Weatherstripping

Weatherstripping is one of the simplest ways to improve energy efficiency and comfort in a space. It creates a tight seal around the perimeter of doors and windows, reducing heat loss, moisture intrusion, and ambient noise—all without compromising how the door operates.

CDM Hardware offers a wide selection of weatherstripping profiles in silicone, neoprene, and foam, each tailored to specific use cases—like heavy commercial doors, wood entry units, or retrofit applications. Some profiles are kerf-in for clean installation; others are surface-applied for on-site adjustability.

We guide clients in matching profile shapes to door gaps and substrate types. Whether you’re building to energy code or simply trying to reduce drafts in a heritage home, we help ensure the weatherstripping fits—and stays effective long after installation.
