PAC Flat Seam Panels (FSP-12) are designed for soffit applications where a flush or flat appearance is desired. A tongue and groove style interlock and concealed fastening system improves the flush appearance while providing good strength. Panels are formed to length to minimize field cutting. Maximum recommended panel length is 25’ with a minimum panel length of 4’.and are available in a tradition 12” width.

Stiffening Beads

The Flat Seam Panels are available with two (optional) stiffening beads. Stiffening beads are recommended for longer panel lengths.


All flashing and trim shall be fabricated by manufacturer or qualified fabricator. Flashing shall be produced from PAC-CLAD aluminum or steel flat sheets. A 35-year non-prorated finish warranty can be supplied covering finish performance. Vinyl masking is recommended on all fabrication applications where extra handling is expected.


When used in a soffit or windscreen application, panels must be fastened (stitched) through side joints. Consult a local architect/engineer for requirements of local codes and conditions.
