Thermwell SG30WH Garage Door Weather Seal 30 Ft White

Product Description

The THERMWELL SG30WH is an extruded vinyl weather seal strip designed to close gaps along the sides and top of overhead garage doors. At 30 feet in length, a single strip provides enough material to seal a standard two-car garage door perimeter. The white finish suits painted or primed door frames. Constructed from extruded vinyl, the seal compresses against the door surface to block drafts, dust, and moisture infiltration. Installation hardware is included — nails come with the strip so the job can be completed without a separate fastener run. This type of seal is a common maintenance item installed by general contractors, property maintenance technicians, and experienced DIYers.

This weather seal is suited for residential and light commercial overhead garage door applications. It is applied to the door stop molding along the vertical sides and horizontal top of the door opening. The 30-foot length accommodates most standard single or double garage door perimeters. The white color is appropriate for installations where the door frame or trim is painted white or will be painted to match. The included nails allow direct attachment to wood door stop molding without additional hardware.

Installation Notes

Installation is typically performed by a general contractor, handyman, or experienced DIYer using basic hand tools. Close the garage door fully before measuring and cutting the strip to length. Attach the seal to the door stop molding using the included nails, positioning the vinyl flange so it makes firm contact with the door face without binding the door travel. Cut vinyl with tin snips or a sharp utility knife for clean edges at corners.
