100% of ALL Four Seasons Products Use Tempered Safety Glass!

Our glass is four to six times stronger than ordinary window glass and much safer too. In fact, our tempered safety glass has smooth rounded edges and meets ANSI 297.1-1984 codes for safety. If broken it would shatter into harmless rounded pellets.
