DuPont flashing tape helps protect the heads and jambs of rectangular doors and windows from air and water intrusion. Wind-driven rain and outdoor air can find their way into walls around windows and doors. By helping to seal the building envelope, self-adhered DuPont Flashing Tape can help reduce the risk of water damage, increase building comfort and improve energy efficiency.

• • Air resistance to help prevent the flow of air through wall cavities and reduce drafts
• • Moisture resistance to help protect the wall cavity from water that gets behind the cladding
• • Moisture vapor permeability to promote drying of wall systems
• • Durability to withstand the rigors of the construction site and to continue performing once construction is completed
• • Self-adhered and 100 percent butyl-backed flashing tape
