SOFFIT APPLICATION continued
• Space nails 6" o.c. at panel edges and
12" o.c. at intermediate supports. Do
not use staples.
• When installing the Architectural
Collection vented sot, avoid cutting
through the vented areas. If it cannot
be avoided, take special precautions to
avoid damage to spokes within the vent.
• Avoid diagonal cuts through the vented
areas. If necessary all sot edges must
be supported or backed by solid framing.
• Use construction adhesive to attach
spokes within the cut area of the vent to
solid framing.
• Exhaust ducts shall terminate not less
than 3' in any direction from openings
in vented sot. Refer to your local code.
• The spokes within the vent may warp
slightly during acclimation to the local
environment. This condition is only
temporary and the spokes will straighten.
• In closed sot applications factory
manufactured Cut-To-Width sot is
approved.
• Field prepared Cut-To-Width sot
should comply with local building codes.
