Have you ever wondered what casement window options were available?

According to wikopedia, The definition of a window is “… an opening in an otherwise solid, opaque surface through which light and air can pass. ” By definition, this includes the early windows which didn’t have any protection from the wind or rain. Early windows used shutters to protect the inside of the house from the elements. Modern windows may have be single, dual, or triple paned.

Casement Windows - Stylish, Secure, and Energy-Efficient

There are may different window styles, those more common today which are usually dictated by the weather conditions common to the area. Coastal climates, with stronger winds, tend to have smaller outward-opening windows while inland areas tend to have larger windows, with commonly open inwards.

* Replacement Windows: is a framed window designed to slip inside the original window frame from the inside after the old sashes are removed

* New Construction Windows: a window with a nailing fin designed to be inserted into a rough opening from the outside before applying siding and inside trim.

Common window styles are:

* Double-hung Sash Window: a Vertical style window with two parts (sashes) which overlap slightly and slide up and down inside the frame.

* Single-hung Sash Window: one sash is movable and the other fixed.

* Horizontal Sliding Sash Window: has two or more sashes that overlap slightly but slide horizontally within the frame. If there are 3 part, the center typically is a fixed panel.

* Casement Windows: An outward-opening window with either side-hung, top-hung, or combination of sash types. Often they have fixed panels on one or more sides of the sash. These are opened using a crank, by friction stays, or espagnolette locking.

* Tilt: a window which can open inwards at the top or can open hinged at the side.

* Jalousie Window: A window comprising many slats of glass that open and close like a Venetian blind usually using a crank.

* Skylight: A flat, sloped, or bubble window built into a roof structure for daylighting.

* Bay Windows: A multipanel window, with at three sections set at different angles to create an expanded area for shelving/sitting while allowing more light into the room that a flat window. The window creates a “seat board”, a small seating area or shelf often used for plants or items that would take up floor space. A bay window may be rectangular, polygonal or arc shaped. If arc-shaped it is a bow window.

* Bow Windows: a type of Bay window, but arc shaped with four or more glass sections to simulate a rounded appearance.

* Fixed: A window that cannot be opened. A non-opening window is sometimes called a “light” because its function is limited to allowing light to enter without any outside air.

* Picture Windows: A very large fixed window in a wall, which provides an unimpeded view “as if framing a picture”.

Classic windows styles:

* Clerestory: A fixed, vertical window set in a roof structure or high in a wall, used for daylighting. You’ll see these in the old churches around the world, like Notre Dame. Clerestory lights are any rows of windows above eye level for providing light.

* Oriel: Projects from the wall, and were originally a form of a porch. Often seen on upper stories of older buildings. Often supported by brackets, or by corbels (a type of architectural bracket), they do not reach the ground. These are the rounded columnar windows you see on older buildings.

* Palladian: A large arched window which is divided into three parts. The center section is larger than the two side sections. Renaissance and classical architecture often have Palladian windows.

Casement Windows and Double-Hung Windows: Which Is Better?

Casement windows are typically characterised by a window with one or more hinges, attached to a frame. Before the advent of sash windows, they were the most common type of windows used in households. Casements were once the most widely purchased style of windows, before sash windows became commonplace. They traditionally consisted of framed glass panes that were fixed in place by strips of lead and the window could be opened outwards.

Useful Properties

Whole Opening

Casements can be opened much further than any other type, since the entire window can be swung open. This can be compared to the following types of windows.

Double-hung style: the whole window cannot be opened only the upper or lower half can be open at any one time.



The large window opening can be dangerous at high levels, since the gap is typically sufficient for small person or child to crawl out of and therefore poses a risk for families with young children.

Incompatibility with Air Conditioning

Casements typically do not cater well for air-conditioning units since they open outwards, especially when compared to other types such as sliding windows.

Size Limitations

Casements are designed to open outwards which means the opening needs to be strong enough to support the window. This places limits on how large a casement can be without placing unnecessary strain on the window opening.

Characteristics Of Casement Windows

As long as one has a hole in his or her wall, there is potential for a window to take the spot. If the spot has long been occupied by one type of window, it may perhaps be time for a change as windows can do wonders for the internal and external. Replacement casement windows are generally quite easy on the installation as they come in an assortment of shapes and sizes. As its name suggest, it is the epitome of windows by allowing a generous amount of light and ventilation to traverse between both sides.

When choosing casement windows for replacement, the individual can opt for the hinged type affixed to the left, right or both sides of the frame. Depending on where the hinge is set, the window swings open to the left or right. Alternatively, some may prefer hinges to be fixed somewhere along the frame causing the casement to open out from the bottom and provide some shield from the rain. Degree of swing is generally dependent on the length of a metal arm attaching the casement to the frame. In the event one is hoping to allow maximum light and ventilation to pass through, it is best to inform the installer and check the work done. Otherwise, one may be left with a window opening at a shocker of 45 degrees or less. The more classic window may come with a metal arm perforated with holes at measured intervals allowing the home owner to select the swing degree and avoiding a slamming window due to strong winds.

Replacement casement windows also come in the sliding fashion, thus removing the concern with slamming windows. However, one is actually left with half a window space as window panes overlap when fully opened.

In considering casement windows for replacement, security can often be a cause for concern as the price to pay for better ventilation is greater exposure. To ward off any untoward incidents of the illegal kind, home owners may need to install security grills at the expense of the aesthetics. Bugs and pests can easily be kept out by putting up insect screens. Privacy issues are best addressed with blinds, shades or curtains. In warmer regions, some home owners apply adhesive film to bounce off heat and glare from the sun. There is however a pitfall to this act as it may darken the interior of the room by reducing the amount of light to pass through the treated glass.
