WINFLASH – Window and Door Flashing Membrane

07 25 00

DESCRIPTION
WINFLASH is a self-adhering, flexible membrane flashing tape which is nominally 20 mils thick. When properly applied, the product acts as a moisture barrier and reduces the risk of rot and mold development.

USES
WINFLASH provides protection against water infiltration in critical detail areas, such as window and door openings, deck-to-wall intersections, corner boards, wall-to-wall tie-ins, foundation sill plates, sheathing panel seams, under stucco finishes, masonry walls, and other non-roof detail areas.

FEATURES/BENEFITS

• Specifically formulated to block the ingress of moisture into the home environment.
• Self-adhering – easy application with hand roller.
• Multiple widths available to meet stringent moisture protection demands.
• embrane is flexible – will remain in place during period of movement.
• Self sealing.
• Superior adhesion.

APPLICATION
SURFACE PREPARATION
Apply WINFLASH in fair weather conditions when the air, surface, and membrane are at temperatures of 40° F or higher. Install directly onto a clean and dry surface. Remove dust, dirt, and loose nails. Protrusions must be removed. Surfaces should have no voids or damaged/unsupported areas. Repair surfaces before installing. Surfaces should be free of scale, rust, grease, and oil.

APPLICATION METHOD
Cut WINFLASH to desired length. Peel back the release paper to expose adhesive. Align the membrane and roll press into place with heavy pressure. Laps must be a minimum of 3″ (75 mm). Consistent with good construction practice, install the membrane so that all laps shed water (following the shingle principle). The top membrane layer should go over the bottom layer. Always work from low point to high point. Test adhesion – if extra adhesion is required, apply MEL-PRIME_™ or MEL-PRIME W/B from W. R. MEADOWS.

WARRANTY:
From 10 years of purchase, W. R. MEADOWS, INC. will replace any defective material exhibiting signs of moisture intrusion. W. R. MEADOWS is not responsible for any collateral damages due to this moisture penetration; only material replacement.
