Lumber Connection
Lumber spline – PBS panels are designed to accept kiln dried lumber set into a standard
1 1/2” recess along the bottom, top, corners and window openings of the panels. Simply cut the plates to length, apply a 3/8” bead of Premier Mastic between plys of the dimensional spline and nail dimensional splines together. Apply a 3/8” bead of Premier Mastic along the sides and center of the recess, set the lumber into the recesses and nail off through the skins with 8d nails 6” o.c. or according
to your shop drawings. The lumber should remain flush with the edges of OSB. If your lumber has swelled, it may be necessary to chamfer and trim the piece so it will fit properly. Always dry fit the dimensional lumber before applying Premier Mastic.
