Point #1 – IG LoE II Argon Insulated Glass as a part of Marvin Windows installed in other parts of my home are unnoticeable, but may have a slightly grey layer (not blue or purple) on the inside of outside pane that screens solar heat during the summer. The Marvin Rep advises that their glass is manufactured by “Cardinal Glass”; and, is only available for replacements on other Marvin windows or doors manufactured replacements.

Point #2 – Other leaking insulated glass in windows & doors in my residence were Pozzi (now jeldwen), which have reach their normal life cycle; and, are in need of replacement(s). Several local contractors in Cincinnati purchase LoE insulated glass from either Pilkington Glass (soft &lighter) or Guardian Glass (hard&darker) Companys. Problem is that both of these products have a “blue or purple color cast” when sunlight hits the outside panes. This unacceptable color cast is not noticeble with Marvin Windows/Cardinal Glass product.

Point #3 – Since replacing all windows & doors in a kitchen room addtion with the Marvin/Cardinal Glass product is out of the question regarding costs, is the Cardinal Glass product in Point #1 available for purchase anywhere for replacements in my old Pozzi (Jeldwen) sashes? The only other option is Clear-Clear (non LoE) to match an adjacent Clear-Clear picture window (non LoE). This blue & purple cast is unacceptable. Any Ideas??
