Professor Kennedy teaches on the importance of ventilation.

In the Replay today, Ron questions Kevin about the appeal of ProVia®

products including windows, doors, and siding, among his customers. Three

factors stand out: the ProVia warranty, appearance, and durability. Our

Horror Story today deals with the replacement of a window that failed to

meet HOA standards. As you can imagine, this caused much needless

aggravation. The subject of our Feature today is ventilation and Professor Kennedy schools us on the importance of it.
