Zero International 328AA-36 – Frequently Asked Questions

1) Will the Zero 328AA perimeter seal fit my door frame, and what lengths does it come in?
The 328AA is a head and jamb perimeter seal that mounts to the frame stop, so you size it to the frame rather than the door. It comes in 36, 48, and 84 inch lengths: the 36 and 48 inch pieces are the usual choice for a head, and the 84 inch piece covers a jamb leg on a standard 7 foot opening. A typical single opening takes three pieces, one head and two jambs. The extruded aluminum can be cut down on site to suit the exact frame.
2) How much room does the Zero 328AA seal take up on the frame stop?
The 328AA profile is 1 inch wide and .219 inch high, so it needs a stop face of at least an inch to sit flat and it projects roughly a quarter inch off that face. On a narrow stop, or where the door already fits tight to the stop, measure the stop before ordering. The neoprene bulb does the sealing, so the door has to close against it with a little compression.
3) Do I need a door sweep as well as the Zero 328AA perimeter seal?
Yes. The 328AA seals the head and the two jambs only. The gap under the door is a separate part, either a door sweep on the face of the door or a door bottom, and on a smoke or fire rated opening that bottom gap has to be addressed for the assembly to do its job. Buyers commonly pair a perimeter seal like this with a sweep or an automatic door bottom from the same Zero line.
4) Is the Zero 328AA rated for smoke and sound on a commercial opening?
The 328AA is rated as a sound seal, smoke seal, fire seal, and air seal, and it is a commercial product rather than a residential one. That combination is why it turns up on hospital corridors, school classrooms, and multi tenant corridor doors where one gasket has to handle acoustics and smoke at the same opening.
5) How does the 328AA install, and does it need special tools or adhesive?
Screw mount. The aluminum housing is drilled and fastened to the frame stop, so it holds its position and can be re-tightened later, unlike adhesive backed foam gasketing that has to be stripped and replaced when it lets go. For a fleet of openings that gets re-gasketed on a cycle, the screw mounted extrusion is the one that survives the second and third replacement of the insert.
6) Solid neoprene or a vinyl bulb seal, which should I use for a perimeter seal?
The 328AA carries a solid neoprene insert. Solid neoprene compresses under the door and takes a set less readily than a hollow vinyl bulb, which is what you want on a door that gets heavy traffic or slams. It is also the choice where the opening needs a sound seal rather than just a draft stop. A hollow bulb closes easier on a light door with a weak closer, but it is the less durable of the two on a busy corridor.
7) Will the clear anodized finish on the Zero 328AA match my existing aluminum frames?
Clear anodized aluminum reads as a natural silver, so it sits alongside clear anodized storefront and aluminum frames without standing out. Against a dark bronze anodized frame or a painted hollow metal frame it will contrast, and on a run of doors that has to look uniform you would want the same finish on every opening.
8) What is Compress-O-Matic on the Zero 328AA and why does it matter?
Compress-O-Matic is Zero's compressing seal design: the neoprene gives as the door closes into it and recovers as the door swings away, so the seal keeps contact as the door shifts and settles over time. On an opening where the door has racked slightly or the closer is set light, a compression seal keeps sealing where a rigid one would leave a gap.
