Core 4 Technology
Flexible Bendable Pliable
StormMaster® shingles with FlexCore bend and ex when others
crack and tear. Their elasticity is what makes them stronger in two ways:
BETTER TEAR STRENGTH: Because these shingles can bend and ex, they exceed
the industry’s standard tear strength requirement by 50 percent. Even in cold weather
installation, they are more likely to withstand tearing and cracking that can lead to
blow-os, leaks, and compromised long-term roof stability.
FLATTER INSTALLATION: Shingles that don’t lay at won’t properly seal during
installation. FlexCore technology makes shingles more pliable, which means they lay atter,
seal properly, and provide greater protection for your home.
