NGP 220WHA-36 – Frequently Asked Questions

1) Will the NGP 220WHA automatic door bottom work on a doorway with no threshold and carpet on the floor?
That's exactly what the nylon brush seal is for. NGP recommends the brush version for carpet applications where no threshold is provided, because the brush makes gentle contact with the floor rather than dragging a solid insert across pile. With a 7/8 inch maximum drop, it will reach down to carpet in most standard undercuts.
2) Which side of the door does the NGP 220WHA mount on, and does handing matter when ordering?
It surface mounts on the push side of the door. Handing does matter: NGP supplies a right hand configuration unless you specify otherwise, so state the hand on the order if the opening is left hand. End caps come with the unit as standard.
3) What is the difference between an automatic door bottom and a regular door sweep?
A sweep like the Pemko 345 Series is fixed: the insert rides against the floor all the time. An automatic door bottom such as the NGP 220WHA has a plunger that drops the seal only when the door closes, so the seal stays clear of the floor while the door swings. That matters on carpet, on ADA-sensitive openings, and anywhere a dragging sweep would wear out fast. If you want an automatic bottom from another brand, the Pemko SA Series surface mount automatic door bottom is the comparable type.
4) What is the closest equivalent to the NGP 220WHA automatic door bottom from another manufacturer?
The Pemko SA Series surface mount automatic door bottom is the nearest counterpart. Like the NGP 220WHA, it is an automatic door bottom that mounts to the face of the door rather than being mortised into it, and Pemko offers it in a 36 inch length matching one of the 220WHA lengths. The difference is the seal material: the 220WHA carries a nylon brush seal on an aluminum alloy 6063 T5 extrusion, while the Pemko SA Series uses a GREENGUARD Gold certified Eco-V insert.
5) Is a Pemko 345 door sweep a substitute for an NGP 220WHA automatic door bottom?
No, they are different devices. The Pemko 345 Series is a door bottom sweep with a rain drip and a PemkoPrene insert, so the seal rides against the floor continuously whenever the door swings. The NGP 220WHA is an automatic door bottom: the seal is held up until the door closes, then drops up to 7/8 inch. If the floor is carpeted with no threshold, or you need the seal clear of the floor while the door operates, the 220WHA is the right part. If you simply need a fixed sweep with exterior rain protection, the 345 Series is the one that adds the rain drip.
6) Can an automatic door bottom like the NGP 220WHA be used on a hot kitchen or mechanical room door?
The operating range runs from -70 F to 425 F, which covers unconditioned mechanical spaces, freezer vestibules, and hot back-of-house areas. The frame is 6063 T5 aluminum alloy with synthetic polyamide working parts, chosen for abrasion resistance across that span.
7) Is the NGP 220WHA suitable for a healthcare or school facility specification?
It is a commercial rated product and NGP lists healthcare institutions, educational facilities, government buildings, and multi-tenant residential among its applications. Materials are REACH and RoHS compliant, which covers most institutional environmental submittals. If your spec calls for a GREENGUARD Gold certified insert specifically, the Pemko SA Series automatic door bottom with the Eco-V insert is the option that carries that.
8) Will a brush seal actually stop drafts and sound, or should I use a solid insert?
The 220WHA's nylon brush closes the gap for air infiltration and sound transmission at up to 7/8 inch of drop, and the synthetic polymer resists moisture while keeping its flexibility and memory. Brush is the right call on carpet or uneven floors where a solid insert would not seat evenly. Over a flat threshold or smooth floor, a solid insert version gives tighter contact.
9) For a LEED or low-emitting materials spec, which door bottom should I use instead of the NGP 220WHA?
The Pemko SA Series surface mount automatic door bottom uses a GREENGUARD Gold certified Eco-V insert, which is the one to cite when the submittal calls for a certified low-emitting seal material. The NGP 220WHA answers a different environmental requirement: its materials are REACH and RoHS compliant. Both are surface mounted automatic door bottoms, so the door prep does not change between them.
10) I need a simpler door bottom than an automatic one for an interior office door. What are my options?
A fixed door bottom sweep such as the Pemko 345 Series is the simpler approach: it has no drop mechanism, just a PemkoPrene insert that seals against the floor, and it is offered in a 36 inch length. Compared with the NGP 220WHA, you give up the ability to lift the seal clear of the floor, which matters over carpet or an uneven finished floor where a fixed sweep would drag. The 220WHA holds its nylon brush seal up until the door closes and then drops up to 7/8 inch.
11) Which door bottom should I use on an exterior door that needs rain protection?
For an exterior opening where water running down the face of the door is the concern, the Pemko 345 Series door bottom sweep includes a rain drip along with its PemkoPrene insert, which diverts runoff away from the sill. The NGP 220WHA is an automatic door bottom with a nylon brush seal that mounts on the push side and drops up to 7/8 inch; it is the choice for interior openings over carpet where no threshold is provided, and it does not incorporate a rain drip.
12) I need to match existing hardware finishes in my building. What finishes does the NGP 220WHA automatic door bottom offer?
Two: anodized aluminum (clear, mill look) and dark bronze. Both are available in the 36, 48, and 60 inch lengths, so you can standardize the finish across openings of different widths.
