality. The durable frame is designed to support large window sizes up to 6m in height & 28m2 in surface area with a double-glazing thickness of up to 38mm. This system stands apart due to its slim centrally located mullion which creates outrageously slim sightlines & a seamless experience between indoors & outdoors while the floor option conceals the frame allowing for an uninterrupted threshold. This robust system is ideal for any high-end building where a sleek, luxurious design is essential – one unique factor is the ability to tile the track creating a flush & sleek threshold.   Hyline offers unique & mouldable products, designed to meet the varying needs of architecture & otherwise impossible glass panel sizes. Taking advantage of the latest technology in aluminium window framing systems, it offers users the potential to improve the style and function of their space with floor-to-ceiling glazing. Furthermore, Hyline delivers additional convenience with motorisation, low-profile sides & vertical frames creating wide views with an impressive 18mm sight line. With such features that bring a commitment to achieve quality as well as perfection in design, Hyline provides countless tailored opportunities for innovation & appearance.


Hyline is changing the face of glazing systems globally by providing industry-leading slim-profile sliding doors & window assemblies.
