Marvin Essentials, then Kolbe Forgent then at very bottom of the list (any list not just this list) anything Pella or Sierra Pacific.......

Millworkman is correct, as usual. Rarely is the least expensive window the best option. Marvin's Elevate series is better, if you want to spend more money for a window that has a wood interior.

Thank You millwork and Ultra The Marvin Essential was the lowest quote. All quotes were U= .26 - .29, double low E and argon. i was surprised the Pella are 40% more than Marvin

I would suspect the pella’s to be higher if sold through a a Pella franchise.

I just had Kolbe Forgent impact casements installed last week. We ordered black exteriors with white wood interiors (except that garage has white Glastra, not wood). They are beautiful.

The insides are only primed at this stage and the plastic is still on, but happy to post photos. The crank mechanism is very smooth.

Hey There: We sold German made windows and doors for many years in the USA before we concentrated on window fashion only. I am very surprised about the numbers/quotes you share. Marvin and Kolbe should be the most expensive but are also the best option. Pella and Sierra Pacific are entry windows and often used by contractors. Please make sure you read the quotes correctly and compare them correctly as well. Still, very surprised about these numbers...

Marvin Essentials U 0.26 SHGC 0.34 VT 0.58

Kolbe Forgent U 0.26 SHGC 0.29 VT 0.55

pricing includes all casement windows and 2 sliders other two entry doors are seperate quote

I was blown away. nobonobody can explain it

So I went with Kolbe

Best window = Lowest Price

I don't understand what this means "Best window = Lowest Price".

In your pricing examples, Kolbe was $3K more than Marvin but you chose Kolbe. Also, blown away by. . .?
