Glass Block Windows

If you have a basement or crawl space with windows - hoppers, if you will - consider switching them to glass block. Glass block offers the obvious - safety. You can go with clear, frosted or glass angled, depending on your privacy needs. However they also offer energy efficiency, with an R-value of 1.96 - almost twice the R-value of a 1/8" pane of glass.

Glass block windows can come pre-made or custom made. HZG recommends that if you have 2 windows in a space, make one of the glass block structures vented. In our basement, we have 4 (2 per side) and we vented the two that were across from each other.

The cost of installing GBW ranges from $125 - $200 for non-vented, $175 - $225 for vented.

Besides the advantages listed above, the maintenance is great - no more cleaning the panes - just squirt with a hose.
