Notes
i Based on use of spruce, pine, or fir wood species
ii Studs to be minimum 16 gauge steel with 33 ksi yield stress
iii Hollow core CMU to be filled with minimum 1500 psi strength grout
iv Grout to have a minimum compressive strength of 2000 psi
v Hollow or solid clay brick to conform with ASTM C62 standard
vi Concrete to have a minimum compressive strength of 3000 psi
vii Fastener/Anchor recommendations based on maximum wind load of 78 psf
viii Fastener/Anchors to be installed a minimum of 3/8" from track edges at a maximum spacing of 18" apart
ix It is the responsibility of the engineer of record to verify the structural integrity of the backing wall based on the load imposed by the system panels and other applicable material, live, seismic, snow and wind loading conditions.
x Alternative fastener/anchors recommendations available from supplier upon request.
xi Substitutions of recommended fastener/anchors should only be made after structural analysis by engineer of record.
