Energy saving - glass block façades evolve
As a result of its continuous efforts to safeguard the environment and promote the conservation of energy, Seves has reset the U-value limits for the thermal transmittance of glass with a new technology that modifies the reflective and transmitting properties of the glass block, without altering its mechanical and chemical characteristics.
This new patented technology effectively reduces the thermal transmittance of the glass block by up to 50%, a dramatic reduction which makes glass block facades a more eco-friendly architectural solution than ever before. This innovation is made possible by the introduction of a low-emissivity glass plate, which interrupts the thermal bridge between the two halves of the glass block, and through the injection of pressure controlled argon gas, which reduces the thermal transmission caused by convective motion.
Now, using ‘Energy Saving’ technology a classic Seves design such as the renowned Pegasus 19 x19x8cm glass block can reach a thermal transmittance value of U=1.5 W/m²K, offering new possibilities to architects and building professionals focused on long-term sustainability.
The new ‘Energy Saving’ glass blocks have been subjected to the following laboratory tests in addition to the standard tests required to obtain CE certification in accordance with norm UNI EN 1051-2.
- Compressive strength test on the bearing surface of the glass block in accordance with norm EN 1051/1:2005
- Thermal endurance test in accordance with norm EN 1051/2:2008
- G-Value calculation in accordance with norm EN 410:2000
- U-Value calculation in accordance with norm EN 673:2005
- Sound insulation test in accordance with norm EN ISO 717/1:2007
All values are certified by international laboratories, and a copy of the relative certification can be requested from Shackerley.
