Description

AIR-SHIELD SMP is a self-adhering, vapor-permeable sheet membrane air barrier that bonds directly to the substrate without primer or adhesive. It prevents air and liquid water intrusion while allowing vapor to escape, helping wall systems stay dry and energy efficient.
  • Self-adhering, vapor-permeable air barrier
  • Bonds to concrete, masonry, sheathing, metal, plywood without primer
  • Class A fire performance and high vapor permeability
  • ABAA and ASTM compliant
  • Installs cleanly across wide temperature range

Features

  • Helps reduce air and moisture intrusion
  • Bonds easily and securely to a variety of building materials - no primer required
  • High vapor permeability - allows transmission of moisture vapor
  • Highly flexible - bridges cracks in substrate
  • Tough, durable membrane resists punctures and tears

Includes

  • 1 roll of AIR-SHIELD SMP
