Hi, I am trying to decide on the better window. Please can someone help.
Install Okna 500 Insultec VS United series 8000. I was also told about the Okna 500 deluxe, from Okna. (hope they are the same.) The price for installation is only about $180 diff, with United costing more. I am confused about all. The warrenties for the Okna are lifetime and the United Limited. Please help me & educate me. Thank you all!
