A door frame seal is a protective gasket or strip installed around the perimeter of a door frame to create an airtight, weatherproof, and often soundproof barrier when the door is closed. Made from materials like rubber, silicone, foam, or fire-resistant intumescent strips, it prevents drafts, moisture, dust, noise, and even smoke or flames (in fire-rated doors) from passing through gaps between the door and frame. Essential for both exterior and interior doors, it enhances energy efficiency by reducing heat loss, improves acoustic insulation, and ensures compliance with fire safety standards. Available in various types—such as compression seals, magnetic strips, or brush seals—it provides a durable, flexible seal that adapts to door movement while maintaining optimal performance.
