Ventloc’s patented venting edge enables the rapid transfer of over paver to under paver pressures. The transfer of pressures through Ventloc’s vented edge has been tested and proven to provide the best lightweight paver wind uplift resistance in the industry.
Ventloc® was tested at Intertek ATI incorporating three different conditions - no parapet, 12” parapet, and 24” parapet – with wind speeds up to 130 mph. In all three conditions, no movement was observed.
Pressures were recorded at four different locations – top, bottom and both ends. Ventloc’s equalization was maintained at a near zero value from the top surface to the underneath side of the paver, clearly demonstrating that the vents are transferring pressures. Refer to Ventloc® Test Report 11.4.15. Ventloc’s ability to equalize pressures, along with its true interlocking design, provides a much more wind resistant installation than pavers without vents.
