Frequently Asked Questions

1. What is the difference between a door sweep and a door bottom? A door sweep is typically surface-mounted to the face of the door and uses a strip of material (like neoprene or brush) to seal the gap. A door bottom (often called an automatic door bottom) is usually mortised into the bottom of the door or wrapped around it, providing a more heavy-duty seal that can drop down when the door closes.

2. Which material is best for an uneven floor? If your floor or threshold is uneven, a Nylon Brush Sweep is the best choice. Unlike solid rubber or neoprene, the individual bristles of a brush sweep can contour to the dips and rises in the floor, ensuring a consistent seal against pests and drafts.

3. Are all door sweeps fire-rated? No, not all sweeps are fire-rated. For fire doors, you must look for products that are UL Listed or Grade 1 rated for smoke and draft control. Materials like Neoprene and Silicone are commonly used in fire-rated applications because they maintain their seal integrity under high heat.
