Two Minute Tips ... PICTURE Windows
Picture windows are fixed windows. They do not open for ventilation. They are used in combination with many of the other window styles. For example, it is common to have a picture window with a double hung window on each side of it. This is a classic look, and the picture window center is normally designed to be fifty percent of the opening, with each double hung window being twenty five percent. Since double hung windows each open about half way, this total window unit offers about twenty five percent ventilation.
If you desire more ventilation, you can pair up casement windows with a center picture window. Since casement windows open one hundred percent, your total window will now offer you fifty percent ventilation, twice as much airflow than if you used double hung.
A picture window installed above another window is called a transom. If you have an exceptionally tall opening, you may choose a double hung or a casement window with a transom above it. Small picture windows can also be used below another window. Think of a sunroom with a picture window below a sliding window. This opens up the sunroom to maximum light. All windows used installed closer to the floor than 18 inches are required to use tempered glass. Tempered glass is hardened using a heating process, so it becomes more resistant to accidental breakage. Other places where windows are required (by building codes) to be tempered are in bathrooms if near the tub, and within three feet of a door. Of course all door glass must be tempered today, including sliding and swinging patio doors, entry doors and even storm doors.
