Window & Door Types

Every window and door is described by how it opens. If a term like tilt & turn, dual action, or lift & slide is unfamiliar, this is what each one means and where it is used.

Windows

Tilt & turn (dual action) window

A tilt-and-turn window, also called a dual-action window, does two jobs from a single handle. Turn the handle one way and the whole sash swings inward like a door for full ventilation, easy cleaning from inside, and a clear egress opening. Turn it the other way and the sash tilts inward at the top only, for secure background ventilation with the opening out of easy reach. All of the operating hardware is concealed inside the frame. It is the standard operable window across Europe, and it is the right choice wherever a window has to both ventilate securely and open wide.

Casement window

A casement window is hinged on one side and swings open like a door, usually outward. Because the entire sash opens, it ventilates fully and catches side breezes, and the harder the wind pushes on it, the tighter it seals against the frame. Casements give an uninterrupted view and a slim sightline.

Awning window

An awning window is hinged at the top and pushes outward from the bottom, so the open sash tips down and out like a small awning. That geometry sheds rain, which means an awning can stay open for ventilation during a light shower. Awning units work well set high on a wall, or stacked above fixed and operable windows.

Hopper window

A hopper window is the mirror image of an awning: hinged at the bottom and tilting inward at the top. Hoppers are common in basements and above doors, where they add ventilation in a short opening.

Fixed window

A fixed window does not open. With no sash movement or operating hardware, it delivers the slimmest sightlines and the largest possible area of glass, and it can be made in almost any shape, including arches, circles, triangles, and trapezoids. Fixed units are used wherever daylight and a view matter but ventilation is handled elsewhere.

Doors

Swing door

A swing door is hinged on one side and opens like a standard door, inward or outward. Multi-point locking draws the leaf tight to a continuous perimeter seal, and a low, accessible threshold keeps the transition flush. Swing doors suit entries, balconies, and terraces.

Sliding window & door

A sliding window or door runs one or more panels horizontally on a track, one gliding past the next. Because the panels stay in the plane of the wall, a slider opens a wide view and passage without sweeping into the room, which is ideal where floor space is tight. Configurations run from two panels up to multi-panel and pocketing runs that slide away into the wall.

Lift & slide door

A lift-and-slide door is the heavy-duty evolution of a slider. Turning the handle physically lifts the panels off their seals so even a large, heavy leaf glides with one hand; turning it back sets the panel down onto a continuous gasket and locks it in place. That lift-and-drop action gives far better air, water, and structural performance than an ordinary sliding door. Panels come in two-, three-, and four-leaf layouts, and the biggest units still open with one hand and close with a finger.

Bi-fold (folding) door

A bi-fold door, also called a folding or accordion door, is built from panels hinged together that fold and stack back against the jamb, opening a whole wall to the outside. Closed, the panels lock into a weathertight line. Folding walls can be built in almost any number of panels and configuration, so they suit patios, restaurants, and any opening meant to disappear entirely.

Not every type is offered in every system. See the product library for the openings available in the F-Series fiberglass and A-Series hurricane lines, or ask us for guidance on the right type for your project.
