PolyCore technology is what makes shingles with Core4 stronger and longer-lasting than
other leading shingle brands.
StormMaster® shingles with Core4 are made from enhanced virgin polymers, which means
the asphalt core is scientically engineered to perform better with increased consistency
and reduced variability.
In comparison, shingles containing recycled polymers are made of imperfect materials that
can adversely aect the life span of your roof.
BECAUSE OF POLYCORE TECHNOLOGY, CORE4 SHINGLES:
• Protect and extend the life of your roof.
• Perform better than standard asphalt technology.
