    I'm quoting a double sided directory aprx 4'x6' which has a 1" PVC background specified with 8"x66" 1/4" PVC tenant panels specified. Not what I would choose but that's the spec. So I'm thinking about the best way to fasten the tenant panels to make them removable. Right now we're thinking round head thru bolts with acorns on the second side. Another option was nut serts but I've not sure about using them with PVC.. Any other solutions that have worked? Thanks

    Boy, that size panel is gonna need at least 8-10 attachments to keep it from warping too much unless they get laid flat against the background and have a couple double sided tape tabs to help hold them flat. I like your first idea better than the inserts. At least then the pressure of the through bolts will hold everything together and act as a hedge against any warping.

    Is this an outdoor sign? The one I service at our hospital is a tad larger than yours, and has 8"x64" ACM panels that sit flat against the sign face with 3 round head screws.

    Your key word of the day is SPEC. This word is used when architects dont know what the hell they are doing and getting all up in our business. I would spec this out and make notes about it NOT being the most effective was to make a directory and then offer them a more sensible solution. I would much rather do a double sided aluminum sign 1" thick framing wrapped with .063 aluminum for rigidity, then your tenant panels could be done with VHB and use .063 panels for tenants

    That thickness of PVC is overkill (another thing architects do) its too damn heavy for a directory and is totally uncalled for. Stand your ground, make your points and send the quote back. I have done it several times and it has paid off.

    I may switch to ACM for the tenant panels, but have to stick with the 1" pvc background. So I guess my best option for fastening the panels is thru bolts.

    I'd go nutserts...
    and use acrylic or ACM for the panels. PVC is gonna warp to hell and look bad.

    We use threaded metal inserts in the background and ACM panels for the tenant names. When you drill your screw holes in the ACM panels make them a bit wider to allow for thermal expansion. Use a screw cap or a washer to cover the enlarged hole.
