Pittsburgh Corning offers the LightWise line of pre-assembled vinyl frame glass block windows that come in 78 sizes and install like standard windows. The company's new 2-inch-thick glass block is lighter than the standard 3-inch glass block. The windows are shipped ready to install.

Designers order the windows through a window distributor or lumberyard. The white vinyl windows take two weeks to ship, and the tan frames take three weeks.
