and at the specified spacing. Reference the project’s installation drawings for the specified fasteners
and spacing.
For typical applications the panels are attached to the framing members with clips and screws
concealed within the panel joint. In some cases the design loads will require backside attachment of the
panels to the framing members in addition to the clips. At wall corners, framed openings and wall
termination, the edges of the panels are attached to the framing member with thru-panel screws. Do
not overdrive fasteners. Overdriving can cause the fastener threads to strip, sealing washer damage
and dimpling of the panel or flashing surface. The panel clip attachment screws must be driven until the
panel face is secure against the framing member, but must not be overdriven to cause excessive
crushing of the foam core and distortion of the metal panel edge. Distorting the panel edge will cause
difficult panel joint assembly and may cause visible rippling of the panel’s exterior face and excessive
joint gaps.

Remove any and all strippable films either prior to or directly following installation. Take measures to
avoid exposure of the film to direct sunlight for more than 24 hours.

UTTING
The panels are easily cut with circular saws or reciprocating saws using proper metal cutting blades. If
the saw cannot cut through the entire panel thickness, or if shears or nibblers are used, cut each panel
face and use a knife or handsaw to cut through the remaining foam core. Be sure to properly support
the panel during the cutting operation to prevent delamination of the face from the core or buckling of
the panel. When necessary, pad the saw’s shoe plate and guides so they do not scuff or scratch the
panel surfaces. Abrasive saws are not acceptable for cutting panels or flashing. Flashing is cut with
quality shears to provide a precise, undamaged cut.
A
PPEARANCE
Always cushion the panel surfaces from direct contact with temporary supports of lifting slings and
clamps, etc. To prevent bending or crushing damage, ensure that the panels are uniformly supported at
adequate spacing. Do not handle the panels in a manner that can cause buckling of the faces, or
separation of the faces from the core.
Insulated panels have wide, virtually flat surfaces. Wide, flat metal surfaces are subject to
uncontrollable oil canning. Many factors are causes for oil canning and no manufacturer can
realistically assure the total elimination of the phenomenon. Therefore, uncontrollable oil canning is
not a cause for rejection.
However rippling and wrinkling caused by improper handling, overdriving clip fasteners or
misalignment and deflection of the wall framing members can result in objectionable appearance and
must be avoided.
