insul-lam
Insul-Lam is used as a non-structural nail base
in either a one or two layer system.
in either a one or two layer system.
two-layer system – Begin by installing the
2x dimensional lumber dam around the
perimeter of the roof. The height of the dam
is determined by the depth of Insul-Lam being
installed. In residential applications, PBS
recommends the use of a vapor retarder with
either the one or two layer systems. You
will need to cut one 2’ x 4’ foam section
and enough 2’ x 8’ foam sections from your
shipment to ring the perimeter flush to your
lumber dam.

remaining 4’ x 8’ foam sheets.
top layer – Apply the nail base top layer
perpendicular to the foam layer so that joints
overlap. You will need to remove 1 1/2” of
foam along the edges of your perimeter course
so the OSB overlaps your lumber dam. Once
an Insul-Lam top sheet is in position, fasten the
assembly to the deck with Premier Panel Screws
following the spacing and frequency determined
by engineering. Penetrate the structural deck
to a depth of at least 1”. Along the perimeter
