If you're looking for a way to lay up glass block without mortar, WoodGlass may do the trick. The unique wall system uses a prefinished wood frame to enclose the manufacturer's line of metricsized glass block and can accommodate straight, angled, or curved wall designs. Installation requires no special tools because the glass blocks are held in place by precut vinyl strips, which friction fit into grooves in the frame, a feature that also makes it possible to disassemble the wall and relocate it. According to the manufacturer, WoodGlass is suitable for both interior and exterior applications, such as entry door sidelights, as long as there is limited exposure to moisture. Each frame is custommade of beech, but other species are available
