The Grace Vycor® Plus 4″ Strip is a self-adhered flashing membrane designed to provide superior protection against water infiltration around windows, doors, and other vulnerable building envelope penetrations. Featuring a flexible, rubberized asphalt adhesive and durable cross-laminated polyethylene backing, Vycor® creates a watertight seal to help prevent leaks, drafts, and moisture damage.
The 4″ width is ideal for sealing smaller joints, seams, and narrow flashing applications while maintaining strong adhesion to wood, metal, masonry, and vinyl surfaces.
