Casement Windows Vs Sash Windows—Often Known As Double Hung Windows

One can finish aluminum frames with wood. Go to our main windows page to view Origin's casement window finishes.

Like aluminium, modern frames provide specialty glazing choices that use the benefits of current technology, therefore enhancing sound-proofing and thermal efficiency while preserving a classic look.
Casement Vs Awning (Top Hung Casement)
Many people refer to awning windows as top-hung windows. Though they are pivoted at the top instead of the side, they resemble traditional casement windows. Choosing between a side hung or top hung window requires consideration of various variables. A side-hinged window lets more quickly a breeze enter than an awning window. On the other hand, if the rain isn't severe, an awning window can be opened halfway to create ventilation without allowing water inside.
Usually, the decision between the two depends on the area you intend to fit the window in. While side-hung casements are usually selected for ground level living areas, awning windows are great in bedrooms.
Casement Windows Vs Sash Windows (Double Hung Windows)
Sash windows—also called double hung windows—may have less waterproofness than casement windows because of their opening style. Sliding one across the other in the limited area between the two panes makes it more vulnerable to drafts and damage from the elements. Over time, this problem can get worse since the opening mechanism might degrade the seals between the two panels, increasing the draughts' possibility.

The Parts of a Casement Window
Five basic elements define casement windows: sash, keepers, hinges, handle, and locking cam or handle.
Sash: A casement window's most important component since it is the element securing everything is sash. It especially helps the frame and the glass. It then moves sideways—inward or outward depending on the hinges.
Keeper: The locking handle and its hook in order to fasten the sash need a surface to adhere to. The keeper in casement windows performs this purpose. Usually it is found on the sliding panel's edge.
Hinges: Hinges are basically the element allowing the sash to swing or pivot. Usually for casement windows, the hinges are found on only one side. Most types of casement window hinges, though, are found at the top of the sash.
Handle: Linked to the sash, the operator handle allows the casement windows to open and close with rotation. Handles fall into two types: single and double.
Locking cam or handle: As suggested by its name, this device firmly locks the window sash in place. The style of casement window will determine whether you find one single locking cam or two handles. Typically depending on the circumstances, the locking cam is either in the middle or at the bottom of the casement window.

- The windows fall short in fit and do not close totally.
- Windows have drafts; no amount of weather stripping will completely address the issue.
