CHAPTER 9: INTERIOR FINISHES
Ceiling tiles should have high recycled content, which varies by manufacturer
and style. Ceiling tiles should be of a high (80% min) light reflectance to
enhance the lighting quality of the interior spaces. A limited area (2 m
squared maximum per classroom) of mirrored ceiling tiles are encouraged
over an activity area.
Painted gypsum board is appropriate in areas with soffits, ceiling height
changes, vaults, or wet areas. Do not use wall board for ceiling areas
where service access is required in the ceiling plenum for plumbing, HVAC,
or other equipment.
Exposing structural ceiling elements provides children an interesting
environment, and may increase the perceived height in low spaces, but
this can also require additional acoustical treatment such as the addition of
acoustical baffles.
A standard ceiling tile, easily replaced in case of damage, should be specified
for acoustic ceilings.
Luminous ceilings should not be used in areas occupied by children.
