What Is a Silicon Door Gap Filler?
A silicon door gap filler is a flexible rubber sealing strip installed at the bottom of doors to close the gap between the door and the floor. Unlike traditional draft stoppers that sit loosely, this self-adhesive strip attaches directly to the door, creating a continuous barrier.
It acts as a draft guard, insect blocker, dust protector, and noise reducer—all in one compact design. Because it uses silicone material, it remains flexible, durable, and resistant to wear over time.
