Curriseal is an integrally gasketed, one piece hollow metal door frame. Gaskets installed in the integral kerf significantly reduce air flow between the door and frame. Assemblies can be fire rated up to 3 hours and have been tested by ANSI/NFPA 105, UL 1784, ASTM E-283, and UBC 3305 or UBC 1004.3.4.3.2.1 Test Criteria.
Specifications
Curriseal frames shall be manufactured by CURRIES of Mason City, Iowa. Frames shall have a 1/8" (3) integral kerf formed into the frame soffit to receive a gasket composed of a cellular modified foam core clad in an embossed, non-vinyl, paint-resistant liner which is UV stabilized. Frames comply with NFPA 105 Smoke and Draft Control Door Assemblies, UL 1784 Air Leakage Test of Door Assemblies, ASTM E-283 Air Infiltration, and UBC 3305 Air Leakage Test of Door Assemblies; they can be UL listed fire door frames up to and including 3 hour ratings. Frames are to be fabricated of either cold-rolled steel or galvanneal steel (as specified) of either 18, 16, or 14 gauge. Joints are to be die-mitered with integral tabs for reinforcement and inter-locking of the jambs to the head. Frames shall be knock-down or set-up and welded (joints are to be full saw mitered or saw butt end on high speed metal cutting saw and full welded).
Welded frame corners shall be finished to a smooth surface. Frames shall be thoroughly degreased, cleaned, and phosphatized prior to painting. Frames shall receive a factory baked-on coat of rust inhibitive primer. Frames are to be mortised, reinforced, and drilled and tapped for mortise hardware compatible with the kerf frame profile. Frames are to be reinforced only for surface mounted hardware, with drilling and tapping to be done in the field by others. Metal plaster guards are provided for all mortise cutouts. Minimum requirements for hardware reinforcements are as follows: Hinge Reinforcing — 7 gauge x 1 5/8" (41) x 10" (254), Lock Strike Reinforcing — 14 gauge conforming to template requirements, and closer reinforcing — 12 gauge.
