Product Description for PVC UPVC Profile
A casement window is hinged at the side and opens outward. It provides excellent ventilation,at times literally reaching out and catching the breeze. It looks like a narrow picture window because, unlike double hung or sliding windows, it has no rail to obstruct the view.
Some casement windows are simply pushed open, but most have a hand crank. Screens are placed on the inside of the window, where they're more protected from the elements. If you're installing windows over a sink, countertop or appliance, a casement window with a crank can be the perfect solution.
One of the things to look for in a casement window is how far it opens. The best open up perfectly perpendicular to the house for maximum ventilation
They are opened with a crank, lever, or cam handle, which is placed around hand height or at the bottom and serves as a window lock.
A crank, stay, or friction hinge is necessary when the window opens outward, to hold the window in position despite wind.
Often the glass panes are set in a rabbeted frame and sealed with beveled putty or glazing compound to secure the glass.
