Pemko 5110BL-120-12 – Frequently Asked Questions

1) Will Pemko 5110 mullion gasketing seal the gap between a pair of doors without a mullion?
That is exactly what the 5110 is for. It's an adhesive-backed astragal gasket that seals the meeting stiles of double doors, applied to the astragal or the edge of the inactive leaf. At 1-1/8 inches wide and 3/16 inch high, it takes up a small meeting-stile gap; it is a gasket, not a structural astragal, so if there is no astragal on the pair you still need one to carry it.
2) Can I use Pemko 5110 gasketing on a fire rated door pair?
Yes. The 5110 neoprene gasketing is BHMA certified and carries UL10B negative pressure and UL10C positive pressure fire ratings, so it can go on a fire rated assembly. It also meets ANSI R0C004.
3) Does Pemko 5110 astragal gasketing need screws, or is the adhesive enough?
No fasteners. The 5110 is self-adhesive, with the adhesive backing already on the neoprene, so it goes on with a clean, dry surface and hand pressure. That matters on a metal astragal you don't want to drill, and it means no fastener heads sitting in the meeting stile gap where they'd catch the other leaf.
4) Is neoprene gasketing the right choice for an exterior door pair, or should I use something else?
Neoprene is the substrate on the 5110, and it holds up to weather and stays flexible, which is why it's used on commercial exterior pairs. Where it earns its place is compression sealing at the meeting stile: it's a soft closed section that takes a set-and-recover squeeze rather than a wiping action. If the gap you're fighting is at the bottom of the door or along the frame rabbet, this is the wrong part; that's a door bottom or perimeter gasketing job.
5) What is the Pemko part number for 120 inch black astragal gasketing?
The model is Pemko 5110, ordered as 5110BL-120 for the black neoprene in the 120 inch length. BL is the black neoprene designation and 120 is the length in inches.
6) Is Pemko 5110 gasketing rated for commercial traffic or is it a residential weatherstrip?
Commercial. The 5110 is specified as a commercial product and is used in offices, schools, healthcare, retail, warehouse, multi-tenant residential, and government buildings. For a property manager standardizing across a portfolio, one part number covers the double-door openings in all of those building types.
