Tempered glass is a critical component of frameless glass pool fencing, offering strength, safety, and durability while maintaining an elegant, almost invisible appearance. At US Glass Fence, we use 1/2″ thick clear tempered glass, which is eight times stronger than standard glass. But what makes tempered glass so tough?
Let’s take a closer look at how it’s made and why it’s the ideal choice for modern glass fencing solutions.
The Tempering Process: How It’s Made
Tempered glass undergoes a specialized heat treatment process that enhances its strength and safety. Here’s how it’s made:
Cutting and Shaping – The glass is cut to the desired size and shape before the tempering process begins. Since tempered glass cannot be altered after treatment, all holes, edges, and fabrications must be completed beforehand.
Heating – The glass is heated in a furnace to temperatures exceeding 1,100°F (593°C). This high heat softens the glass, preparing it for rapid cooling.
Rapid Cooling (Quenching) – The glass is then subjected to a high-pressure blast of cool air, known as quenching. This rapid cooling creates compression on the outer surfaces while leaving the core of the glass in tension. This internal stress distribution makes tempered glass significantly stronger than regular glass.
Why Tempered Glass Is So Strong
1. Superior Strength
Tempered glass is up to eight times stronger than annealed (regular) glass, making it resistant to impact, wind loads, and environmental stress. This strength is important for frameless glass fences, where durability and safety are top priorities.
2. Increased Safety
Unlike regular glass, which can break into dangerous shards, tempered glass shatters into small, pebble-like pieces when broken. This significantly reduces the risk of serious injury, making it an ideal choice for pool fences, balconies, and railings.
3. Heat and Weather Resistance
Tempered glass can withstand extreme temperatures and sudden temperature changes without cracking. This makes it perfect for outdoor installations where weather fluctuations can be a concern.
4. Customizable and Versatile
At US Glass Fence, we use high-quality fabricators to ensure that our tempered glass panels are free of imperfections and have polished edges. Our glass can be custom-cut to accommodate grade changes, steps, and slopes, making it a versatile option for any property.
The Perfect Combination: Tempered Glass and Mergelock Posts
While tempered glass provides strength and elegance, our Mergelock stainless steel posts ensure stability and seamless installation. These posts are manufactured using the Lost Wax casting method, making them smaller, stronger, and more attractive than conventional alternatives. Their enclosed clamping mechanism eliminates visible screws or fasteners, maintaining the minimalist aesthetic of frameless glass fencing.
Enhancing Performance with Nano-Coatings
To further enhance durability and reduce maintenance, we recommend applying a nano-coating to the glass. This proprietary coating creates an ultra-smooth surface that repels water and prevents dirt and debris from sticking, keeping your glass fence cleaner for longer.
Tempered glass is essential for frameless glass fencing, offering unmatched strength, safety, and aesthetic appeal. Its specialized manufacturing process ensures durability, while our high-quality glass panels and Mergelock stainless steel posts provide a seamless, modern fencing solution.
