Highest performing walkability and stability on roof slopes of 8:12
Innovative Technology for Category Leading Deck Stability and Walk-Ability

Built with leading elastomeric polymers, CastlePro UL25 resists sliding on OSB roof decks of 8:12, creating unparalleled performance and installation efficiency. The optimized textile walking surface is highly-resistant to pilling and provides improved performance in wet conditions. The high-tack backside prevents elongation around fasteners in areas of high traffic, providing excellent installed performance. Built for use in residential and commercial applications at any slope, optimized for use on 8:12 roof slopes.

Performance Features that Make a Difference
