Pemko 315CN 36 – Frequently Asked Questions

1) Can the Pemko 315 door sweep be used on a labeled fire door?
Fire rated to UL10C, and also carried under Underwriters Laboratory 4L10, so the 315 sweep is built for labeled openings. It also meets ANSI/BHMA A156.21. The aluminum retainer and EPDM insert are the sealing components, and the sweep mounts to the face of the door rather than into it, so nothing about the fire door assembly gets cut or bored to fit it. As always on a labeled opening, the sweep has to be consistent with the door and frame manufacturer's listing for that assembly.
2) Do I have to remove the door or machine it to install a Pemko 315 sweep?
No door prep at all. The 315 is a surface-mount sweep: the aluminum retainer fastens to the face of the door at the bottom, so the door stays hung and nothing gets mortised, bored, or cut. That makes it a straight swap when an old sweep has gone flat or the rubber has torn out, and it is the reason it works on doors already in service in occupied buildings rather than only on new leaves.
3) Is there enough room to mount a Pemko 315 sweep on a narrow bottom rail?
Plan on 1-11/16 inches of height for the profile and 1/4 inch of thickness. That is the whole sweep, retainer plus EPDM insert, so on an aluminum storefront door or a flush door with a shallow bottom rail, measure the clear band at the bottom of the leaf before you commit. Where the rail is shallower than that, or where glass runs close to the bottom, a lower profile bottom seal or a door shoe that wraps the bottom edge is the better fit.
4) What is the closest neoprene door sweep equivalent to the Pemko 315?
The NGP 197NA Neoprene Door Sweep pairs a neoprene seal with an anodized aluminum housing, which is the same material pairing the Pemko 315 uses: an EPDM neoprene insert carried in an aluminum extrusion. The Cal-Royal BTN-112 is the other close match, built as an extruded aluminum retainer with a neoprene insert. Confirm the length you need and the finish before you swap, since the 315 is sold in a 1-11/16 inch by 1/4 inch profile and in mill finish extruded bronze, black suede powder coat, clear anodized aluminum, and dark bronze anodized aluminum.
5) What door sweep should I use on a boiler room or commercial kitchen door that sees high heat?
For an opening that swings through extreme temperatures, the NGP 200SA Silicone Door Sweep is rated for a temperature range of -100 F to 500 F and mounts in an anodized aluminum housing. The Pemko 315 seals with an EPDM neoprene insert in an aluminum extrusion and carries UL10C fire rating, ASTM E90 sound testing, and ASTM E-283-04 air infiltration testing, so it is the one to specify when the drawing calls out those tests on a commercial opening. Match the elastomer to what the mechanical room actually runs at, then confirm door width against available lengths.
6) Should I use a door sweep or a door shoe at the bottom of the door?
Two different mountings for the same gap. The Pemko 315 is a sweep: it screws to the face of the door and the EPDM insert drags across the floor or threshold, which is why it goes on without touching the door itself and comes off just as easily when the rubber wears. A door shoe wraps the bottom edge of the leaf instead, which usually means pulling the door to install it but puts the seal down on the threshold rather than out on the face. For retrofit work on doors already hanging, the sweep is the lower disruption answer.
7) Will a Pemko 315 sweep help with noise and drafts coming under an office door?
That is what the EPDM insert is there for, and the 315 has the test data behind it: sound tested to ASTM E90 and air infiltration tested to ASTM E-283-04. The bottom gap is normally the largest single opening left on a closed door, so closing it with a compliant rubber insert is the first move on both a noise complaint and a draft complaint. It is a commercial rated part, built for office, healthcare, education and multi-tenant traffic rather than occasional residential use.
8) What else can I use if the Pemko 315 sweep is not available in the finish or length I need?
Two close cross-brand matches on the same construction. The Cal-Royal BTN-112 is a door bottom sweep with an extruded aluminum retainer and a neoprene insert, the nearest equivalent build to the 315. The NGP 197NA is a neoprene sweep in an anodized aluminum housing, which is the one to look at if you are matching anodized storefront hardware. Both are rubber insert sweeps in aluminum, so they mount to the door face the same way the 315 does.
9) What finishes does the Pemko 315 sweep come in for matching hardware across a building?
Four: clear anodized aluminum, dark bronze anodized aluminum, black suede powder coat, and mill finish extruded bronze. Every finish is available in all five lengths, so a portfolio with 36 inch office doors and 48 inch service doors can be standardized on one look. Clear anodized is the usual match for aluminum storefront and clear anodized frames; dark bronze anodized pairs with bronze storefront systems; black suede powder coat is the flat black option for painted hollow metal.
10) I need new sweeps to match the anodized aluminum ones already on my building's doors. What are my options?
The Pemko 315 is offered in clear anodized aluminum and in dark bronze anodized aluminum, along with black suede powder coat and mill finish extruded bronze, in 36, 40, 42, 48, and 84 inch lengths. If you are mixing brands across a property, the NGP 197NA neoprene sweep and the NGP 200SA silicone sweep both use anodized aluminum housings as well. Anodized tones vary between manufacturers, so if the doors are in one line of sight, hold the whole run to a single model and finish and let brand mixing fall on separate wings or buildings.
11) Which door sweep holds up best in a walk-in cooler or freezer opening?
Cold service is where the elastomer choice shows. The NGP 200SA is a silicone sweep rated from -100 F to 500 F in an anodized aluminum housing, which covers the low end of refrigerated openings. The Pemko 315 uses an EPDM neoprene insert in an aluminum extrusion and is built for commercial service with ASTM E-283-04 air infiltration testing, which is what matters on the conditioned side of a building envelope. For a cooler or freezer door, confirm the low temperature the seal will sit at continuously, then pick the material rated for it.
12) Is the Pemko 315 sweep suitable for an exterior entrance door?
Yes. It is a commercial rated part built on an aluminum substrate, and the finish options include clear anodized and dark bronze anodized aluminum for exterior exposure. Air infiltration testing to ASTM E-283-04 is the relevant number for an entrance: that is the standard for how much air leaks past the assembly, which is what drives the draft and the energy loss at a main door. The EPDM insert does the sealing against wind driven rain, dust, and air at the threshold.
13) Can I replace just the rubber on a worn Pemko 315, or do I buy the whole sweep?
The 315 is sold as a complete assembly, the aluminum retainer with the EPDM insert in it, in the length and finish you order. Since it surface mounts to the door face, swapping the whole unit is a screwdriver job on a hanging door, so most maintenance crews stock a few lengths in their building finish and change the assembly rather than chase inserts.
