Opening Possibilities

1. Casement Window

Our casement windows are available as a fixed/picture window or push-out / in-swinging window. They can be designed with single or double sashes.

The main benefit of installing casement windows is their flexibility. They can open up to 90° internally or externally offering unlimited ventilation.

Opening Possibilities

2. Hopper

Hopper windows are an excellent solution for efficient ventilation. Hinged at the bottom of the frame, tilting inwards, they leave a small opening at the top of the frame. Hopper windows are often found on multi-level or high-rise buildings

as they provide both ventilation, and high fall protection. Easily integrated with our casement window systems, hopper windows can also be installed over doors for added ventilation and to increase natural light.

Opening Possibilities

3. Tilt & Turn Window

The tilt and turn mechanism allows the user to open the window in two ways. Turning the handle 90°, the window will tilt inwards at the top like a hopper.
At 180°, the window will swing inwards, opening fully like a casement window.

Tilt and Turn windows are the perfect solution for trickle or purge ventilation and for hard-to-reach areas that require ease of access for cleaning or maintenance.

Opening Possibilities

4. Awning

Awning windows are hinged at the top of the frame and swing outward from the bottom. They are the perfect solution to ventilate the room, even in rainy weather.

Like our hopper windows, awning windows can be easily integrated with our casement windows or door systems to improve ventilation and increase natural light.

Opening Possibilities

5. Parallel Sash

The Parallel Sash consists of an operable sash with scissor hinges, that moves outward in a horizontal direction, perpendicular to the frame. It provides efficient natural ventilation to the building, achieving approximately twice the natural ventilation of equivalent sized awning windows.

Offering a streamlined aesthetically pleasing finish, the parallel sash does not take up any room on the inside of the building and finishes flush to the external wall or facade. The parallel sash is usually integrated with our curtain wall system offering a modern ventilation solution. .
