Wind Uplift

Structural Ipe tiles installed on a pedestal system essentially rely on gravity, tight spacing between the tiles and tight containment around the perimeter to keep the tiles in place without movement. The open joint space between the slats on the tiles allows wind to flow above, below and around the deck surface, which also tends to reduce uplift forces somewhat.

Since no specific standard exists regarding wind uplift of wood tiles installed on a pedestal system, Architrex engaged the Florida International University Hurricane Research Center to devise a test program to determine the wind speed at which uplift of Architrex 24″ x 24″ structural Ipe tiles would occur under various conditions. Variables incorporated in the test program included:

  • wind angles
  • pedestal heights and type
  • parapet wall height
  • paver layout
  • locking devices along the parapet walls

For each configuration, the wind speed was increased in 10 mph increments until either blow off occurred or the maximum wind speed of the Wall of Wind facility (approximately 150 mph) was reached.

Whilst the full Wall of Wind test report should be consulted for details of both the test procedure and results obtained for each set of variables, it was found that the wind speed at which blow off of Architrex 24” x 24” structural Ipe wood tiles installed on fixed height pedestals at 0° wind angle and with a 12″ parapet was 130 mph.  Note that no washer and screw assembly or any other fixing devices were used to hold down the tiles onto the pedestal heads in the tests conducted.
