Jan 20, 2006 · In a couple of weeks, I’m going to have to make a decision on our current project (new construction) to possibly substitute the specified 2×12 rafters with 12″ 560 series TJI rafters. Since the rest of the house (floor frames, girders, etc), except for the 2×6 and 2×4 fir stud walls (interior and exterior), is made up of structural ...

Dec 30, 2008 · I have done a lot of framing over the years, and have never used floor trusses. Now, TJI's, that is a different story. I would build with them in a heartbeat. My boss, built his house with 12" tji instead of 9.5 and loves the stiffness of the floor. In otherwords, designed for the 9.5 and substituted the 12".

May 28, 1999 · *I have used TJI's in the past and have really enjoyed using them, upfront they are about 10-15% more than 2x lumber, but they do go in alot quicker using 19.3" centers. And most of all you cant beat the consistency of engineered lumber, TJI's make for a beautiful subfloor.

Jan 18, 1999 · Use hangers when attaching at 90 degrees. For the TJI that the hanger is hung on, fill the web cavity with a piece of plywood that will sit flush with the flange. Throw a generous bead of adhesive into the hanger before you drop the TJI to be hung into it. Anti-squeek medicine. There are some specifics when working with TJI's.

Jun 12, 1999 · Help, please, from folks who have used TJI's in floors. My builder has never used (and I suspect he is reluctant to start using). He says the trunk for the HVAC ducts would have to go under the TJI's, and that it has to go down the center of the basement. This would make the basement ceiling very low unless we take the foundation blocks up to 10'.

Jun 18, 2006 · The architect had specified 9 1/2″ TJI to span the addition (it’s approx. 37′ long and 25′ wide. Joists are running parallel to the 37′ run). Anyway, my question is, in the plans, they spec out TJI, but in the “first page” of the architect’s stuff, it says they can use I-Joist or Trus-Joist.

Mar 3, 2008 · For new construction, the plan includes an outside foundation wall that is 18 feet x 18 feet (9 foot foundation wall for basement). The joists that span that 18 foot wide length (to create the 1st floor) are specified as 9′-6″ TJi members. They run the entire 18 foot length without any center beam with lolly collumn.

Apr 16, 2006 · Poor planning on my part has led to a problem I was trying to avoid. Second floor bathroom, floor framed with 11-7/8″ deep TJI I-joists. We are trying to install a one-piece acrylic shower unit and ran into a problem – the drain for the shower is right over the top of (but not quite centered on) one of the joists.
