Glass block, also known as glass brick, is an architectural element made from glass. Glass blocks provide visual obscuration while admitting light. The glass block was originally developed in the early 1900s to provide natural light in industrial factories.  The most common shape of glass block is square, the most common length, width and thickness of glass block are 190x190x80mm or 190x190x95mm.  The glass block with the length, width and thickness of 145x145x80mm or 145x145x95mm also sell well.  There are many decorative patterns such as cloud-shaped, parallel, slanted strip, lattice, bubble, raindrop, ice crystal, water shadow, mesh-shaped, popular pattern, gemstone grain, diamond grain, etc. and many colors such as pink, green, blue, grey, brown, gemstone blue, gemstone green, etc..

Product Feathers:  1) Environment Friendliness:  Belonging to sodalime silicate glass system, glass block, a transparent material, is made by melting silicate inorganic mineral substance materials such as quartz sand, soda ash (Na2CO3) and limestone at high temperature, being a veritable eco-friendly product.   2) Heat-shielding:  Due to the diffuse scattering of hollow glas block and internal negative pressure cavity, a room can get enough light rays and the interior temperature does not rise under strong solar radiation in summer.  In winter, the difference between indoor temperature and outdoor temerature can reach 40 degree C and the air humidity is not influenced because of low thermal coefficient and great loss of blocked heat in the negative pressure cavity.  If the glass block is applied to a building, the room gets cool in summer and is away from torridness, and warms the room, does not cause dryness and save energy in winter.   3) Sound Insulation:  Thanks to sealing negative gas in the hollow glas block, the block has high sound insulation property.  4) Light-transmitting and Non-perspective:  The light-transmission coefficient of white hollow glas block is 75%~85%, which is similar to that of the general double-layered hollow glas.  There are various decorative patterns on the surface of the glass block, so the block is non-perspective, indoor imperceptibility is realized, light rays are scattered around the room, discomfort caused by direct solar radiation is solved and the indoor luminous environment is improved.  5) Fireproof:  The fireproof level of hollow glass block is GB class A.  Accordingl to Japanese law, it is recognized that single-layer wall has the same performance as the second kind fire door and double-layer wall has one-hour fireproof performance.  6) High Compression Resistance and Shock Resistance:  The hollow glass block has high compression resistance and shock resistance, so that the dead weight of the hollow glass block can be ignored even in design and constgruction of very high glass block wall.  7) Atomization Resistance:  The hollow glass block has outstanding performance in resisting pulverization.  For example, the surface of the glass block does not atomize or form dew when the indoor temperature is 20 degree C, the humidity is 60% and the outdoor temperature is 2 degree C below zero, so that the erosion of atomized vapor to the frame is prevented.

Application Range:  The hollow glass block has noble, elegant and magnificent decorative effects.  It is widely in banks, offices, hospitals, schools, hotels, airports, stations, landscapes, video walls, civilbuildings, indoor partitions, stages, sanatoria, dymnasia, playgrounds, apartments, private cruise sjips and so on which require beatifying, being a popular novel decorative materials in modern internation market.
