I looked at their site and id say they are not only cheap but cheap as
in construction. They dont make windows, or rate r or u values, or say
they warranty glass. Argon low E ? who knows. Franlky you dont know
what you are buying, Id say you can do better . If you want cheap OK
thats what you are paying. Do you want top insulating in the industry
look at HURD. You realy get what you pay for.
