I am enjoying my new Lifetime Windows. Besides looking wonderful, my electric and heating bills are at least $100 less every month. I had my windows installed over a three year period and noticed my electric bills going down and down. For the hot Arizona summers that is saying something. Thank you to all the very professional employees at your company.
