What is a flashing?
Flashings seal a wall where it's most susceptible to water, air and moisture leaks. Most commonly, these are found in window and door openings, corner boards, deck-to-wall intersections, under stucco finishes, masonry walls and other detail areas.
How do flashings work?
Window and door flashings are installed prior to the exterior finish covering. They work by sealing the joints, seams, holes and other unwanted openings in walls so that water and air cannot pass through the substrate and into your home. Grace window and door flashings provide superior protection against leaks that traditional building papers, felts and house wraps just can't match.
What are Grace flashings composed of?
Grace Vycor Plus and Grace Vycor V40 are composed of two excellent waterproofing materials: rubberized asphalt and cross-laminated polyethylene.
How is Grace Vycor® Plus different from Grace Vycor® V40?
Grace Vycor Plus is a 25 mil self-adhered flashing that provides premium protection against water, air and moisture leaks. It is designed to work in severe winter climates, milder climates and in coastal areas where wind-driven rain is common. It can be safely used with wood, plywood, concrete and masonry. Grace Vycor V40 Weather Barrier Strips offer this same protection in 40 mil. Grace Vycor V40 is also specifically designed to meet the federal code for weather-resistive barriers (see Federal Specification UU-B-790a, Grade A).
How long can Grace flashings be exposed?
They are not meant to be permanently exposed to the sun, but can be safely
exposed for up to 30 days. Grace Vycor Deck Protector may be exposed to
indirect sunlight for longer periods time. Check product literature for
more information.
Can Grace flashings be used on roofs?
No! Although Grace window and door flashings use the same waterproofing
technology as our roofing underlayments, they have different chemical
formulations, making them inappropriate for roofing applications. They
are also very slippery and come in narrower widths. For roof detailing – use
Grace Roof Detail Membrane.
