Core 4 Technology
During its lifetime, your roof experiences thermal shock, or wide
variations in heat and cold. StormMaster® shingles are built to
mitigate the aects of EXPANSION AND CONTRACTION due to
temperature changes.
ThermalCore also leads to BETTER GRANULE ADHESION. Even as
the shingles expand and contract, they are less prone to shedding
granules. This quality is important because shingle granules play
a critical role in protecting your roof from the elements. Premature
granule loss can lead to accelerated aging, asphalt exposure, and
roof deterioration.
• Shingles with ThermalCore have 18 PERCENT BETTER
granule adhesion than standard asphalt shingles.
