Vycor Plus


Extends Proven Technology of Grace Ice & Water Shield® to Critical Non-Roof Applications

CAMBRIDGE, MA, July 6 – Grace Construction Products, a world leader in the construction products industry, has introduced Vycor Plus Self-Adhered Flashing, a flexible, rubberized, weather-resistive barrier specially created for leak protection in critical non-roof detail areas.

Vycor Plus Self-Adhered Flashing provides enhanced protection against water, air and moisture infiltration in areas such as window and door openings, corner boards, under stucco finishes, masonry walls, and other flashing details. It is designed to work in severe winter climates, milder climates, and in coastal areas where wind driven rain is common.

In masonry construction, Vycor Plus is ideal for sealing joints, seams, holes, and other unwanted openings in wall sheathing systems. This flashing has been designed for compatibility with housewraps and felts, and should not be used on the roof.

"Vycor Plus answers a direct customer need for improved air and moisture protection around penetrations in exterior wall systems, and reinforces our commitment to innovation," said John O'Connell, North American Product Manager for Grace Construction Products. "For maximum protection against leaks in critical wall penetrations, Vycor Plus provides a level of protection that traditional building papers, felts, and housewraps just can't match."

Vycor Plus Self-Adhered Flashing is available in 75' length rolls in widths of 4", 6", 9", and 12" to accommodate a variety of job requirements. It is 25 mil thick, and composed of two waterproofing materials - rubberized asphalt and cross-laminated polyethylene covered with a paper release liner. Vycor Plus is compatible with wood, plywood, oriented strand board, concrete and masonry, and fully adheres to the substrate to prevent water from passing through and into the structure.

Vycor Plus Self-Adhered Flashing employs the same proven technology as Grace Ice and Water Shield® self-adhered roofing underlayment – the market leader for over twenty years.
