M-d Building Products 43200 Door Window Draft Seal 36 in

Product Description

The M-D BUILDING PRODUCTS 43200 is a foam-core door and window draft seal designed to block unwanted airflow at the base of doors and along window frames in both interior and exterior applications. The foam insert is enclosed in a washable cloth cover in a brown finish, allowing it to blend with common door finishes while remaining easy to maintain. At 36 inches in length, it fits standard residential door widths without cutting or trimming. No tools or hardware are required for installation, making this a practical solution for HVAC efficiency maintenance and weatherization work.

This draft seal is suited for residential applications where conditioned air loss at door bottoms and window frames is a service concern. It slides underneath a door to create a barrier against drafts and helps reduce heating and cooling losses through gaps at the floor line. The washable cloth cover extends service life in high-traffic areas. It is commonly installed as part of a weatherization package in residential retrofit or energy audit follow-up work.
