00:00To understand how CLT is made, I traveled a few hours south of Portland to D.R. Johnson Lumber,
00:11a family business run by Valerie Johnson. CLT has been used in Japan and Europe for more than a
00:19decade, but in the United States, D.R. Johnson is the first mill to make architectural grade CLT
00:26panels. By the way, I want to thank you for this very cool outfit here. You know, I'm thinking,
00:32what do you think? Maybe I could wear this on stage with the stones? Or maybe I should just
00:37join the village people? No, you're talking. That'd be the perfect place for it. You look like a
00:42national. Y-M-C-A. We maybe should adapt a song to that for CLTs. What do you think? We could work
00:50CLT. This is our CLT plant. It's where the new magic happens.
00:58I'm going to get up in the morning and I ain't going to say a word. I'm going to get up in the morning and I ain't going to say a word.
01:09The layup section is here to our right. They lay a layer longitudinally down and then they run the glue extruder over it. Then the short pieces come down. They run the glue extruder over that again and we put another layer of long pieces on top of it. We can go three limbs deep, five limbs deep and seven limbs.
01:31All the way up to seven. We can. And this is the machine, right? This is the press. Once the glue's laid up, it rolls into the press. The press compresses it to get all of the space out of it. We get both sides, ends, and down. Once you compress all that wood together with the glue, it's as strong as anything you can imagine. Well, it is. You've got all the strength of the wood fiber running both directions.
02:01We'll see you in the next video.
