Glass Inserts are a great way to add style to a project. Durable, tempered glass inserts can be used in any of the glass or french lite doors we offer. Our top-of-the-line specialty glass provides a gorgeous look while providing the safety and durability of tempered glass, which in the event it is broken will crumble into small fragments instead of large hazardous pieces. Tempered glass is normal glass that has been through a process of extreme heat and rapid cooling which makes it stronger than normal glass. Through this process the break pattern of the glass changes from large sharp pieces to finger sized pieces. This property is often why tempered glass is called safety glass. Glass Inserts are 100% recyclable.
