Introduction Energy saving: The building of a ‘ greener ’ tomorrow starts today with the choice of smart materials. Resistance: Protect all the buildings from fire with fireproof glass bricks. Safety: For all those applications which need a high safety level. Insulation: Create a more comfortable and functional environment with glass bricks insulation properties.
Introduction Privacy: Even where there is a need for privacy, there is a need for natural light. Design: A definition of space with a harmonic combination of colours, light, shapes and textures. Tailor made: The most prestigious projects realised in glass bricks.
The glass block Pegasus glass blocks reduce the thermal transmittance of the classic glass block up to 50% • creating architectural façades made entirely of glass blocks that promote the conservation of energy and safeguards the environment • introduction of a low-emissivity glass plate and pressure controlled argon gas • can reach a thermal transmittance value of U=1.5 W/m² K . • CE certification in accordance with norm UNI EN 1051-2: – Resistance to compression along the side of the block according to the EN 1051/1 2005 standards; – Resistance to thermal shock according to the EN 1051/2 2008 standards; – Evaluation of the solar characteristics, according to the EN 410 2000 standards; – Calculation of the U-value according to the EN 673 2005 standards; – Sound insulation according to the EN 7117/1 2007 standards.
Technical information thermal insulation - the “thermal bridges” created by gaps between glass bricks are reduced compressive strength - only excellent quality raw materials and a manufacturing process that dedicates special attention to sealing and annealing can guarantee high compressive strength in glass blocks thermal endurance - thermal shock is one of the most stringent tests that glass bricks must undergo to verify their strength and resistance light transmission - transparency, one of the most important features of glass bricks, creates different effects in relation to the many possible combinations that can be made using different patterns, shapes, finishes and colours sound insulation - features such as mass and the internal air space guarantee that glass bricks offer a high level of sound insulation, even superior to that of brick walls of identical thickness fire resistance and reaction - glass, by its nature, tends to break quickly when subjected to thermal shock, glass brick structures offer a good level of safety - they constitute an effective fire barrier internal pressure - the pressure inside glass bricks is lower than the atmospheric pressure - in the event of breakage, the glass fragments tend to converge towards the inside (implosion) of the glass blocks instead of being projected outwards (explosion)

Notes regarding installation Expansion joints The expansion joint is necessary for correctly installing glass blocks and it must be placed on lateral (sides) and upper edge in order to prevent possible settling of new structures from transmitting vibrations and damaging the glass blocks.
Galvanised steel rods • The wall must be reinforced in vertical and horizontal joints to guarantee higher stability and safety. • Rods shall not be welded, because this would create a too ridged structure and damage the glass part.

Glass block range Patented by Seves, ENERGY SAVING effectively reduces the thermal transmittance of the glass block up to 50%, with the introduction of a low-emissivity glass plate and pressure controlled argon gas . The glass plate is inserted between the glass block halves to interrupt the thermal bridge, while the argon gas is added to reduce the thermal transmission caused by convective motion. This makes it possible to create architectural façades made entirely of glass blocks that promote the conservation of energy and safeguard the environment.
