Top 10 Window Styles
Deciding on a window for your home is about a balance between aesthetics and function; we get expert advice from Darryl Church on 10 basic styles.
Words by Darryl Church
Selecting a shape, position and material for your window is almost limitless. In most cases it is a balance between functional and aesthetic requirements. Large expanses of glass will open a room to the outside, but this may compromise privacy and allow excessive heat gain or heat loss. Too small a window, may not offer the desired amount of natural light, limit potential for any heat gain and prevent you from enjoying the external view. A general rule of thumb, is to allow more glazing to the north, and less on the south side of your house. But of course not all sites are orientated the same and the requirements for solar gain and views can be in completely different directions. A habitable space must have a window view to the outside, of which at least 50% is clear viewing. With energy efficiency awareness greater than ever double glazing is becoming a popular choice for most windows in the home. Generally the size limitation of a window is determined by the limits of glazing rather than the frame construction material so decide what kind of glazing you want first.
1. Bay Window
The Bay or Box window projects from the external wall. They are ideal for adding space to a room or above a kitchen bench. Their protrusion enables them to capture extra light and warmth. In this design by Dan O'Connor the Bay window allows for extra storage and a window seat to be created.
2. Double-Hung
With two glass panes moving up or down within the frame this style allows venting from top or bottom and is common in older homes, as seen above. Also known as a sash window.
3. Casement
Commonly found in newer homes, this style is hinged on the side and swings out like a door. A casement window can be single or multi-pane.
4. Louvered
Manually rotated to open or close this window can be opened by degrees to control how much air or light is allowed to pass through. As they are unable to be shut airtight they are typically used in smaller spaces, as drafts and security issues can arise.
5. Sliding
Available in single, double and multi-opening panels, sliding windows are often the safest option for decks and walkways.
6. Bi-fold
This style is the ultimate in indoor-outdoor living as it merges one area with another, as seen in this instance, the windows can be pushed back opening up the entire area of the window frame.
The most common frame choices in New Zealand are Aluminum, Timber, PVC, Steel and Composites, so there is window material choice no matter what the style of your home.
7. Sky Light
Perfect for adding extra natural light to the room there are many variations on this style of window to suit different roof pitches, elevations and needs. Some may open – operated by a long rod or electrically, while others may be there simply for extra light.
8. Picture
Also known as the fixed window, this is the simplest and most versatile element of window décor as it lets in the light but not the elements.
9. Geometric
Most commonly, this is seen with round-top windows, which can stand alone or be used as a crowning accessory to other windows, seen in this design. As this style will be custom made price can be a deciding factor.
Most window styles can be used in combinations to create a wall of glass that opens up to an outdoor space, or as an internal wall separating two living areas; you're only limited by your imagination and budget.
10. Awning
Designed to provide natural light and a breeze while maintaining privacy this window is placed high on the wall. Hinged at the top it will open on a horizontal angle.
