    Tempered Glass Panel FAQs


    What is the difference between ceramic glass and tempered glass?

    Tempered glass is regular glass that is "cooked" and "cooled" very rapidly to lock the glass molecules in place. This tempering process gives the final product a couple of unique features. The strength of the glass from impacts and the temperate range is increased. The newly tempered glass is then able to withstand temperatures up to about 400 degrees. It is used in low-temperature fireplace doors - like bi-fold doors, for this reason. It is much cheaper to produce than Ceramic glass products that can withstand such high temperatures.

    Why is tempered glass called “safety glass?”

    Tempered glass should be used when standard glass could pose a potential danger. It is four to five times stronger than normal glass and does not shatter into large chunks when broken. Manufactured through a process of extreme heating (tempering) and rapid cooling, tempered glass is significantly harder than regular glass.

    The tempered glass is much harder to break when hit straight on. But if broken, this process causes it to shatter into small, oval-shaped pebbles. This eliminates the danger of sharp edges. This is why, along with its strength, this glass is often referred to as ‘safety glass.’ The tempering also raises the heat resistance up to about 400-500 degrees F. This is why this glass should be used in any situation where there is a danger of the glass breaking due to impact or extreme heat.

    Our custom safety glass options are available in many different sizes and thicknesses. If you need a specific size, contact us for a custom quote.

    Is this glass suitable as replacement glass for an oven door?

    Yes, tempered glass is a suitable choice for a replacement oven door. Due to its high heat resistance of up to 400-500 degrees F, tempered glass is able to withstand the high temperatures generated within your oven while still providing you with the same clarity and visibility as standard glass. 

    What can I use tempered glass cutting for?

    The thermal process that cures tempered glass also makes it heat resistant. Tempered glass is used to make the carafes in automatic coffee makers and the windows in ovens. Computer screens, skylights, door windows, tub enclosures, and shower doors are more examples of places you will find tempered glass. Building codes also require the windows of many public structures to be constructed from tempered glass.

    Do you do custom tempered glass?

    Yes, we do offer custom tempered glass options. We have a variety of sizes and thicknesses available to accommodate any project. We use only the highest quality glass for our tempered products. Our tempered glass is designed to be more durable and heat-resistant than standard glass, so it can handle higher temperatures without shattering or breaking.
