Cedar On A Ceiling

Ray Member


I will be installing red cedar on a ceiling 16' X 32' that has 2" of soft sound insulation that is attached to the bottom side on a metal grid system. The boards are 16' long and the sizes are 3/4" X 3/4", 1 1/2" X 1 1/2, and 1 1/2" X 2 1/2" with a 1 1/2" spacing that makes a random but repeating pattern. With no expose fasteners.
I tried rabbiting the top side of lumber 3/8 X 3/8 and use some power grab adhesive that would receive a same size stick but 8" long, with a screw in the middle of it. The pull out test was iffy.
I would like to find metal clips that would work.
Anybody suggestions?
They rejected holes and plugs but could have to live them.

I would call Kip Porter at Star Hanger, Man is a genius in Fastening architectural work

Would it be possible to fasten some 1/2" plywood to the ceiling, and then it may be easier to fasten the cedar to the plywood?

16 sheets of plywood could be an inexpensive cure. Does any of this material need to be fire-rated?

That is something I haven't considered. The 2" insulation is attached to the grid by
clips. I will ask if the clips would work with
with plywood. Yes this needs to be fire rated blocking.

Use fire rated Ply wood adn cut strips where needed, no need to cover entire cieling it is blocking,, or go straight to studs, it is cedar floor plank right ?

This is lumber of 3 different sizes with spacing between each board. The largest is 1 1/2 X 2 1/2 some are laid flat and some on edge. The 2 1/2" plus the 2" would require a 5" screw. Plywood strips or 2 X 4 blocking might work. Cut sheets attached.
Plugs and screws will be a hard sell.

The simplest easiest way would be to fasten 1/2" plywood or 1/2" osb to the whole ceiling.

Then you can toe screw any of those pieces of wood to the ply.

I would not consider doing this job on a contract basis. T&M only or they can find somebody else.

This is for a ceiling, right? There are no studs in a ceiling.

+1 on screwing ply to the ceiling; use self tapping tek screws w/wafer heads. Since the ceiling is suspended I'd check with the contractor/architect/engineer to be sure the system can carry the weight of fire rated ply.
Then paint the background, adhesive & trim screws to apply.

Mark makes good points about painting the background, for uniformity and possibly for contrast, and determining if the suspended ceiling infrastructure will hold the weight of the plywood. You should also consider the combined weight of the plywood and the cedar.

If the weight capacity allows you to use the plywood, one thing that you might try is to channel or rabbet the cedar, much as you tried before, except now you can pin the glue strips to the plywood.

You could fasten these glue strips prior to securing the plywood to the ceiling, allowing you to register the spacing you need for the cedar pattern with the glue strips, making the installation of the cedar E-Z.

Not sure of the finish requirements, but with glue strips in place, you may be able to pin the cedar in place through the face with a 23 gauge Grex pin nailer, which would almost defy detection from the floor, or through the sides of the cedar with a nail gun if the spacing between the cedar does not allow a full-on view of the cedar sides.

Good luck.

  • Posts with the intent of soliciting answers to surveys are not appropriate. Contact WOODWEB for more information on initiating a survey.
  • Excessive forum participation by an individual upsets the balance of a healthy forum atmosphere. Individuals who excessively post responses containing marginal content will be considered repeat forum abusers.

    WOODWEB's forums are a highly regarded resource for professional woodworkers. Messages and responses that are crafted in a professional and civil manner strengthen this resource. Messages that do not reflect a professional tone reduce the value of our forums.

    Messages are inappropriate when their content: is deemed libelous in nature or is based on rumor, fails to meet basic standards of decorum, contains blatant advertising or inappropriate emphasis on self promotion (return to top).

    Libel:   Posts which defame an individual or organization, or employ a tone which can be viewed as malicious in nature. Words, pictures, or cartoons which expose a person or organization to public hatred, shame, disgrace, or ridicule, or induce an ill opinion of a person or organization, are libelous.

    Improper Decorum:   Posts which are profane, inciting, disrespectful or uncivil in tone, or maliciously worded. This also includes the venting of unsubstantiated opinions. Such messages do little to illuminate a given topic, and often have the opposite effect. Constructive criticism is acceptable (return to top).

    Advertising:   The purpose of WOODWEB Forums is to provide answers, not an advertising venue. Companies participating in a Forum discussion should provide specific answers to posted questions. WOODWEB suggests that businesses include an appropriately crafted signature in order to identify their company. A well meaning post that seems to be on-topic but contains a product reference may do your business more harm than good in the Forum environment. Forum users may perceive your references to specific products as unsolicited advertising (spam) and consciously avoid your web site or services. A well-crafted signature is an appropriate way to advertise your services that will not offend potential customers. Signatures should be limited to 4-6 lines, and may contain information that identifies the type of business you're in, your URL and email address (return to top).

    Repeated Forum Abuse: Forum participants who repeatedly fail to follow WOODWEB's Forum Guidelines may encounter difficulty when attempting to post messages.

    There are often situations when the original message asks for opinions: "What is the best widget for my type of shop?". To a certain extent, the person posting the message is responsible for including specific questions within the message. An open ended question (like the one above) invites responses that may read as sales pitches. WOODWEB suggests that companies responding to such a question provide detailed and substantive replies rather than responses that read as a one-sided product promotion. It has been WOODWEB's experience that substantive responses are held in higher regard by our readers (return to top).

    The staff of WOODWEB assume no responsibility for the accuracy, content, or outcome of any posting transmitted at WOODWEB's Message Boards.
