Glass block windows are one of the architectural features often used in homes and businesses, designed to fit within a masonry wall. They are made up of 8 x 8 inch blocks that can be used on the exterior and interior of a building, often use as a natural light source when no ventilation is needed. The function of having a glass block window is to provide privacy and light source. It also creates a feeling of openness in a space that a regular window doesn't provide. Glass block windows come in 8 x 8 inch units so that they can be laid on a regular concrete block. Unlike sheet glass, glass blocks are hollow and heavy. Recently, glass block windows can now be made using acrylic glass so that they are more lightweight and affordable on your pocket. A regular glass block has to be laid individually like bricks in order to make the design of a window. Acrylic glass block is now available as a pre-assembled unit in a window form so it doesnít require any masonry skills to combine the glass windows to the concrete blocks. The benefits of having a glass block window installed are the sense of privacy while natural light is still permitted to enter the room. Glass block windows are thicker and durable than the regular glass. They are also resistant to any breakage and vandalism, making it a best choice for any unsupervised area. It is also a great alternative to ceramic block applications for they are non-porous and easy to clean. They are also energy efficient for they keep your home more comfortable because of its size and construction.
