Based on RAS-127 and F.L. #7849.25, the following are our recommended tile attachment
requirements:
Attachment Requirements:
Tile System: Moment Based (Boral Saxony 900 Flat Roof Tile)
Aerodynamic Multiplier: 0.315 ft3 (Direct Deck Attachment)
Restoring moment due to gravity: Mg = 7.17 ft. lb (6:12 slope)
Attachment resistance expressed as a moment: Me = 83 ft-lb
Single Medium Patty Foam Adhesive Set (24 g)
Zone 1 Field: Mrt = (54.0*0.315) — 7.17 ft. lb = 9.9 ft. lb. < 83 ft. lb = PASS
Zone 2e Perimeter Eave: Mrze = (74.6*0.315) — 7.17 ft. lb =16.3 ft. lb. < 83 ft. lb = PASS
Zone 2r Perimeter Ridge: Mrz, _ (74.6*0.315) — 7.17 ft. lb = 16.3 ft. lb. < 83 ft. lb = PASS
Zone 3 Corners: Mr3 = (74.6*0.315) — 7.17 ft. lb = 16.3 ft. lb. < 83 ft. lb = PASS
System is acceptable as approved with ICP Adhesives Polyset AH-160
(Single Medium Paddy placement of 24 grams)
Notes: All work shall be in compliance with the local building code product control notice of
acceptance and manufacturer specifications and the Florida Building Code 2020 edition.
Wind load calculations based on ASCE 7-16 and information provided by client.
All work shall be inspected by our field engineer or city inspector to verify compliance
with specifications.
