Mechanically Attached Smooth TPO

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.
