There are 3 primary styles of glass block you can select from Masonry & Glass Systems for your basement windows. All of the patterns have a distinct look and offer various degrees of privacy.

Wave Pattern is our most popular style and continues to be selected by the majority of customers. It distorts images and so offers good privacy with plenty of light and seems to blend with almost any architectural design.

Iceberg Pattern is very popular with customers that want a higher degree of privacy than Wave pattern. The Iceberg style makes a window totally obscure and so is ideal for bathroom windows as well as basement windows where privacy is a top goal. Iceberg also allows plenty of light to enter a room.

Pristal Pattern is our most private block. Its diamond pattern can turn prismatic in the right light conditions. It is smooth on the outside faces of the glass and so is easy to keep clean. It also allows plenty of light to enter a room.
