Each door comes tempered in a 3/8" or 1/2" thickness on premium quality regular clear glass. Edges are fine polished or can be made to your specification. The panels are tempered in an SGCC certified facility, ensuring safety. We also offer the option of upgrading to an EnduroShield coating, which keeps the glass looking clean, cuts cleaning time by being water and oil repellant, and is insured through a 10 year warranty.
