Double Hollow Metal Doors Brush Seals
Door Seals and Weatherstripping for Double Hollow Metal Doors
When both sides of a double metal door or double hollow metal door will be used, two strip brush door seals are needed on the center line. If one side of the hollow metal doors is locked down and unopenable, only one side need be sealed in the center. With all four sides sealed with a Memtech brush door seal or weatherstripping, the double metal door is virtually airtight.
