Types of Windows and Treatments

Types of Windows and Window Treatments to Suit

Sliding Glass Windows or Picture Windows

Definition: Aluminum framed glazed sliding window in Aluminum frames with picture window to the side where it slides back into. It is used as a door to access patio/terraces etc.

Possible Treatments: Sheers & Nets. If privacy is required these can be used, but they would have to be on an easily drawn track so that when the door is required they can be drawn with ease, although they are not really recommended as when the door is open they blow out the window to envelope you!

Curtains. A track above the window and door allowing for overhang at door side (or both for symmetrical look), so that the curtain can sit off the door handle. Floor length curtains are required as the door and window base are at floor level. Lining is important, unless double-glazing is used, for insulation purposes with these large windows.

Blinds. Most forms can be used, probably best to use two separate blinds so that you can raise one to use the door and still have one blind down to cover the window. Most blinds can be used, take into consideration the other window treatments in the room.

Shutters. These can be used if there is space for them to slide back or bifold back.

Dormer Window

Definition: A vertical window through a sloping roof, usually provided with it’s own pitched roof, creates an alcove type extension to the room.

Possible Treatments: if it has solid sides, same as a casement window. If it has glazed sides, leave it as is or fit track or blind fittings inside window frame for sheers or curtains.

Bay Windows

Definition: Three or more windows set at an angle to each other projecting out from the building creating a recessed area.

Note: It is important when planning decoration for these windows to consider the bay as one unit.

Possible Window Treatments:

Nets & Sheers. Use a slim track to follow the line of the windows. If curtains are also required a double track can be mounted.

Curtains. Floor length curtains on a track, which follows the line of the windows. They should be drawn back to each side, not cut up and bunched at ends of each window. Floor length curtains can also be used straight across the opening, which cuts off the space when drawn. The track can be ceiling mounted or fixed to a bulkhead if available. Some Bay windows are an ideal location for window seats; in this scenario sill length curtains can be use so that they don’t interfere with the seat. These can also be used in homes that have radiators or night store heaters under the windows.

Blinds. These can be a very effective option with the chance to use your imagination. Use one blind per window ensuring that they don’t overlap and catch when being raised and lowered. All types of blinds can be used.
