Door Sweeps, Weatherstrips & Thresholds
Signature Plastics produces extruded PVC profiles used in door sweeps, frame-applied weatherstrips, and threshold systems across residential, commercial, and OEM door applications. These profiles are designed to be cut, fitted, and integrated into finished door assemblies based on the door construction, frame type, and sealing requirements.
The product range supports common door sealing conditions, including under-door gaps, perimeter sealing at the jamb and head, and transitions at the threshold. Each profile is designed to suit specific door and frame conditions, with sealing performance tailored to the application. These profiles are supplied for fabrication, private-label programs, and distributor channels.
Our profiles are designed to integrate directly into your existing system design and tolerance requirements.
