When I started my screen wall I was concerned about warping that is typical of standard 2x4's. Most of the lumber you find at HD & Lowes leaves much to be desired. I didn't want to spend all that time desiging and building a screen and screen wall only to have fit issues as time went on.
After much research here on AVS, one of my local boys, BigMouthinDC
, turned me on to this product: Chilean Finger-Jointed Engineered Lumber
. Here's a link to his original post
with a picture of the product and here's a link to the manufacturer's pdf spec sheet
. This stuff is awesome and straight as an arrow. It's a little more expensive than standard lumber but not outrageous. I plan on using this material again as I tackle non home theater projects around the house.
Take a ride over to Home Depot and check out this material. It's usually found on the end cap of an isle near the molding. I think it's actually used as exterior house trim???
With all that said I've seen numerous local theaters using standard lumber without any issues. I guess if you go the standard 2x4 route just take your time finding kiln-dried straight lumber. Maybe try a local specialty lumber yard (if any still exist in your area).
