Go to my backyard and get a huge piece of foam.
I have left over pieces of SIP panels in my back yard.
In fact last weekend I just cut up a huge one because I was sick of moving such a huge chunk.
keep in mind these pieces have OSB on one side of them.
If you fastened a couple together you could easily float a car.:biglaugh:
Since we are on the subject does anyone know where to get rid of huge pieces of foam?:biglaugh:
