So what is Core4™ and
what does it mean for you?
Core4™ is the most innovative development in
asphalt shingle manufacturing and consists of
these four features:
Shingles are the rst layer of a home’s defense,
protecting us against extreme weather that can be
dangerous to the people and things we hold dear.
When you choose Atlas shingles with Core4™
Technology, you can be sure that you are sheltering
your family beneath some of the most durable
shingles in the industry.
PolyCore™ Technology is what makes shingles with
Core4™ stronger and longer-lasting than other
leading shingle brands.
StormMaster® Slate shingles with Core4™ are
made from enhanced virgin polymers, which
means the asphalt core is scientically engineered
to perform better with increased consistency and
reduced variability.
In comparison, shingles containing recycled polymers
are made of imperfect materials that can adversely
aect the life span of your roof.
Because of PolyCore,™ Core4™ shingles:
• Protect and extend the life of your roof.
• Perform better than standard asphalt technology.
