Do you need to know more about ceiling tile cost in a retrofit project? If you are building offices under an existing warehouse sprinkler system you will need to use melt away ceiling tiles from Universal Foam Products. Used instead of regular fiberboard ceiling tiles, they can be used when the sprinkler heads are above the office ceiling. In case of a fire, the EPS tiles will “melt away” allowing the sprinkler heads to operate. An effective solution to a common commercial retrofit.
