I wish to protect the floating laminate flooring of the room I am building a home gym in. Therefore, I will lay down plywood sheeting to spread the load and prevent scratching.
I am having trouble deciding on the configuration. I would like to optimize for these factors: maximize load distribution, minimize thickness, minimize cost, minimize movement, and minimize effort - in that order.
I think I should have at least 15mm of thickness - however I'm having difficulty with quantifying that. The thickness should not exceed 25mm (as I won't have enough clearance from the ceiling).
I thought of having one of the following two configurations:
- Red is the squat rack
- 2x 12mm sheets at the bottom, vertically aligned
- 2x 9mm sheets at the top, horizontal aligned (so nothing to get push apart when squatting etc)
- Blue circles: holes drilled through both layers of board. Will put threaded inserts in the holes so I can screw the layers together and dismantle easily if I need to.
- 2x 18mm sheets, horizontally aligned
- Blue: some kind of fastening.
Which of these do you think is better?
Can either be improved? (e.g. can I use 9mm for both layers on the complex option?)
What would be the best fastening solution for the second option?
Is there a better way?
N.B. Plywood in my area is mainly sold in 9mm, 12mm, 18mm and 25mm thicknesses. I will be using structural plywood.
