Confusion reigns supreme!

I also like using the soundboard and second the above post about painting. That will help seal it nicely as well as provide a base for landscaping.

I've been using the sound board, ceiling tile type stuff, for several years now on the halloween layout that I have been doing in the garage. It has lasted for quite some time even though it seems to get new holes cut most every year to accomodate a new building/accessory power cord. I prime it when it is new, tinted in an earth tone, and it is in turn screwed down on the 1/2" plywood deck  with 1" drywall screws. For these temporary layouts I use "O" and 027 track which is secured to the sound board with 3/4 or 7/8 #4 screws. Just don't go deep enuff to contact the plywood, if you do you will reduce the effectiveness of the insulating material.

IMHO the sound board holds screws better than homasote.

Please bear with me.  This is sort of a follow-up to my previous post regarding Homasote in Florida. If I elect to go with one of the alternatives to Homasote such as extruded foam Insulation, sound stop, hushboard etc., do I screw the tubular track into these products as I do with the Homasote or is there another means of which I should be aware?    Also, will the alternative products hold the tubular track as well as the Homasote?  As always, many thanks.
