  • Filling material, window and door set, and filling method
    Patent number: 9523232
    Abstract: A filling material according to an embodiment of the invention includes: an outer cover material having elasticity; an expansion material being inserted into an inside of the outer cover material, wherein the expansion material being compressed when the inside of the outer cover material is evacuated; a nozzle being provided at one end of the outer cover material, wherein air is evacuated from the inside of the outer cover material or air is injected to the inside of the outer cover material to expand the outer cover material through the nozzle; and a stopper for blocking the nozzle in a state that the inside of the outer cover material is evacuated to maintain the inside of the outer cover material to be vacuous.
    Type: Grant
