Product Details
DensDefy® Transition Membrane is an impermeable self-adhered sheet designed for use as a rough opening flashing and transition membrane for connecting dissimilar materials to maintain air and moisture barrier continuity. DensDefy® Transition Membrane bonds to most surfaces such as glass mat gypsum sheathing, poured concrete, masonry, steel, and wood based substrates.
FEATURES AND BENEFITS
- The high-performance butyl has been tested as is compatible with the DensElement® Barrier System.
- Primerless application allows for faster installation time.
- Manufactured to a preset, uniform thickness that will not create excessive build up in rough openings while still providing exceptional strength/durability.
- Rugged HDPP film protects high-performance butyl membrane against incidental damage during the construction process.
- Variety of widths available for project specific needs.
- Ability to be installed in a wide range of temperatures.
