Protee sub floor

[Crusty]

Has anyone tried using coolroom sandwich panel as a sub floor? (Foam sandwiched between two thin sheets of aluminum)
My floor has to be portable as the space doubles as garage, I've just purchased some 1/2" ply sheet approx 4x8' to build my floor, by the time I built it up and cover it, it's gonna weigh a ton. At least I will get to golf and workout at the same time... :unsure:

Great info. I'm waiting for the delivery of my Protee system now, and I'd like to get started on the sub floor. It's a garage build, and I was planning on 2x4s (on the flat - 1.5" high) with 5/8" T&G OSB on top, and then padded putting turf atop that. I think that brings the height/depth to just about 2 5/8"

My first question...does this provide enough depth for the Protee floor hitting sensor? I'd prefer not having to stand the 2x4s on edge, if possible. From the pictures above, it looks like the panel housing the main sensor is actually 2x4's on the flat also.

Second question...should I support the Protee hitting sensor with anything or does it lay flat on the floor? I see some with foam added underneath the sensor, but I think that's to adjust the height rather than providing some base for the sensor. It should fit firmly within the framed base.

I appreciate the help and suggestions.

The ProTee sensor is 2 3/4 inches thick, but not sure if that includes the the thickness of the turf top or not.

The dimensions are given here:

Safest bet might be to wait until you get the unit.

I supported my sensor on a piece of plywood but partly because I had to make up for the proper height. A piece of dense carpet underlay between the sensor and the concrete might give you some peace of mind. Plus, you may have to adjust the height of the sensor depending on the thickness of the covering you put on the subfloor.

Are you getting the putting sensor as well? If so, you'll have to make some allowance for the cable and connector which connects to the main sensor.

If you are planning on 16 inch centers the 5/8 OSB is fine but if going with 24 inch centers I'd consider 3/4 inch.

The lumberyard (anybody use that word anymore?) should have 2x3s which would only be about 2 1/2 inches on edge.

Another approach is to use shims or spacers to make up the proper height for the subfloor. Your garage floor may be sloped, so you might end up having to do this if you want a level subfloor - and you probably should go for a level surface.

On my outdoor hitting mat, the frame ended up very heavy, so I attached 2 small handles to one side and fixed castor wheels to the other. The slightest tilt allows it to me mobile and I can wheel it to the storage area. You could also extend your top over the castors and add a rubber strip so you can prop it against a wall without fear of it sliding down on the wheels

Thanks for the replies! Yes, I also ordered the putting sensor and I understand it isn't as deep as the hitting sensor. I will likely wait until it all arrives just to make sure. Since the floor does slope I will be leveling it as well, and this would give lots of space underneath. It does seem best not to become impatient at this stage. :-) Thanks!

I like the wheels idea, although in my case the platform will be about 10 x 10. I may add hinges to one side of the platform so I can fold it back when not in use. The way this is being built, it will encroach on the second garage bay that will occasionally have a vehicle in it.
