7-1.3.2.1
Provide child activity rooms with glass exterior walls from a maximum sill
height of 280 mm (11 in.) above finished floor. Consider placing the sill bottom on the
finished floor for infant rooms. However, do not place sill heights between 75 and 255
mm (3 and 10 in.). Sills at those heights present falling hazards. Please note that the
ideal length to width ratio for the activity rooms is 3:2.
7-1.3.2.2
Consider providing up to 25 percent of the total number of windows as
operable, as long as children will not be able to operate them, or as long as no noxious
fumes from the building mechanical system or any other source are introduced into the
interior. Provide all operable windows with draft deflectors, screens, and safety locks,
and of a safety type to keep children from falling through. If operable windows are used
in the child activity rooms, install to be operable by staff only, opening at the top, rather
than accessible to children.
7-1.3.2.3
Locate or recess casement and other projecting types of windows or
awnings to preclude dangerous protrusions at child and adult heights at both the interior
and exterior.
7-1.3.2.4
For windows and doors with glass lower than 915 mm (36 in.) above the
finished floor, install safety guards or construct of safety-grade glass/polymer, and equip
with a vision strip. If cost permits, replace wire glass with an approved alternative.
7-1.3.2.5
Install window treatments in children's activity rooms that are resistant to
damage.
7-1.3.2.6
Use sills of durable material such as solid surfacing materials, plastic
laminate, etc. Ensure there are no sharp edges and that the sills project no more than
20 mm (.75 in.) from the wall.
7-1.3.2.7
If window seats are used, design to be between 250 and 300 mm (10 and
12 in.) above the finished floor and a minimum of 300 mm (12 in.) deep.
7-1.3.2.8
Use overhangs or tinted glass to prevent glare in children's activity rooms.
Avoid excessive or heavy tinting.
7-1.3.2.9
If required, provide horizontal blinds to eliminate direct exposure to the
sun. In the event blinds are used, equipp with child safety cords or enclose between the
panes.
7-1.3.2.10
Do not provide floor length draperies and vertical blinds in child activity
rooms.
7-1.3.2.11 Provide screens for windows used for ventilation. Locate screens in child
activity areas above child height.
7-1.3.2.12 If protruding 50 mm (2 in.) or more, do not locate horizontal window
muntins (horizontal mullions) between 300 mm and 1100 mm (12 in. to 43 in.) above the
finished floor because they could be used as climbing support.
