WEATHERMATEâ„¢ Straight Flashing combines a BLUEâ„¢ high-density polyethylene (HDPE) film facer with a butyl rubber adhesive to form a strong mechanical and chemical bond to most building materials. A polymeric-coated paper release liner provides a more consistent peel than plain paper liners.
Building Code Compliance
Meets requirements of ASTM E2112, ICBO AC148-01 and AAMA 711-05.
Commercial
WEATHERMATE™ Straight Flashing is a self-sealing, self-healing, fully adhered flashing engineered for excellent adhesion to insulated sheathing, steel, masonry, concrete, gypsum and wood. In commercial applications, it is used to protect the building from moisture intrusion at critical areas, such as between joints of insulation on steel stud cavity walls and as temporary flashing over insulation joints on standing seam metal roofs, enhancing total building performance.
In the United States, WEATHERMATE™ Straight Flashing is also a component of the THERMAX™ Wall System.
