CRL 25 mil 9" x 75' Fortifiber FortiFlash® Waterproof Flashing

CRL Fortifiber FortiFlash® Waterproof Flashing is a top-tier self-adhesive waterproof membrane, perfect for windows and non-roofing horizontal surfaces like pot shelves and recessed windows.
Strengthened by cross-laminated high-density polyethylene film, this rubberized asphalt core membrane excels at sealing common through-wall penetrations.
Offered in 25 and 40 mil thicknesses, the 25 mil version is ideal for tight corners, while the 40 mil option caters to applications requiring a thicker product.
For optimal application, clean the window flange and base layer before cutting the desired length, then remove the release paper and apply with firm pressure for a thorough seal.
