On windows, doors, and siding
There is only one reliable way to compare windows and that is by asking for the NFRC* rating for each window that you are considering. NFRC labels are independently certified and rate the whole window performance by U-Factor and Solar Heat Gain Coefficient (SHGC). The lower these ratings are the better the window will perform. The priority of U-Factor versus SHGC depends on your climate. You should ignore all the sales hype and choose the best NFRC ratings for your climate at the best cost.
Energy Star is a window certification program administered by the Federal Government to help you select energy efficient windows optimized for your climate. A window must meet minimum performance criteria to qualify. These criteria are based on NFRC whole window performance ratings and are different for each of four climate zones as follows:
Northern Zone (blue): U-Factor of .30 or less, SHGC any
North Central Zone (yellow): U-Factor of .32 or less, SHGC of .40 or less
South Central Zone (orange): U-Factor of .35 or less, SHGC of .30 or less
Southern Zone (red): U-Factor of .60 or less, SHGC of .27 or less
Yes, any window or patio door ordered with a LowE glass upgrade will qualify for the Energy Star guidelines for the climate zone where purchased. This guarantee always comes in writing on your contract specifications so you will be assured of ordering and receiving the best LowE glass that is optimized for your particular climate zone.
Yes, you may be eligible to receive a 10% federal tax credit up to $200 for windows and $500 for doors that meet Energy Star guidelines. These credits had expired in 2011 but the new law, “The American Taxpayer Relief Act of 2012” has extended these tax credits to the end of 2013 and retroactively for 2012.

I have to start out by saying I went on the search for new windows I had several estimates done and I have to say that when the best window company came in to give me an estimate they were very open and very honest with their products with their pricing nothing is hidden that was the number one plus for me the second was the people that installed! Adam and his crew was absolutely incredible amazing above and beyond I can't think best window company enough for the work that they've done the cleanup afterwards the kindness while they were here and just very professional in all directions. I also need to bring up Keith and Nikki they are the ones that got us started Keith came out to give the estimate Nikki's the one who answered the phone and set up the appointment and I can't say enough about these two people either I've never been treated with such kindness and respect from a company that I've ever dealt with so I want to say Kudos I applaud you all and thank you for the amazing Windows the job and everything that you all have done for us I would highly and I say this again I would highly highly recommend this company and if I ever need anything in the future this is who I will be giving my business to.

We really appreciate Best Window Co for providing us with the lowest pressure, easiest estimate process. They were able to deliver the windows ahead of their original schedule date and their installer, Hector was a true professional and answered all of my questions during the install and sought my feedback several times to ensure he was doing what we wanted. Very pleased with everything so far.
