Laminated plyboard works awesome.. ive used it to build my whole room.screwed it to frame then used bathroon white waterproof caulking for corners and joins.i have magnetic latches that help keep the door shut and used 2-4 mmm soft rubber door draught seals.only thing wrong with my room i should have made it bigger lol..
you used this instead of durafoam?
for the door, door frame, I need a piece wood to mount drivers and controllers on, and a few other spots I could see using it instead of plywood but durafoam with the roofing style screw with the 1inch ring build it I see as the fastest way to get it up.
I can see/image it’s a lot quicker than a lot of other stuff and probably a good bit stronger than the insulation board.
i was going to buy 2 pieces of drywall and 1 of 1/8 plywood for roof and outer wall but I think the laminated stuff would work well for these 2 spots. Give more strength to ceiling and doorway + door
the magnets are a great idea
