Windows come in many styles, shapes and sizes. When looking for a replacement window you can often use the opportunity to fit in a completely new type to the one you had before. Detailed below are the various window styles you will find on the market with a description of each.


Awning windows open from the bottom and are common instalments in the upper levels of a home, including the roof. They are perfect choice for letting in large amounts of ventilation and light. These types come in all sizes from the very large to the very small depending on the location desired.


Bay windows protrude out from the plane of the wall. This allows a room to be transformed both physically and in the amount of light that is allowed in to the interior. In many cases, the side windows can be opened to allow increased ventilation. These types are mostly used for kitchens and living rooms but can be applicable for almost any room in the home.


Casement windows are probably one of the most common types you’ll find. They open outwards horizontally. Their ease of use and manoeuvrability means they can be placed in hard to reach places such as above sinks and large appliances in the kitchen.


Double-Hung windows are two panes placed one above the other. They are opened by sliding either window, up and down. These types are very common in old houses and in many cases are much admired for their old-world charm. Great for ventilation, they are ideal choices for the home office or bedroom.


Fixed windows are basically those that cannot open and are designed to stay in place without any movement. These are common on the side of houses where windows overlook an inner staircase. Small glass panels above larger windows or doors are also fixed.


Hopper windows open vertically from the bottom with the opening at the top. They also open inwards rather than outwards. These are mostly used in basements because they are a good barrier, when open, against the dust, leaves and water spray found at low levels. The compression seal most types of Hopper windows have means they are also highly energy efficient.

Jalousie windows are comprised of a series of slats, or louvers, that overlap one another. They can be manually open and closed to varying degrees to allow extra or decreased ventilation. These types of windows are more popular in warmer climates. Unfortunately, in most cases, the seals are not air tight and so are not advisable for use in more northern areas of the country.


Oriel windows are similar to bay windows but are usually found on upper levels of a building. Unlike bays, the protrusion outwards does not reach all the way to the ground. They are supported by brackets or cantilevers and are mostly small in nature.


Palladian windows are named after the Renaissance architect Andrea Palladio. These are comprised of three windows where two smaller ones sit either side of a larger one which is almost always arched. Most ordinary residential Palladians use the double-hung type of window.


Rotating windows are the most versatile type of structure you can find. They open from either side as well as from the top or the bottom. Their center pivot means they are ideal windows for adjusting light and ventilation in an interior, plus are very easy to clean if located on an upper level.


Single-Hung windows are identical to the Double-Hung except for the fact that the upper of the two windows is fixed and cannot move.

Sliding windows are panes that move sideways along grooves or tracks when opened and closed. These are particularly useful when large windows are desired and allow in a lot of light.


Windowscape windows are the largest of the lot and are basically entire walls made from glass. These are popular for holiday homes, beach huts, condos and sunrooms.
