Glass block windows have the unique ability to provide both natural light and insulation to a living space. They're often used for basement windows, but they can make any living space more beautiful. Glass block windows are practical alternative to standard windows, and they're often used in place of solid walls; they're even used for ceilings and floors.

Single glass blocks were first used to provide light in cellars and to the bowels of ships. These first glass blocks were square sections of conventional glass. Around 1880, glass blocks were constructed in the shape of bottles. They were mouth blown and had a slight opening. Even though these blocks were set in mortar, condensation always worked its way in. Machine-made glass blocks were the next stage of development, which were an improvement in size consistency. In the 1930s, improved machines created even better products. The Corning-Steuben and Owens-Illinois blocks were among them. These blocks were constructed by two halves of glass block pressed together at high temperatures, leaving a hollow centre and complete seal. The same basic principle of construction is used in making glass blocks today.
Glass or Acrylic
Some of the best features of glass block windows are their thermal insulation, security (over standard windows), excellent light allowance, and decorative beauty.
Acrylic block has been introduced as a less expensive alternative to glass block. When making your choice, consider that glass block is much harder than acrylic block, and cleaning will leave no scratches on glass. Routine cleaning of acrylic will leave scratches over time. Acrylic block also is easily scratched by workers during installation. Acrylic block windows eventually acquire a faded and cloudy appearance.
