When considering guarding to french windows a mini mum guard height of 1100mm measured from finished floor level is required to ensure adequate protection from falling.
Window height from floor level.
Height of window from the floor can be calculated by following calculations.
Therefore glazing that protects people from falling must meet these requirements fixed low level glazing where the design incorporates low level glazing less than 800mm above internal floor level such as a window that is fixed not openable glazing and the framing will need to function as guarding where the difference in floor levels exceeds 600mm.
The standard height of the window from the floor level is generally kept 900mm or 3 ft.
Standard window height in homes with eight foot ceilings most windows are 48 high although may be as short as 42.
Height of window from floor level height of door height of window.
It can vary depending upon the size of the window ceiling height and owner requirement.
If the height of the door is 7 ft and the height of the window is 4 ft then the height of the window will be 7 ft 4 ft 3 ft.
This figure is almost consistent with the guidance given in bs8213 1 which recommends 1120mm high guarding for french windows when sited above ground floor level.
Homes with nine foot ceilings may have windows from about 48 to 60.
If you are installing windows within 2 feet of a door and lower than 5 feet from the ground you need tempered glass in the windows even though these might be higher than 18 inches from the ground.
Diagram 1 when considering guarding to french windows a minimum guard height of 1100mm measured from finished floor level is required to ensure adequate protection from falling.
The standard height of window from floor level is 900 mm or 3 ft.
Depending on what you re looking to accomplish your budget and the construction of your home your new windows may be able to be taller.
Where an upstand is formed up to 300mm high to the base of the opening then an 800mm guard height should be maintained above this level.
To lean over an obstruction that is 600mm 24in deep and 900mm 35 in high such as kitchen base units the window control must be no higher than 1 7m 5ft 7in above floor level.
