Window and door frame gaps are one of the biggest sources of lost energy in a home. Cold air gets in during winter. Heat pours in during summer. Most people never find the leak because it is not visible. It is just a thin gap along the frame, and it costs you on every bill.
This tape seals it. No tools. No contractor. No permanent changes to the frame.
Marine Grade, Not Hardware Store Grade: Bargain window tape cracks, curls, and peels when temperatures swing. This tape is built to the same standard as boat weatherproofing. UV resistant, waterproof, and engineered to hold through full freeze and thaw cycles. It does not know the difference between a Miami summer and a Minnesota winter.
100 Feet Per Roll: One roll covers 100 linear feet of frame at 2 inches wide. That is enough for multiple windows and doors in a single application.
Safe for Renters and Landlords: No sticky residue. No surface damage. The tape sticks firmly to glass, wood, and painted trim, then peels off cleanly with gentle heat. Safe for deposit inspections. Safe for rental properties.
Three Colors to Match Any Frame: Choose clear for a nearly invisible seal, white for painted trim and vinyl frames, or black for dark casings and modern windows. Available as a single roll or a 2-pack for whole-home coverage.
