I have read some of the other threads about building a module and have a few questions.

People have mentioned using the foam insulation for the top of their module with a couple of stringers to support the foam. Am I understanding this right?

How do you mount track on the foam insulation?

Also, is there any reason why I can't just use "L" brackets to connect the sides of the frame to make the 2' x 4' box?

Help and suggestions are greatly appreciated.

Thanks,
Jon
