When selecting glass for outdoor furniture tables, safety should be your primary concern. The straightforward answer is no - you should not use regular annealed glass for outdoor furniture applications. Tempered glass is not just recommended; it's often required by building codes and safety standards for outdoor tables.
Tempered glass, also known as safety glass, undergoes a special heat treatment process that makes it approximately four times stronger than regular glass. When broken, tempered glass crumbles into small, granular pieces rather than sharp, dangerous shards. This characteristic significantly reduces the risk of serious injury, which is particularly important in outdoor environments where temperature changes, weather conditions, and accidental impacts are common concerns.
Regular glass poses multiple risks when used outdoors. Temperature fluctuations can cause it to expand and contract, leading to spontaneous breakage. When regular glass breaks, it creates sharp, jagged edges that can cause severe cuts. Furthermore, regular glass cannot withstand the same weight loads or impact forces that tempered glass can handle effortlessly.
For optimal safety and durability, choose tempered glass that's at least 1/2 inch thick for larger tables. Ensure proper installation with adequate support and consider textured or frosted finishes to reduce slipperiness and hide minor scratches. While tempered glass may cost slightly more initially, its safety benefits and longevity make it a worthwhile investment for any outdoor living space.
