Anti-slip Walk On Surfaces

The top layer or walking surface of your skylights or glass flooring has two main criteria. Primarily, as a design feature, it should look great and be pleasing to its owner. It should be a reflection of the room it compliments. Secondly, it must meet the safety requirements of the local building codes. It must provide a safe walkable surface, being slip resistant as well as strong and durable. Here at Glass Flooring Systems we have established strategic alliances with many the best glass flooring suppliers in the world. This enables us to provide you with a variety of walkable glass options. ALL OF OUR GLASS MEETS the majority of building codes throughout the country, including loads and thermal requirements and missile impact ratings.
