There is a long thread on this topic. See below.

Mostly negative responses about the product, price and sales tactics.

Sounds like you have time to cancel the contract. I would advise you do so immediately.

Here is a link that might be useful: Any comments on Owens Corning Basement Systems?

I was a subcontractor for Basement Experts / Owens Corning for years. Worked my but off for them.
Just a warning for those subs out there considering working for them, in the beginning they pull money from your checks as an insurance policy to make sure you guarantee your work for a year. I can understand that. But once the year passes with no call backs they are to return the money.
Its been 2 years and I still haven't seen my $700.00. Beware subs, they'll screw you the same way they do everyone else.
