WEATHERMATE™ Flashing is a selfsealing, self-healing, fully adhered flashing engineered for exceptional adhesion to insulated sheathing, steel, masonry, concrete, gypsum and wood. It is used to protect the building superstructure from moisture intrusion at critical areas such as between joints of insulation on walls and as a temporary flashing over insulation joints on standing seam metal roofs, enhancing total building performance.

WEATHERMATE™ Flashing combines a BLUE™ high-density polyethylene (HDPE) film facer with a butyl rubber adhesive that forms 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.
WEATHERMATE™ Flashing contains no asphalt. The butyl rubber adhesive technology, a key component of this flashing, is considered superior to asphalt adhesives in compatibility with commonly used building envelope caulking materials, insulated and non-insulated sheathing, housewraps and window casing materials.
