   Hi Hunter,

   For budget tri-pane windows, we’ve used Alpen and a “local to our market” manufacturer called Thermo-Tech. I don’t have longevity data on either, but the products we’ve received from both manufacturers have been good. An architect I work with prefers fiberglass over vinyl, Silex (out of Canada) is her preferred manufacturer.

   I have Alpen and would hardly call them “budget”. I love the windows, but they were 23% more expensive than Marvin Elite double glazed.
