windows and doors for workshop – GreenBuildingAdvisor

I’m having the usual grief in finding windows and doors, the biggest being finding a place that will even give a quote. I don’t understand why they even have an rfq form if they just ignore them. The only one I’ve managed to get a quote for is North Star, and the specs are underwhelming. U-values of 0.27 for dual and 0.24 for triple glazed, and I was told that’s centre of glass, not whole assembly.

Two questions. 

1. Given that this is a garage/workshop, should I even bother with higher performance windows? I have only 5 (60×36) windows and two doors in an 1800 sqft building, but I do plan to fully condition it and perhaps one day it will be converted to an ADU. Part of me wants to just order cheap windows and doors now, and maybe upgrade them a few years down the road. 

2. Any recommendations for windows and doors either near London, Ontario, or maybe a place further away that’s easy to deal with (ordering and delivering)?
