One of the most common misconceptions in the temporary enclosure industry is that all shrink wrap performs identically. Gauge selection is an engineering decision, not just a cost variable.
7-Mil Applications
7-mil shrink wrap is appropriate for interior containment projects, light-exposure temporary storage, and short-duration enclosures in mild-weather environments. It is not appropriate for open-air structural enclosures in hurricane or high-wind conditions.
12-Mil Applications
12-mil industrial shrink wrap is the standard for structural enclosures exposed to wind loads and extended duration projects. The added thickness dramatically improves tear resistance at heat-fused seams, which are the typical failure point under wind loading.
The Right Answer for Your Site
StormWrappers project managers conduct a site-specific exposure assessment before every project and recommend gauge accordingly. The material cost difference between 7-mil and 12-mil is minor relative to the cost of an enclosure failure.
