Glass Block or Insulated Replacement Window
December 19, 2013 7:44 PM Subscribe
So I have been working on my house and making it energy efficient. It is now time to replace the basement windows in my split level. One double wide window needs to be replaced with one that opens to meet code, but the other three single wide windows do not. Would I be better installing glass blocks in those three, not vented, or installing either a picture, slider, or another type of insulated vinyl replacement window? If I should do a replacement window, which type should I use?

The window openings are in the foundation. The bottom and sides abut cement block with the top of the opening being painted, pressure treated wood. I am looking to get the best seal and insulation value for everything. Energy efficiency trumps everything for me. I will be doing all of the work myself, but can get assistance as needed if a two person job would be significantly easier. I have very high carpentry skills so nothing really scares me. Rough openings for the three needing replacement are 35 inches wide by 22.5 inches high. I have enough space to install 4 inch deep glass blocks or any other type of window. Please let me know what you think, I have been thinking this over for more than a month and have gone crazy looking at numbers and options.
