1. Fastener lengths are the maximum length commonly available for a given diameter. Longer fasteners may be available from proprietary sources. See note 4.
2. Table values are based on NDS allowable lateral loads for fasteners as modified by APA TR12 for use with a gap parameter for gravity load only (i.e., fasteners sized to support
weight of cladding, while cantilevered from framing a distance equal to the foam sheathing thickness).
3. Each panel shall contain a minimum of four (4) fasteners. Two (2) of the fasteners must be installed into the stud and penetrate a minimum of 1" for wood studs or three (3) threads
beyond the backside of steel studs. The other two (2) fasteners are permitted to be fastened through the WSP and must protrude out of the backside of the WSP a minimum of ½".
Where nailable sheathing is not used or studs are greater than 16" o.c. and not greater than 24" o.c., Versetta Bridging must be used to transfer the loads back to the studs.
4. ‘n’ – Non-standard or proprietary fasteners may be available with the additional length required to meet the penetration requirements.
5. Where a substrate other than nailable sheathing is used, its thickness shall be added to the continuous insulation thickness for the purpose of determining the fastener size.
6. Table assumes ½” sheathing applied to framing. For other sheathings thicknesses, evaluate fasteners accordingly for minimum penetration into framing.

1. Listed wind speed is V
ult
, per ASCE 7-10, the maximum allowed wind speed condition for the fastening method shown.
2. Maximum allowable wind speeds are based on the average ultimate loads tested for each condition divided by 1.5.
3. ST – Each Versetta Stone
®
panel contains two (2) fasteners installed into studs (ST) and at least two (2) fasteners into WSP only.
4. NP – Not permitted.
5. Assumes a minimum
1

" into wood studs) and a minimum of
½” of screw protruding out of the backside of the WSP.
6. Pressure equalization factor in accordance with ASTM D5206, Procedure B equals 1.0.
