Securock® UltraLight coated glass-mat roof board is a lightweight roof board engineered for low-slope commercial roofing systems. It combines a specially treated core with a coated glass-mat facer to deliver resistance to fire, mold and moisture while improving handling and installation performance.
Key features:
- Coated mat designed for adhered applications with UltraLight core — strong bond and low surface absorption.
- Strong bond and low absorption in cold-applied adhesive applications.
- Lightweight core: up to 18% lighter than competitive products (applies to 1/2" and 5/8" thicknesses only).
- Moisture- and mold-resistant core and facer.
- Provides protection to the roof system from hail and foot traffic.
- Fire-resistant: suitable for use as a fire barrier and thermal barrier.
- High mat-to-core tensile bond strength reduces likelihood of facer delamination during cutting.
- Tight, high-quality mat reduces fiber release and facilitates handling and cutting compared with competitive products.
