©MBCI Rib heights vary slightly according to manufacturer.
This PBR type panel is recommended for commercial and agricultural applications.
- Support purlins should be spaced at 60" O/C (On Center). Size, orientation and installation method of purlins are determined by rafter spacing.
- Mastic sealer should be used at Anti-Siphon Rib (seams) if pitch is less than 1/2:12 with lap tek screws @ 20"± O/C {Note: some manufacturers do not have the "anti-siphon" option.}
- Mastic should be used at all end laps
- Foam bird closures are recommended at eave, pitch transition and ridge. Mesh (vented) closures may be used at ridge if desired
- Insulating underlayment may be needed, depending on intended use of structure. Almost always a good idea.
- the left (lap) rib must be over the right (bearing) rib
- Panels should be attached to purlins in the minor flat at the left major rib.
- Flats should be double screwed at eave
- Panels should always extend at least 1 1/2" beyond eave trim ; up to 8" if no gutter is to be used.

This is the proper way to "side-lap" a PBR panel

Reverse lap results in the same problem as using a non bearing leg panel

Gutter
©CMBC
In my opinion, this gutter is too gaudy for residential use, but really looks good on a commercial building. custom residential gutter can be designed and fabricated.
Gutter is attached by screws through the flat of the panels into the 3/4" lip of the gutter @ 12" O/C. Face of gutter is held straight by gutter-straps @ 36" O/C attached to panel ribs and 1" lip of gutter with screws.
Downspouts are then attached to the gutter. Gutter is marked (see sketch below) using a plastic (less likely to scratch finish) speed square to match size of downspout, and tabs are made for downspout attachment.

Rake (Gable) Trim
Top of rake trim is attached to flat of panel at 1"lip with screws @ 15" O/C and sealed with mastic. Face is attached at 1 3/4" lip with screws at a maximum spacing of 36" O/C.
Altough most manufactures can provide corners to join the rake trim to the gutter, they seldom fit well. It is easier to make corners than to use the prefabricated ones, and usually looks better.
