I use to have Milgard vinyls for a while and after a few years, I felt drafts and my house was getting colder and colder every month with my furnace on max! it turns out that window expansion and contraction broke the seals around the edges. Anyways...
I had a Penguin appointment last night. They did not come off like rude salesmen at all, more like a window consultant. Everything he said did point towards penguin, but he had evidence from cross sections of other windows, glass differences, etc. bottom line, it has an insulating factor of 10, my drywall is 12 so this is pretty good. Any other window on the market is r-4.2, and I've done my research! The PVC is the same vinyl as any other windows except that they extracted the petroleum and mixed acryllics and hardeners into it. The same material they use in the windows is boeing 747 fuselages, thats nothing to laugh about. The insulation in their frames is the same in your refrigerator. This window is no joke. They guaranteed me 40% minimum energy savings or pay the difference, and in the course of 10 years i'm set to save over 20k. I called my real estate agent today, he checked with his office and did comfirm that with any new gas filled window the price of the home will increase 118% on average, depending on the consumer reports expected lifespan on the window. So for a Milgard builder's grade window 8-10 year shelf life, 110% will remain until that shelf life expires. The penguin window will retain the 118% for 50+ years. With all the evidence I've gathered and reserach I've done, I am completely convinced I have just purchased the best product on the market today. I also know why Penguin gets alot of flak.
Penguin, has a product that costs about 5-6 times more to make. The only way people will buy is if there are sales people doing door to door appointments. This makes lots of sense. Would the majority of people going to Lowe's pick up a 2,000 window, or would you go with the 150 window? At a hardware store, no financing and no custom sizes.
