ALIEN TAPE Door & Window Draft Seal — 49 ft Transparent Silicone Strips, Moisture-Resistant Adhesive

ALIEN TAPE Draft Seal is a flexible, adhesive silicone flap system that seals gaps around doors and windows to reduce drafts and block cold air.

Keep warm air inside and stop chilly drafts with this 49-foot set of transparent, moisture-resistant sealing strips. The kit includes three rolls (1.4" wide x 16.34 ft each) designed to adhere to wood, glass, metal, plastic and ceramic surfaces. Because the strip is made from premium-grade silicone and uses a durable adhesive, it flexes with door movement while resisting peeling from moisture or light splashes.

How will this seal kit improve my home's insulation?

The seal creates a continuous barrier that prevents air exchange through gaps under doors and around window frames. Reducing uncontrolled airflow helps maintain indoor temperatures and reduces the workload on heating systems.

• Blocks drafts at thresholds and window edges.
• Reduces cold air infiltration that causes heat loss.
• Keeps conditioned air where you want it, improving comfort.
• Works on flat and slightly uneven surfaces thanks to flexible silicone.

What surfaces and openings can I use these strips on?

ALIEN TAPE adheres to a broad range of materials and works for door bottoms, sliding doors, window sashes and even as a shower door seal. Its adhesive bonds to painted wood, powder-coated finishes, glass, metal, plastic and fiberglass.

• Door bottoms and thresholds—creates a sweep-style seal.
• Window gaps—applies along sills and frames for sash sealing.
• Shower doors—helps keep water from escaping while remaining discreet.
• Garage doors and patio sliders—flexible for larger clearances.

How easy is installation and maintenance?

Installation is a straightforward cut-and-stick process: measure, trim to size, then press the adhesive backing onto a clean surface. The transparent finish minimizes visual impact, and the material stays pliable in cold weather so it continues working without regular adjustments.

• Measure, cut with scissors, peel backing, press firmly into place.
• Transparent profile stays unobtrusive while sealing gaps.
• Moisture-resistant adhesive prevents lifting from splashes or humidity.
• Occasional cleaning with a damp cloth keeps the strip looking neat.

Will this product last through winter and damp conditions?

The strips are made from premium silicone engineered to resist hardening and cracking over time. With a super-strong adhesive formulated for moisture-prone areas, the seal remains flexible and adherent through cold, damp seasons.

• High-grade silicone resists creasing and stiffening in low temperatures.
• Adhesive designed to withstand humidity and light water exposure.
• Durable construction reduces the need for frequent replacement.
• Transparent design resists staining and blends with trim.
