   We've used them in several houses recently. So far, no problems. As to how they compare to TJM, they can only span as far as an equivalent sized 2x. But they are somewhat less expensive than TJM and nice and straight.

   I've never used these, but doubt there is anything wrong with them. Like any floor system, make sure you don't push the span limits of them, or you'll have a springy floor.

   I doubt you'll have any serious problems with the 2X3s, as you mentioned. I think they're an MSR grade of SPF.

   *I became a Nascor wall panel dealer about 9 years ago before they started manufacturing their I-Joist. I was one of the first in Pa to sell the I-Joist and have had much success. You mentioned that they do not span more than dimensional lumber. Nascor products are ment to be transparent in conventional construction. All products are dimensionaly the same so trades, architects and builders do not have to change existing blueprints. With the I-joist normal hangers can be used. The EPA walls are the same. 2x6 top and bottom plate, second plate field applied. Nascor's new wall panel NASCOR III incorporates the same I-joist, and replaces 2x6 and 2x8 studs with the I-joist. This allows for 20 foot tall panels. All the builders I deal with and their framers are very happy with the I-joist and wall panels. Hope this helps...John GiulianiNascor building Systems of Pa.

   I've been quoted a very good price and NASCOR floor joists. These are an engineered product, which consists of two 2x3's on edge as flanges, with an OSB web in between.

   My concern is that over time the 2x3's will dry out and twist / split etc.

   Just wondering if anyone has any experience with this product, and in particular how you would compare it in quality with TJI's from MacMillen B. (sp).
