Commerce Township, MI used IMPERMEABLE covers with FOAM Insulation.

These photos were taken in the Spring of 2011 in Commerce Township, Michigan. You are seeing the turf as it appeared immediately following its uncovering. GreenJacket^® IMPERMEABLE covers & FOAM Insulation protected the greens from ice damage, crown hydration, desiccation, and help to keep the turf dormant during those freeze-thaw-freeze cycles, resulting in healthy green turf in the Spring.
