5.2 REPAIR AND REPLACEMENT PROCEDURES
5.2.1 Solar Collectors.
Glazings
Most collector glazings are textured, tempered, low iron glass. Whenever possible,
replace broken lites with the same type and brand. (A lite is one sheet of glass.)
WARNING!
Always use tempered glass! Standard glass will fail rapidly, and
may cause personal injury or death if large pieces fall off the roof.
