Glass Installation
Bob and Ryley install sloped glazing on a solar greenhouse with the help of Mark Santos. They use a commercially available mounting system to attach the glazing, which consists of an extruded aluminum railing with a neoprene gasket. The gasket forms a weathertight seal. The railing also has a small trough to catch condensation. The glazing itself is a 1-inch sealed glazing unit. The outer sheet is tempered glass, but the inner sheet is laminated glass, similar to at the corner with another sheet of glass. This is called "butt glazing" because there is no additional support. automobile windshields, which improves safety.
