What is the generic name for tectum? We have been using “Acoustical Cementitious Wood Fiber Panels” and the architects are complaining that it is too long.
There’s no need to use a generic name because there’s no one else that makes the product! At least, that was the case a few years ago when I was challenged in a public job for using a proprietary product. Does anyone know of an equal to this material?
Found a series of products called “Fibroplank” made by the Martin Corporation-
www.martinfireproofing.com
Shown as equivalent to Tectum, by name, in MasterSpec 03511
Even if the product is sole source, I don’t think it’s good practice to use proprietary names on drawings. I call tectum “wood fiber panels”.
We too have specified Martin Acoustical Products as another manufacturer in addition to Tectum; their product was called AcoustiPlank.
In what section do you specify Tectum?
Depends how I use them. If for acoustical purposes, I’ve used Section 09810. If just for suspended ceiling panels in a typical suspended ceiling grid, Section 09510.
I concur that it’s bad practice to use a trade name on drawings. . . It’s been years since I specified Tectum, but “cementitious wood fiber acoustical panel” sounds reasonable. I don’t understand the complaint with respect to length. Don’t your drawings have an abbreviation list and can’t you go from there with “CWFAC”?
Why not just call them “acoustical panels” on the drawings and let the specifications specify what they are? Is that a radical idea? We use abbreviations (AWP is an acoustical wall panel, for example, and if we have more than 1, it’s AWP-1 or AWP-2) and the abbreviation is then used in the spec to identify what is meant by the specification - which can be a paragraph! No size restriction in the specs like there is on the drawings. Drawings have enough stuff on them and usually very little room for words. Isn’t that one of the reasons why we have specifications?
Yep. Come to think of it, I’ve done it Lynn’s way too. And my the way, my “CWFAC” abbreviation above should have been “CWFAP.”
Thank you Lynn - Yours is the best idea I’ve heard on the subject. It would definately be my choice and I have done it this way for a number of products that otherwise defy description. If we ever took this long to decide on what to call something we’d never get anything done. Thanks again for “cutting to the chase”.
CWFAP = see wa fap?
It literally runs off the tongue!
Make sure to specify the type of Scotch tape to use to attach the Tectum panels to the Sheetrock.
So, you followers of abbreviations, what would you call the material when used as a roof deck?
CWFARD?
In keeping with the simple approach, I’d probably use RD-n, where “n” is a number, and identify it in the spec as “cementitious wood fiber acoustical roof deck”. That allows other roof decks on the project. Remember “K.I.S.S.” If an abbreviation is as long as what you’re abbreviating (and I’ve seen some like that), you’ve missed the idea of abbreviation.
It appears my sarcasm was missed.
With word processing and computer aided drafting, abbreviations are not used in my office.
No, it wasn’t - I just chose to ignore it.
How about Cementitious Wood Acoustic Panels (CWAP)
It’s Friday–we need a little levity here
With apologies to David Sedaris,
Me Talk Better Sarcasm One Day
Dave, too bad they aren’t Cementitious Resin Acoustic Panels.
I like Lynn’s description. If I had my way, I wouldn’t use them because I think there are better products out there.
Where do you suppose “Tectum” will be located in Masterformat '04?
