An Astragal On A Pair Fire Door?

- Jan 15, 2020-

An astragal is commonly used to hide the space between pair doors. The astragal closes the clearance gap created by bevels on one or both mating doors, and helps deaden sound. The vertical member (molding) attaches to a stile on one of a pair of either sliding or swinging doors, against which the other door seals when closed. Exterior astragals are kerfed for weatherstripping.


Asico Door offers T-Astragal at no additional charge with your order for double doors. Our T-Astragal moulding is 1/2" wide at the point where the doors meet. Or provide us with the overal opening width, and we will compute the door widths needed for use with T-Astragal. 


To install, attach T-Astragal to the edge of one door with the T-Astragal's decorative side facing the same direction as the swing. For example, if the doors are to swing outward, the decorative face of the T-Astragal must be on the outside also. 


Asico door's wooden fire rated door and hollow metal door can be with T-Astragal wooden or metal. This was also tested in the UL lab for pair door.
