Core Advantages

Superior Adhesion & Sealing

The robust rubberized asphalt forms a strong, tight bond directly to the roof deck while providing excellent sealing around penetrations and fasteners.
Enhanced Installer Safety

The top surface features an anti-skid, high-strength film that creates a highly slip-resistant walking surface for safer, easier installation.
Reliable, Watertight Laps

The membrane ensures watertight overlaps and utilizes a foldless bottom release liner that preserves maximum adhesive quality until the moment of application
Climate Resilience

Designed to perform across diverse climates, it offers good heat resistance alongside excellent low-temperature flexibility, resisting cracking even at -20.2°F (-29°C)
Versatile Applications

This underlayment is highly adaptable and is ideal for use under a wide variety of mechanically attached roof coverings, including asphalt shingles, slate, tile, cedar, and standing seam metal roofs

Applicable Acenarios

The substrate must be solid, flat, dry, and clean of debris, grease, or protruding nails before application. The membrane should be applied from the low point to the high point of the roof so that laps shed water naturally, maintaining a minimum overlap of 80mm on all seams. Roll the entire membrane firmly to ensure full substrate contact.
