Window types

Fixed windows offer uninterrupted views and strong thermal and acoustic performance when paired with the right glazing. Commonly used in façades, stairwells, and corridors, they support H1 compliance and can be combined with operable units for ventilation.

Top-hinged for upward opening, awning windows are ideal for controlled ventilation and weather protection. Often paired with fixed units, they’re a versatile choice for façades and elevations requiring airflow without compromising design lines.

Side-hinged for full opening, casement windows are well suited to tall or narrow configurations. Their vertical swing makes them a strong option for ventilation and natural light, especially where awning openings aren’t practical.

Sliding windows offer unobstructed openings and compact operation, making them ideal for tight spaces like walkways, balconies, and decks. Because the panels don’t project past the frame, they’re well suited to locations where safety or spatial clearance is a priority. 

For wider openings or greater indoor-outdoor connection, stacking windows allow multiple panels to slide behind one another—clearing up to two-thirds of the window span. This makes them a strong option for glazed façades or areas where increased ventilation and flow are key.

Bifold windows fold away to create a full-width opening, making them ideal for kitchens, cafés, or outdoor-facing spaces. Best used in areas where spatial flow and visibility are key.
