Thanks,
that's what I thought you did. My brothers friend up here is an insulation installer, he has his own company, so I called him tonight. He said he doesn't use the 703 much but ,thinks he pays $10 for a 2x4 sheet of 2". For my reflections I was going to use a 2" and a 1" with the backing on it to give me 3" and that would leave a 1" air space in the back. Also the viynle ( I can't spell that word ) to help hole in the fibres.
