Enhanced Fiber Structure Design for Strong Mechanical Support

Many synthetic roof underlayments on the market incorporate high-density fiber grids, such as HDPE mesh or

high-strength PP fibers, as reinforcement materials. This significantly improves their tensile and tear resistance

compared to traditional asphalt felt. Tests show that some synthetic underlayments achieve tensile strengths of

several hundred pounds (lbf) and tear resistance of 20-50 lbf, providing solid structural support for roofs.

Superior Damage Resistance, Reducing Construction Risks

During roof installation, underlayments are often exposed to scratches from tools, nail punctures, foot traffic, and

friction from material handling. The high-molecular synthetic membrane structure of MOUNTAIN BIGFOOT BARRIER

prevents small damages from expanding into large tears, greatly reducing the risk of damage during construction

and enhancing installation safety.

Stable Performance in Extreme Conditions for Long-Lasting Protection

Ordinary roofing materials struggle to withstand extreme weather conditions such as strong winds and hurricanes,

as well as the structural stress from frequent maintenance work. However, MOUNTAIN BIGFOOT BARRIER maintains

its integrity under high tension and shear forces, significantly improving the overall stability of the roofing system

and providing superior long-term protection.

With its outstanding tear resistance and high-strength structure, MOUNTAIN BIGFOOT BARRIER is the ideal choice

for enhancing roof durability and safety.
