Comments:
Hi Val,
Jack Rench of Rapid Roof Systems asked me to forward this fire classification information to
you in regards to the Sherwood Inn.
I've sent 3 pages from our UL fire ratings. The first page is meant to show the information on
Duro-Last. The 2nd and 3' pages contain the Class B listings with the appropriate listings
circled. Essentially, over a wood deck 1 ply of Elk Versashield Underlayment or Elk Versashield
FB2S can be used as a slip sheet to attain a Class B rating. This assembly is good up to a 2"
per 12" roof slope.
Please note that Elk Versashield Underlayment and Elk Versashield FB2S are identical
products but are labeled differently.
Please feel.free to call me if I can be of assistance.
Thank You,
Kevin Kelley
