Alien Draft Seal - Transparent Silicone Seal Strip, 6 Rolls (Set of 2) for Gaps Around Doors and Windows

Overview

Alien Draft Seal is a transparent silicone seal strip that helps close gaps and reduce drafts around doors, windows, and showers. The premium, clear material blends with most décor while delivering a practical, flexible seal. The kit includes three rolls you can cut to length, giving you a customized fit for multiple spaces. Sold as a set of two packs, this means six rolls in total for larger projects.

Why it stands out

The seal uses Flex-Flap technology to adapt as you move, delivering a tight seal at the edge of each gap. The peel-and-stick backing makes installation straightforward on wood, glass, tile and metal. The nearly invisible barrier blocks wind and moisture while allowing smooth operation of doors and shower doors.
