Decidedly smallish this year. Large companies like APOC that usually have multiple booths was noticeably downsized. Bigger yet companies like Henry Company had no booth at all.
If this tradeshow is any indication, SPF foam has slowed as there were far fewer foam-related booths than years past. I saw only 1 trailer-mounted foam rig and it was a used unit with rust on the trailer. The big exhibitors this year seemed to be metal and solar.
