Projecting Sash Window

Commercial Series

Projecting Sash Windows provide a revolutionary method of delivering ventilation and unobstructed views with a sash that slides forward, parallel to the outer frame.

Projecting Sash Windows are endlessly customisable, offering stunning architectural designs and outstanding features.

Rylock Commercial Series Projecting Sash Windows offer ventilation through an unobstructed view with no flyscreen. The product is fitted with two multi-point handle latches (available in black, silver and white) that are rotated 90 degrees to unlock the sash with a range of motion that is controlled by four stainless steel stays. This allows the sash to slide forward by 125mm for a narrow perimeter of ventilation.

Dual sash seals fitted to the sash and frame ensure resistance against air and water infiltration for exceptional results in AS 2047 Windows and External Glazed Doors compliance testing. Projecting Sash Windows are glazed in accordance with AS 1288 Glass in Buildings and whilst a large range of options are available, all products are glazed with Grade A Safety Toughened Low-e Double Glazing (Argon Fill) as a standard specification.
