Crystal Series Textured Glass. Originally designed for Four Seasons Hotels, Crystal Series ingeniously diffuses light sources. Crystal Series is ideally backlit (natural or artificial), which causes bright illumination of each bead and creates a definitively posh ambiance. Crystal Series is often kiln-formed in 3/8” thick tempered glass. Crystal beads are then fused to the back of the panels and finished with an optional Lucent color. With over 150+ unique and exclusive glass textures and designs, Nathan Allan offers the largest assembly of hand crafted Architectural Glass products. Created for the A&D community, our Architectural Glass is used in wall partitions, balustrades, doors, dividers, storefront and facades. Nathan Allan has also designed 2 exclusive products for Glass Flooring and Glass Stair Tread applications. Each of these products is designed with our Glass Sandpaper safety finish, an incredibly durable and effective safety finish. Please contact us today in order to learn more about our glass products.
