FIRE-RESISTANT GLAZING DESIGN FOR GLASS ROOFS Russian patent published in 2018 - IPC E06B3/66 E06B5/16 H05B3/84 

FIELD: construction.

SUBSTANCE: present invention relates to the field of building materials and products, namely to fire-resistant glazing structures for glass roofs, and is intended for use as a fireproof barrier to the spread of fire in a fire through the glazing of glass roofs, skylights, lantern lights. Technical result is achieved due to the fact that in a fire-resistant glazing design containing external and internal glass, installed and fixed at a certain distance from each other, these outer and inner glasses are multilayer, consisting of tempered glasses, bonded to each other by adhesive layers, and on the inner surface of each glass layer of the inner laminated glass there is a selective heat-reflecting coating arranged to reflect the thermal radiation from the surface of the second laminated glass sheet inside the room.

EFFECT: technical result of the invention is to increase the strength of the structure while ensuring its high fire resistance rating.
