Excerpt from Hospital World, Vol. 7
Since the practice of fireproofing these opening is so general in commercial buildings, why use anything else in hospital work? There are many American concerns ready to make any required type of fireproof door or window at a cost attractive to commercial interests.
The use of metal frames about doors is common practice at present. The best type of metal door frame is probably one made in Germany, a solid steel rolled section with invisible hinges, throwing the door clear of the opening. Many good types of heavy sheet steel frames are now on the market. The use of metal frames for doors and windows gives a permanent and perfect joint with the wall finish, and, being non-shrinkable, no cracks develop. The absolute adjustment of moving parts possible, and the freedom from shrinking and swelling, render the operation independent of the seasons. Solid and perfectly plain doors can be obtained in metal. These can be decorated with enamel or grained to any wood as desired, giving a similar finish to that seen in Pullman coaches. The use of metal for window frames leaves a larger glass and air area in a given masonry opening than can he accomplished with the ordinary wood finish.
A later type of window is made in three sashes, with the lower stationary as a wind break, and the upper two sliding past each other and operated by a ratchet, which does away with the weights.
