(Existing exterior window wall, interior fit-out including new partition walls that terminate at window mullions). I had one that I used, thought it was an Illbruck product, but can't seem to find it in the product literature...don't know if the product is discontinued or if my brain is...

Perhaps your favorite product was reformulated and renamed?

That was it. Boy, was I confused. and, Lisa, thanks for that info, too. That explains some other things that confused me in this search...

Although each partition terminates at a mullion, that product almost fits the description on the drawings...I'll file that one away for future use. You just never know what you'll need. Thanks.

You may be thinking of Willseal, which I think used to be an Ilbruck product, but seems to be independent now. www.willsealusa.com Lynn Javoroski CSI CCS LEEDŽ AP SCIP Affiliate Senior Member Username: lynn_javoroski Post Number: 1026 Registered: 07-2002 Posted on Thursday, April 08, 2010 - 12:00 pm:    John, I think you're right and I'm glad to know the products are still out there. They do have a rather wide tape that may have been in the designer's mind, but it's definitely the wrong application here. (Commissioner) Gordon to the rescue...sorry, Bat Man.

I specify a product called "EPDM Type EE1 3000" Series by Williams Products, Inc. www.williamsproducts.net Paul Gerber Intermediate Member Username: paulgerber Post Number: 4 Registered: 04-2010 Posted on Wednesday, April 14, 2010 - 05:25 pm:    OK, bit of a silly question (maybe) but since I have never had the need for a product similar to this one, in which Section would you typically specify this? 09 21 16 Gypsum Board Assemblies? Man I have to get our office switched over to MF2004 soon...I had to look that up instead of saying 09250 Gypsum Board Systems. It appears the conversion has been much wider spread in the US than Canada. Most Project Manuals I receive (typically from clients as reference from past recent projects) have still been in MF95 format, but most information available online is in MF2004 format. But not hard to see why our office hasn't switched. I just recently got Office 2007 (used to have 2000) and Acrobat Pro 9.0 (was using *gasp* 5.0) so we aren't necessarily on the "bleeding edge" of technology...besides, it's only been 6 years since the new (?) MasterFormat system was released right? LMAO Ride it like you stole it!!!

I've yet to hear back from the designer, though, so I don't know if they will accept this solution from a mere spec writer. And welcoume, Paul!

Every time there is a mis-alignment in the field, it is the drywall sub that has to fix it. I just had about 150 windows with this same problem.
