Ceiling Options for Clubhouse

[Welshman]

I need some ceiling ideas for our sportsmen's clubhouse. This is a project that the membership has been talking about for years, but we now maybe in a financial situation to get it done. The overall goal is to insulate the building to make it easier to heat and cool.

The building is 48' x 28' with roof trusses on 8' centers. We had talked about putting in structure to hang drywall or other material, but I suspect the trusses would not be able to handle the additional weight. The trusses are marked "32lbs. 96 o.c.", and I don't know what the 32lbs. represents. The only other option I can think of is a suspended ceiling, with insulation between the rafters.

Any thoughts and ideas will be appreciated.

Metal trusses or wood trusses? What was the building used for before, or is this a new build? A pic would help.

Not sure if you care how fancy it is, but I am hanging metal liner panels for the ceiling in my barn. Blow in insulation on top of it. The liner panels I will be using are white which helps add some brightness.

With 8 foot spans you would want to run some purlins to attach it to.

I've used metal roofing in white. Brightens things up. You should be able to span 8'. No paint, no sheetrock to fall apart. You could purchase 16' sections plus a couple inches for overlap. We put 27'pcs with 2 people no problem.

The "32 lbs, 98 OC" probably means rated for 32 lbs/sq ft load on the roof when spaced 98" or less. I'm a big fan of metal liner panel for minimal maintenance. Liner panel is less than 1 lb/sq ft. so load is no problem.

However nothing, including liner panel, is rated for span 8 feet. It should be supported every 4 feet. For your building you would probably want to run 2x4 perpendicular to the trusses at 4 foot spacing. Be sure to put a vapor barrier under the metal and then you can blow in as much insulation as you want above the ceiling.

Thanks for the replies.

They are wooden trusses. The building was built in '76 or so, to be a clubhouse, but at the time apparently, the members were not shooting in the winter, so keeping warm was not a priority.

Metal panels would be fine (I've recently helped a friend do his new shop with them and they look great), but I'm still concerned about the weight. Its taken so long to get a ceiling up, and I don't want it to come back down. It seems like there must be some formula or spec to determine what "hanging load" the trusses will handle.

I'm a huge fan of spray in closed cell insulation. It adheres to the metal and adds rigidity and sound insulation as well. Close cell does not invite moisture either. You can hang about any covering material you want over it.

Thanks for that. "98" was a typo - should be 96. I'm not clear on what you mean by liner panel.

Liner panel is just metal panels coated for interior use. Cheaper than siding or roofing panels.

generally the design of manufactured trusses take into account the span, spacing, live loads (wind/snow), and dead loads (weight of materials used to build trusses, roofing, sheathing, insulation, ductwork, and ceiling).......this is all plugged in and effects the design......if you can find the original shop drawings done this would be printed on it....you might find them in old records at the club or at the building department if a permit was taken out.......outside of that the only other way I know of to answer your question would be to have a structural engineer run the calculations based on the design of the truss.....Jack

Keep in mind metal panels come in different gauges, (thickness). Thinner means less weight.

Thank you.

Shooting? Archery? Air guns? If firearms, the metal ceiling may intensify the sound.

Thanks for that. There are no records at the club, but a permit was issued at the time, so maybe the county has the data. It seems like this info should be marked on the truss, but oh well... Does anyone know of an online calculator that would tell me what I need to know, without tracking down (and paying) an engineer?

Also, regarding ceiling material options: Years ago I've used a product for a couple of different applications that I used to call "fiber board". It came in 4' x 8' sheets. The material was like the material that they make the drop-in panels for suspended ceilings. Does anyone know what the proper name for this material is, because "fiber board" doesn't yield any good search results.

Thanks.

Celotex ?

There is a reason you see them no larger than 2 x 4 ft on ceiling tile. Now using them with the metal grid could be a option. Not my first choice but possible

 

[KennyG]

In my opinion, the weight of metal is so small you shouldn't be concerned at all.

Agree

Fiberboard roof substrate? Something like this: https://www.homedepot.com/p/Contine...48-in-Fiberboard-Roof-Panel-STR1281/202280452

It's lightweight, 22 lbs for a 32 square foot sheet.

I don't think it would make a good ceiling though, I suspect it would sag over time.

Especially if installed in a humid environment...

I have never seen fiberboard roof panels span a distance. Keep in mind humidity from the air soaking in over time and then a saggy ceiling.
