Seves glassblock presents the innovative “Energy Saving” technology that halves the thermal transmittance of the classic glass block.
This innovative “energy saving” technology allows the glass block to reach a thermal transmission value of 0,7 W/m2k. This important new development makes it possible to design buildings made completely of glass blocks. New energy saving glass blocks Always attentive to safeguarding and protecting the environment and to saving energy, Seves Glassblock has achieved an important goal in glass architecture with the introduction of a more sustainable and eco-friendly solution.
The definition of a new philosophy in the production process has allowed Seves Glassblock, a world leader in the manufacturing of glass blocks, to perfect a new technology that improves the performances relating to the reflection and transmission of solar energy in the glass block, without altering its mechanical and chemical characteristics.
As a result, the new ENERGY SAVING technology makes it possible for a glass block, e.g. the Pegasus 19x19x8cm, to reach a thermal transmittance value of 0.7 W/m2k compared to the standard value of 2.8 W/m2k.
The classic glass block is made up of two half-shells containing air without humidity. This system is comparable to a system made up of two floating glass sheets joined together with the interposition of a “chamber” containing air without humidity.
The new “Energy Saving” system patented by Seves develops the principle of “chambers”.
The system puts a sheet of floating glass between the two halves of the block. This sheet is characterized by low emissivity. In this way, two “chambers” are created and the space enclosed in them no longer contains air, but Argon gas. As a result, the glass surfaces increase from two to three and the combined effect of the “low emissive” glass sheet. The new ENERGY SAVING glass blocks were subjected to the tests necessary for obtaining the CE mark in compliance with the UNI EN 1051-1 and 1051-2 standards, as well as the following laboratory tests:
- Resistance to compression along the side of the block in
accordance with the EN 1051/1 2005 standard;
- Resistance to thermal shock in accordance with the EN 1051/2 2008 standard;
- Evaluation of the solar characteristics, EN 410 2000;
- Calculation of the U-Value, EN 673 2005;
- Acoustic insulation, EN 7117/1 2007.eet, the Argon and the three glass surfaces allows considerably reducing the block’s thermal transmittance value
