UV Stability and Weather Resistance

 

MOUNTAIN BIGFOOT BARRIER is formulated with UV stabilizers and thermal stabilizers, effectively resisting intense sunlight,

repeated freeze-thaw cycles, and ozone degradation. While traditional asphalt felt often cracks under sun exposure, synthetic

underlayment remains stable for months (depending on the brand) without deterioration.

 

Stability in Extreme Conditions

 

 

Comprehensive climate testing shows that MOUNTAIN BIGFOOT BARRIER maintains its physical integrity within extreme

temperature ranges—from -40°C to over 90°C—without noticeable shrinkage, deformation, or aging, ensuring long-term

durability.

 

Resistance to Chemicals and Biological Growth

 

Its polymer membrane offers exceptional resistance to chemical corrosion from acids, alkalis, and salt spray. It also prevents

the growth of mold, moss, and algae, remaining intact and effective even in industrial or coastal environments with high

humidity and pollution.
