Storefront transparency is a term used to describe the use of plate glass in storefronts. Plate glass is a type of glass that is made from a single sheet of glass, which is usually thicker than regular window glass. It is often used in storefronts to provide a clear view of the interior of the store and to allow natural light to enter. Plate glass is also used for safety reasons, as it is more resistant to breakage than regular window glass. Storefront transparency is an important part of modern retail design, as it allows customers to easily see what is inside the store and helps to create a welcoming atmosphere.
