Alpen vs Inline
I am comparing Alpen and Inline products. I have recieved quotations from both companies and I would like to pose a few questions to those that have a little more experience in this relam.
Both companies use fiberglass frames and Cardinal Low E Glass. Inline makes their frame and Alpen purchases the frame material through Inline.
Alpen makes a double pane window, their 525-s Series, that have a whole window U-factor of .19 for casements and .15 for pictures. Inline offers a triple pane window with a whole window u-factor of .17 for a casement and .14 for a picture.
My questions are as follows:
Will I notice a difference in performace based on the U-factor numbers here?
Will the triple glazed soft coat windows provide any other benifits beside a slight performance advantage? Such as noise reduction, strength, etc.
I am debating a nailing flange or strap anchors, but am drawn to strap anchors do to the price. Will a nailing flange offer any benifits over the strap anchors besides ease of instalation.
Thank you for any input. I have simplifed the variable with my windows in this post., however, I would like to point out that my sothern exposer windows will be taking advantage of a passiver solar design.
