Metal Ceiling Layout and Install Tips

[dsl_mech]

Trying to narrow down a layout and panel size for my metal ceiling. Inside dimensions of building are 39' width with scissor trusses with a 15'-7" bottom cord length. Trusses are spaced 24".

-How important is it that the panels overlap on a truss?
-Seems 6" is a common overlap when used on a exterior. Can I get away with less overlap when used on the interior?
-Is it acceptable to have the seems line up?
-I am going to meet the peak in the middle of a sheet. My plan is to bend the sheet at the peak and carry on down the other side. Does this seem like a good idea? The ceiling is sloped 1.5/12

I am leaking towards going with 4 rows of 10' panel as this seems it will line up with the trusses nicely and smaller panels will be easier for me to work with. Other option is going with two rows of 12' and one row of 16'. My hope is that the 1' extra in both scenarios can be used up as my overlap and avoid having to do much cutting.

Thanks for any advice.

You want your overlap to not be "seen" as you walk in the building. So plan on placing the first row accordingly.

If you are working by yourself, get a drywall lift.

I'd strap (1x4) across the truss bottom @24" centers and run into a J channel at both ends "running" the metal from the wall to the peak.
Going the "long way" is more work and you'll still need the channels.
It could be possible to bend the panel parallel with the ribs at the peak but you'll need a heavyweight break (not a typical siding guy break) and you'd have to do some careful measuring and maybe even start at the peak with the bent panel and work down.
Long parallel lines/panels running parallel with the peak are unforgiving to the eye and will require following a chalk line each "course".
Doing this yourself, you'll be surprised how much resistance the slightly bowed out insulation will give you and hitting the 1 1/2" target by yourself will be challenging to put it politely. These 1x4's will hold the insulation back and give you a nice wide target for the fasteners.
It's also a great wire chase for any lighting and fan's.

Other than maybe along the last row of sheets, there should be no cutting, save for attic access, don't forget about it.

Measure your sheets for the layout and order them to length. Your supplier will cut them off to the ordered length, it's not a big deal. If you order from Menards, you place the order by length in inches.
