Glass Block, various thicknesses (80mm, 100mm)
Hollow or solid glass masonry units providing light transmission, thermal insulation, and privacy. Available in 80mm and 100mm thicknesses with various patterns and finishes for architectural applications.
Hollow or solid glass masonry units providing light transmission, thermal insulation, and privacy. Available in 80mm and 100mm thicknesses with various patterns and finishes for architectural applications.
Glass blocks are architectural masonry units manufactured from pressed soda-lime glass, featuring hollow or solid construction. Standard dimensions are 190mm x 190mm with thicknesses of 80mm or 100mm. These units provide natural light diffusion whilst maintaining privacy, offering excellent fire resistance, acoustic insulation, and security. Commonly used in commercial, residential, and industrial applications throughout Australia.
