A common misconception among Project Managers is that all “plastic” behaves the same under the weight of snow. This assumption leads to catastrophic failures when using standard 6-mil polyethylene sheets or woven blue tarps.
The Physics of Failure
Blue tarps are mechanically fastened at grommets. When snow accumulates, the load concentrates at these weak points, causing tearing. furthermore, tarps sag. This “ponding” effect creates pockets where ice forms, increasing weight until the tarp collapses into the building.
The Scaffwrappers Advantage
Scaffwrappers exclusively uses premium, virgin resin 12-mil shrinkwrap for roof applications.
- The Surface Tension: Because we heat-shrink the material “drum-tight,” we reduce the friction coefficient. Snow is more likely to slide off rather than accumulate.
- Uniform Load Distribution: Our installation process involves continuous strapping and heat-welding. There are no grommets to tear out. The load is distributed evenly across the entire truss system.
- 100% Containment: In the event of a heavy blizzard, our wrap does not flap or shatter. It is designed to withstand significant static pressures that would shred a consumer-grade tarp.
Don’t gamble your job site on a product designed for a backyard barbecue. Choose industrial-grade protection.
