M-d Building Products 63644 Epdm Weatherstrip 10 Ft Brown

Product Description

The M-D BUILDING PRODUCTS 63644 is a 10-foot roll of self-adhesive EPDM cellular rubber weatherstrip designed to seal extra large gaps around doors and windows. Constructed from 100% EPDM (Ethylene Propylene Diene Monomer) cellular rubber, the strip blocks drafts, dust, and moisture ingress at the door top, latch side, or a standard window perimeter. The material stays flexible across a wide temperature range, from -40 degrees F to 140 degrees F, making it suitable for both cold-climate and high-heat installation environments. A licensed contractor or experienced tradesperson can apply this strip quickly using the integrated self-adhesive backing without additional adhesive or fasteners.

This weatherstrip is intended for residential and light commercial use on standard exterior doors and windows where gaps exceed the capacity of standard-profile seals. The all-profile design accommodates extra large gaps that typical foam or vinyl strips cannot adequately fill. One 10-foot roll covers the top and latch side of a single door or one average-size window. It is well suited for retrofit weatherization work, energy-efficiency upgrades, and draft remediation on existing door and window frames.

Key Features

• 100% EPDM cellular rubber construction resists moisture, dust, and air infiltration
• All-profile design seals extra large gaps where standard weatherstrip falls short
• Remains flexible from -40 degrees F to 140 degrees F for year-round performance
• Self-adhesive backing allows tool-free installation on door tops, latch sides, or window frames
• 10-year flexibility guarantee per manufacturer specifications
• Single roll covers the top and latch side of one door or one average-size window

Compatibility

Designed as an OEM-style replacement and retrofit weatherstrip for standard residential exterior doors and average-size windows requiring an extra large gap seal profile.

Installation Notes

Installation is typically performed by a general contractor, weatherization technician, or knowledgeable tradesperson. Clean the mounting surface thoroughly and allow it to dry completely before applying the self-adhesive backing, as residual dirt or moisture will reduce adhesion. No special tools are required, but a utility knife is recommended for trimming the strip to length. Do not stretch the strip during application, as this can reduce long-term seal integrity.
