I ran into this past summer. We ( me and 3 friends from college ) had purchased some pieces of engineered lumber for use in a detached workshop. I had cruised some shelves at the spot and was asking about using some engineered lumber elsewhere - namely for a commercial building ( A paint shop for boaters - you know, where you want your boat painted? ).
The owners told me that I could not use engineered lumber in a commercial building as it does not meet the fire code. When I asked why I could use it in a house ( they use it like water up here ) they said they had no idea.
Anyone have an idea what they mean?
I am curious as I am in the steps of planning for some home modifications and they all depend quite heavily on engineered lumber. Hate to find out I made a fire trap.
Thanks to all for your help.
