Serious Windows Prices

Serious windows prices range from $450 to $2000 or more installed. The company was a Sunnyvale, California based manufacturer that made vinyl and high end fiberglass windows. The company experienced financial troubles during the 2009 - 2012 recession and was purchased (assets acquired) in September by Alpen High Performance Products out of Colorado. Prior to this, the company was Kensington windows, which went bankrupt somewhere around 2008 and was bought by Serious, which then rebranded the windows. In short, consumers should be wary of purchasing these products at this time due to the changes going on with the company. Read Serious window reviews.

Serious Quantum 2 (600 Series)

The Quantum 2 is the same window as the 600 Series and comes with a lifetime warranty. It has a heat mirror, which is basically a special film between the glass panes that offers energy efficiency comparable to a triple pane (but without the added weight of the third pane). It uses a pocket sill, which is not always well reviewed by contractors and installers. The window offers strong performance numbers, although the window tends to be very expensive.
