Installing smooth TPO with fasteners in a mechanically attached system offers several benefits, including:
Up to 50% faster installation compared to fully adhered smooth membrane installations
Reliability and cost effectiveness
Familiarity with the industry as the most common installation method in single-ply membranes
Consistent installation in a wide variety of temperatures
No sprayers or additional capital investments
A great option for occupied buildings, as there is no odor from adhesives
While fully adhered systems have better wind uplift ratings, a mechanically attached system’s ratings can be increased by modifying the fastening pattern from 12" on center to 6" on center.
Be sure to refer to the BMI Drill-Tec™ Fastening Guide to choose the correct fasteners and plates for your application.
