Window, Skylights & Glazing

Types of Windows

Double hung (sash windows)

These are one of the most common types of windows. They feature two sliding sashes that move independently of each other, in an up and down motion.
Classic in style, double-hung windows have an upper outside sash that slides down and a lower inside sash that slides up. Hidden springs, weights, or friction devices help lift, lower, and position the sash. With certain types, the sash can be removed, rotated, or tilted for cleaning. If only one sash slides, the window is called "vertical sliding" or "single-hung."

Horizontal Sliding

Sliding windows, as the name suggests, slide horizontally along a runner. They are suited to most architectural styles and are usually chosen for their versatility.
Only half of the total window may be opened for ventilation at a time.


Awning windows open horizontally outwards with a chain winde and tilted out towards the bottomr. These chains hold the window in place. They are often used in hard to reach spots, or when furniture obstructs access. A top-opening style, typically placed low on a wall, is called a hopper window

Louvre windows come in panels of slatted glazing that can be opened and closed in unison. They were used as a way to convert verandahs into sleep-outs and are common in beach homes everywhere.



Bi-fold windows, like bi-fold doors open either inwards or outwards, in a concertina fashion. Their purpose is to let in as much air and daylight in as possible.

Casement Windows


Casement windows open outwards to a 90-degree angle. A metal rod is used to hold the window in place. Hung singly or in pairs, casement windows are side-mounted on hinges and operated by cranks that swing the sash inward or, more commonly, outward. They open fully for easy cleaning and offer excellent ventilation because they can "scoop" in breezes.


Fixed pane

Fixed pane windows, as the name suggests, are fixed in place. They can not be opened.
