Thanks CWirick - we're deciding between these as well. At the 11th hour i am also getting Kolbe and Jeld-wen priced out and am finding that these aluminum clad products are actually relatively close in price (and in some cases cheaper) than going all fiberglass. The warranty is nowhere as good on these as what Milgard gives on their products though and not sure if ultimately anyone notices the difference between a fiberglass and a aluminum clad/wood interior product after taking into account the wood framing around the windows. Also looked at the Milgard Essence product this weekend and it looks really nice but is pricier than both the Marvin Ultrex/Wood and Marvin All-Ultrex products as well as the quotes i'm getting on Kolbe and Jeld-wen but the nice thing with Milgard is all the options you get on sizing...and the warranty is great. decisions decisions. thank you all for your perspectives and advice...feel free to add more as i'm obviously still undecided. This is the one area where i'm somehow less price conscious than my wife...who thinks fiberglass is fine and gives her more dollars to spend on fixtures/granite/shutters/etc...

just had one elevation of home installed with marvin infnity fiberglass inserts.Purchased the argon 272 as opposed to the 366 glazing.Clincher was the product with installation and service are provided by same vendor.did not want to break up purchase at one source, installed by another source, etc. I am told these are good windows, have yet to stain and topcoat and finish trimming and caulking,on the interior. Rear of home gets more weather fluctuations..so, researching a clad product or seeking info as year 2013 will bring higher standards for energy star rating including triple glazing.Windows are complex.Will say these sliders are easy to operate and look good. Also got some casements;not sure they are better than other brands.Exterior looks far better than other"replacement windows" that you see thrown up all over the place from TV vendors [many of those are vinyl, I realize.]

Our house was built in 2001. We have a double front door and garage entry door, both fiberglass by Thermatru. The front door with full lite glass has had serious warping. The top and bottom both twist in. This is in a covered area facing East. The garage entry is fine, but the seal went out in the 1/2 glass. I sent claim to thermatru direct. Via email I was able to get replacement. But not what I wanted. They were willing to send me one new door slab and 3 new pieces of glass since our style was discontinued. That would have been a nightmare trying to get the new one to match both inside and outside with paint and stain. We compromised with 2 new front slabs and 1 new glass. They sent it immediately. We are just getting around to replacing with spring weather. I’m exasperated and haven’t even started. Seeing what they sent, it is going to be a huge hassle to change out the glass AND strip and repaint the surrounds, etc that didn’t get replaced. Now looking at steel doors from Menards, Mastercraft. I see the good and bad reviews, but honestly I’d be happy if that lasted 2/3 the time these did as these fiberglass doors are crap. I want durable fade free doors. I did buy a Home Depot door for garage to house, with glass, not fire rated, my concern in that. Our installer said it was the easiest door he’s ever put in and to this day it opens and closes perfectly. On at least its 5th year. Didn’t spend more than $500 for it.

We got an oak louver door through a local lumberyard/hardware store in '04. The door was from Rogue Valley--www.roguevalleydoor.com (style/model # 733). Their doors weren't cheap in '04, but they were the only ones we found who made a full louver door without a center stile, and would make it in oak. We had it stained to match our front door (and all the veneered oak interior doors that we installed). It's the nicest looking interior door in the house!
