Regular or Hi-Flow: Two Protection Options
Grizzly Regular Panels
Regular panels are designed to block fine debris, such as shingle grit and small leaves, while maintaining strong water collection.
Grizzly Hi-Flow Panels
Hi-Flow panels are designed with larger openings to handle higher water volumes while still blocking most debris.
Grizzly Gutter Guard panels and accessories are WUI Fire Class A compliant, which is the highest fire-resistance rating. They’re approved for use in wildfire-prone areas and meet current ASTM code requirements.
This means they’ve passed the required fire tests for flame spread and ember exposure. They won’t contribute to fire spread on the roof or at the gutter line — exactly what inspectors and insurers look for in WUI zones.
