Fleece-Backed SBS Base Sheet

Polyglass U.S.A., Inc., launches Modifleece, a revolutionary fleece-backed Styrene-Butadiene-Styrene (SBS) modified bitumen roofing membrane base sheet. Designed for the use in multi-ply low-slope roofing systems, Modifleece sets a new standard in roofing technology, offering unparalleled performance and versatility. 

Through an innovative laminating process, Modifleece integrates a specially formulated dual compound into the polyester fabric, creating a seamless bond between the two components. The self-adhered side laps are safeguarded by a protective release film, which is removed during application to reveal the aggressive self-adhered SBS compound, ensuring watertight seams. 

Key features and benefits of Modifleece include:

• Versatility: Suitable for application directly over irregular or semi-rough substrates, including Lightweight Concrete (LWC), and as a recover option over existing modified bitumen roofing systems.
• Durable waterproofing: Modifleece serves as a strong and durable waterproofing substrate for additional roofing membrane plies, ensuring long-lasting protection.
• Wind uplift resistance: The tough polyester-reinforces bottom surface fabric provides a robust foam adhesive bond, offering superior wind uplift resistance.
• Quick dry-in system: An adhered non-penetrating system eliminates the need for fasteners, providing a quick dry-in solution.
• Labor savings: The non-penetrating system saves valuable install time when compared to fastened base sheet systems, particularly in high wind areas.
• Cost-effective recovery: Ideal for occupied buildings, Modifleece offers a cost-effective and efficient recover option, making it a preferred choice for roofing projects.
• Safe and clean: Odorless, no mess, flame-free when used with self-adhered piles.
• Easy Installation: The self-adhered side laps feature an easy installation process, ensuring an immediate watertight seal.
