EternaBond WS-3-50, 3″ by 50 Foot Roll – Special 3 Inch Size

WS- Window Seal – Designed as an Air and Vapor Barrier for Window Installations

WindowSeal Tape is a self sealing adhesive that creates a water tight seal between the window frame and virtually all structure surfaces. Irregular or curved surfaces are easy because Eternabond WindowSeal is extremely conformable. WindowSeal, if kept warm (room temperature+) prior to installation can be installed at temperatures as low as 20ºF, and as low as -20ºF with optional EternaPrime. No staples or nails required.

WindowSeal utilizes EternaBond’s advanced MicroSealant™ Technology, a 100% solids formulation of synthetic resins, thermoplastics, and non-curing rubbers, with a built in primer on a stretchable, low density polyethylene (LDPE) backing.

Permanently bonds to create a permanent, flexible seal to a wide range of surfaces including glass, wood, aluminum, vinyl, OSB, polyethylene, polypropylene, polystyrene, Tyvek™, fiberglass, brick, concrete, masonry, and virtually all construction materials.
