Appendix I 1.4 CEILINGS

I.4 CEILINGS

Ceiling finishes that reduce or omits the use of toxic chemicals, VOCs, and pollutant emissions are preferred.

I.4.1 GYPSUM

See charts in the Interior portion of Section 8 for locations and instances where gypsum board is an acceptable ceiling. Gypsum ceilings can be used as accent soffits and as bulk heads to break up suspended acoustical tile ceilings. Coved or special ceiling details can be created for spaces such as conference rooms. Gypsum ceilings should also be provided in areas where cleanliness is an issue, such as restrooms. The finish texture is to be smooth and all ceilings are to be painted with a minimum MPI gloss level 3. Ceiling color is to be a ‘ceiling white’ which provides maximum light reflection.

I.4.2 SUSPENDED ACOUSTICAL TILE

See charts in the Interior portion of Section 8 for locations and instances where suspended acoustical tile is an acceptable ceiling. Acoustical tile is to be the primary ceiling material for most facilities. The tile is set in a suspended grid system. This type of system provides easy access to the space above the ceiling. Provide 5% minimum overstock for future modifications.
