M-d Building Products 71522 Caulking Cord Weatherstrip

Product Description

The M-D BUILDING PRODUCTS 71522 is a flexible, self-adhesive caulking cord weatherstrip designed to seal gaps around doors and windows in residential and light commercial applications. The cord measures 3/16 inches wide by 1/8 inches thick and comes in a 30-foot roll, providing enough material for multiple openings in a single job. Its white finish blends with common interior and exterior trim. The foam-style cord compresses into irregular gaps, blocking drafts, dust, and moisture at the point of entry. No tools are required for installation, making it a practical option for weatherization tasks where adhesive-backed materials are acceptable.

This caulking cord is suited for sealing perimeter gaps on single or double-hung windows, sliding doors, and door frames. It can be applied to both interior and exterior surfaces. The product also serves as a temporary or supplemental seal for cracked window panes. Installers, property maintenance technicians, and knowledgeable DIYers use this strip during weatherization inspections, pre-season audits, or as part of a broader air-sealing scope. Its flexibility allows it to conform to uneven or irregular surfaces where rigid weatherstripping would leave voids.

Installation Notes

Installation does not require licensed trade work and falls within the scope of general building maintenance or weatherization. Clean the application surface thoroughly and allow it to dry completely before pressing the adhesive backing into place, as oil, dust, or moisture will reduce adhesion. Ensure the gap being sealed is within the dimensional range the cord can compress to fill without buckling. For exterior applications, confirm the surface temperature is within the adhesive manufacturer's recommended range to ensure proper bond.
