1. Table values are based on the manufacturer’s published fastener properties. The methodology for reducing the fastener capacities to account for the insulation are based
on the NDS allowable lateral loads for fasteners as modified by AWC 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).
2. Maximum thickness of continuous insulation shall include any rain screen material, sheathing that does not serve as a nail base, and airspace between the cladding and the
continuous insulation, where present.
3. Each panel shall contain a minimum of three (3) fasteners and penetrate the concrete or masonry wall as identified above.
4. 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.
5. Fasteners shall have the following minimum head diameter: Masonry nails, 0.312"; Hilti fasteners, 0.322"; Tapcon fasteners, 0.325".
6. Tools used for driving pneumatic or powder actuated fasteners shall be adjusted to avoid over driving the fasteners and damaging the panel.
