| Be sure to compare snow load. I personally like the 8' spacing with the heavy trusses that are notched into the center of each laminated column. When I had my shop built last fall the national builder whose name begins with M that uses 7.5' spacing was going to use trusses with a 16 pound snow load which is minimum code for my area. A local builder was going to use trusses on 4 ft centers with 30 pound snow loads. For not much more money I had him upgrade to 40 pound load trusses. | |
