Good window vendors

BILL WICHERS | Posted in Green Products and Materials on

I’ve been researching windows for an upcoming project (big reside where the windows will all be replaced) and I’m looking for ideas as to vendors. I’m aware Intus has basically left the market. I have a bunch of reasonable size awning windows that are below good size picture windows, and several good size casements. Two double hungs will be replaced with casements for better sealing. 

I’m primarily looking at fiberglass windows but would consider good PVC windows. Some windows need laminated glass (for sound, not impact rated), and maybe a few triple panes. 

Most of the info out there is many years old. The usual Canadian manufacturers have lousy websites so there isn’t an easy way to get quick info from many of them. I’m interested in expieriences and recommendations from people who’ve tried any of the options out there. I’d been looking at Marvin integrity, but I’m thinking it might be possible to get a better product for less money from one of the lesser known companies. 

Any info is appreciated.

    I suggest you read this article: "What Windows Should I Buy?"

    HI Bill -

    I am just finishing an article for BuildingGreen on thin-glass triples (see this LBNL resource
    : I spent quite a bit of time on the phone and email with Brad Begin of Alpen Windows. Passionate for window performance and very sharp. Give them a look.

    I am very happy with my dealings with Enerlux windows

    I'll vote with Peter Yost and also suggest you give Alpen a close look. Happily enjoying a house full of their windows at relatively high altitude, days near or below zero this winter. Third year of enjoying sitting in the breakfast nook not freezing, like I did in our midwest double pane home.

    Fiberframe Comfortline is a fiberglass window that looks like a good alternative to Canadian fiberglass, located in the US (Ohio). I got some quotes on them once and they they offered good prices and samples looked like good quality, but we went in a different direction on that project.
