Excerpt from Increasing Efficiency and Decreasing Cost in School House Construction With Keystone Gypsum Blocks
In order to properly control the temperature of the school room, particularly in sudden mild weather, the heat should enter the room only at the points ih tended - the register openings. This efficiency has not been secured with either of these forms of con struction. The use of wood - stud - and-lath with metal lining offers nothing to oppose the transmission Of heat at any point of the flue from floor to ceiling, ex cept the plastering, which being composed principally of sand, possesses no value as an insulation. Further more, the life of the metal flue - lining is uncertain at best, involving the certainty of repairs in time, and always presenting the danger of fire from a defective or rusted joint.
While flues built of ordinary fireproof materials are superior to those of wood lined with metal, they are extremely heavy, and as nearly all of these mate rials are conductors rather than non-conductors of heat, fail to solve successfully the problem of prevent ing heat radiation.
