Why Grace Vycor Plus TM Flash it right. WHY GRACE VYCOR PLUS? There are a number of flashing materials available on the market today.

How to Apply Grace Vycor Self-Adhered Flashing Tapes PRE-INSTALLATION NOTES • ASTM E2112-01* and AAMA 2400-02* recommend the use of a minimum 9 inch wide flashing membrane beyond the rough opening. • Grace recommends a 12 inch wide flashing membrane for proper waterproofing of the window sill, providing a drainage plane in the rough opening. • Remove any weather-resistive barrier from sill area prior to membrane installation for full adhesion of the membrane to the structural sill.

Tips from the Pros... you’ll save time and money WHAT THE PROS SAY John Kurowski, Owner Kurowski Development “When it comes to installing flashing tapes around windows and doors, it is important to use quality materials installed properly. Grace’s instructional CD clearly supports the old saying ‘a picture is worth a thousand words.’ That kind of field support helps me instruct our trade contractors better, and helps me be a better builder.
Tips from the Pros... you’ll save time and money WHAT THE PROS SAY Joe Lstiburek, Ph.D, P. Eng. Principal, Building Science Corp. “Mold problems cannot exist without water problems. No water problems, no mold problems. The sooner the water is directed out of the building structure, the better. The best expression of this concept is a flashing. Flashings are the most underrated building enclosure component and arguably the most important.
