💡 Why install a ventilation spacer sheet under synthetic roofing materials
Installing a gap mat provides immediate breathing room that lowers surface temps fast
The nylon mesh traps moving air near the underside to block mold growth and stop membrane peeling
Handy spacing keeps your structure dry through wet seasons and cuts HVAC workload during peak summer heat
