The Stability Behind Core4® Shingles
ThermalCore® Technology — found in StormMaster® Shake shingles made with Core4® Polymer Modified Technology — mitigates the effects of thermal shock.
When an asphalt shingle gets hot in the sun, the asphalt expands and gets gooey. When the shingle gets cold, the asphalt contracts and gets brittle. The constant cycle of gooey and cold leads to granule loss, which can cause accelerating aging, asphalt exposure and roof deterioration.
However, with ThermalCore®, shingles have more stability and consistency during expansion and contraction. In fact, lab tests show that shingles with Core4® have 69% better granule adhesion compared to other standard asphalt shingles.
