Weather Stripping

Weather Stripping

Weather stripping includes door seals, gaskets, sweeps, perimeter seals, meeting stile seals, and related sealing hardware.

The collection is associated with exterior doors, commercial doors, frame openings, thresholds, door bottoms, and meeting points between door panels.

Common material families include aluminum carriers, vinyl seals, neoprene, silicone, nylon brush, and other door sealing components.

Door Weather Stripping: Frame Seals vs. Door Bottoms

Door weather stripping seals different parts of the opening. Perimeter gaskets and adhesive weatherstrip fit compatible gaps at the jamb and header; brush weatherstripping and retainer-mounted profiles serve other frame and door conditions. Below the door, a surface sweep or door shoe can contact the threshold or floor, while an automatic door bottom is designed to lower its seal as the door closes. These products are not interchangeable simply because they all reduce drafts.

Measure the door width, bottom clearance, frame gaps, mounting surface and existing hardware before choosing a replacement. Compare the gasket profile, retainer width, seal projection, fastening method, door swing and any cut-to-fit limits. For a mortised automatic bottom, confirm the exact door preparation and activating mechanism; for adhesive seals, verify that the mounting surface and clearance suit the specified product.

Shop Door Seals, Gasketing and Threshold Hardware

Browse Pemko door seals and weatherstripping, National Guard Products sealing hardware and door thresholds for related commercial-opening components. The available assortment includes adhesive perimeter gasketing, brush seals, rain drips, door shoes, sweeps, automatic door bottoms and selected threshold profiles. Compare the listed dimensions and materials on each product; not every seal is intended for every door or frame.

Material and performance requirements matter as much as size. Vinyl, neoprene, silicone and nylon brush seals have different profiles and intended contact surfaces. For smoke-, fire- or sound-rated openings, check the exact product listing and the complete assembly requirements before modifying a door, frame or threshold. Finish and exposed retainer material can be chosen after the opening's sealing function and fit are confirmed.
