Replacing glass in older skylights is a unique challenge. We recently changed out broken laminated glass in a steel skylight. We typically do not see skylight designed this way due to changes in energy codes but sometimes just a pane or two in an old skylight is broken and requires glass replacement. In order to replace skylight glass and meet current codes we use tempered laminated glass products. The photos of the Old Town Glass crew below show installation of tempered laminated glass with a white interlayer (obscure) into a steel skylight frame on a flat roof.
