Hi Peter,
PS foam is available at Home Depot and Lowes.
EPS foam is expanded with steam and is not the same as EXTRUDED PS foam.
Owens Corning eps foam is pink, Dow is blue. Don't buy the white as it is just styrofoam.
A 4 ft by 8 ft sheet of EPS foam 2 inches thick is about $25 bucks. This is what you need to use. Lowes handles both at about the same price per sheet. Take your finger and push it into both products. The EPS foam is much more rigid and will do a better job.
If you cut it on a table saw you need to do it outside. The dust will be drawn to everything and it will be impossible to vacuum it out of your shop. If you have a band saw it will be much safer than a table saw. You can also make a jig using a VERY sharp knife to cut it; watch your fingers. If you have a good table saw and a 60 tooth carbide blade you can do the job best. You will need a friend to pull the material through the saw as you push it. You also need to know the importance of keeping the material tight to the fence.
Polystyrene, extruded or steam expanded, will melt and bond to a table saw blade if the material isn't pushed through fast enough. The result of too slow a feed will result in a VERY fast kick back of the material. Don't be afraid of the saw; take control and you'll have no problems. On the other hand, use a knife and a good cutting fixture and you'll be fine.
You can buy an adhesive from FOMO products that is available in a 12 oz can with a straw tube to adhere it all together with. Unfortunately it's over $200 bucks a case. Use Elmer's glue instead. Latex paint will bond and give you the esthetic look you need.
I plan on doing just this in a few months to finish off my music room.
Peter, IMHO, your thread can contribute sonic improvements to "Gonners" that may not be matched by any other DIY project on a cost to benefit ratio I can think of.
I'll look forward to hearing how your project works out.
Ken
