TRI Alliance - Webinar - TRI High Wind Design Tables/Tile Factors

This seminar we look at the new ASCE-7 -22 wind uplift tables for our concrete and clay roof tiles as it relates to tile proflies. For our installation guides, we have used a generic tile dimension that has the tile factor of 1.407 ft³  to be conservative and consistent through all the tables. Each tile size can create a unique tile factor that may allow for lower uplift resistance.  

The Tile Factor is determined from the following equation:

TF = b*L*La (ft³) where:

b = exposed width (ft)

L = roof tile length (ft)

La = 0.76*L

Or use the tile factor ratio that provides the ratio of the actual tile to the 1.407 (ft³) that some manufacturers have in their formal Product Approvals.

We will explore the benefits of product-specific designs.
