Triple glazing worth it?
New double wall house, western Massachusetts – climate zone 5.
I am ordering Marvin Ultimate Clad windows; a combination of casement, double hung and sliders. The south side of the house are specified as double glazed and glass doors are not available triple glazed. This leaves 7 out of 23 openings double versus triple glazed.
Is it worth the extra $4,800 (12% of total window and exterior door costs) for triple glazed on the balance of windows?
