Fire-proof window |
摘要 |
This invention relates to a highly effective fire-proof window consisting of at least one glass sheet mounted in a frame, the frame being such that when the glass sheet is exposed to the effect of heat in a fire, it will be subjected to a somewhat uniform heat effect thus preventing breakage due to the buildup of stresses. Uniform heating is produced by the inclusion of a covering along the edge of the glass which falls away upon heating of the window.
