Replacing 11 windows on 1967 home with original builder aluminum single pane in hot dry central CA. First two quotes from big box stores obviously, Lowes quoting the Reliabilt Cascade Series 9100 and HD the Simonton VantagePointe Clear Value ( 6500?) Still have to get local window installer quotes.

We aren't real picky about the look, sound dampening or even energy efficiency because we're assuming even the low-end newer stuff is miles better than what we have now. It's clearly not a high end home but if we sell the house we don't want them to look like junk either. We don't even open the windows, so we're putting our efforts into evaluating the slider door quality most.

Is there a major difference between these two Products? Not asking about installer differences like big box vs. local guy, etc. Lowes estimate offers only a 1 year labor warranty on their contract while HD is lifetime original owner, right?

The quotes were...Lowes=5000, HD =7200.
