Is engineered lumber more "green" than solid sawn?
Anyone reading this website will be familiar with the green angle for engineered lumber, using wood more efficiently. And of course there are technical advantages to I-joists, especially for longer spans. However I feel some influence by Mr. Riversong to steer toward low-tech solutions. Solid sawn lumber is certainly lower tech, and free of added glues or other chemicals. Should be better for IAQ. A solid wood joist may or may not last longer than the 3/8" wide OSB web of an I-joist. It would certainly last longer in a fire or if it got wet. Does this add up to a more environmentally responsible choice, or does the I-joist win with the smaller trees argument?
This question is primarily about floor joists. Please share your thoughts.
