Enclosure Features
The following values of resistance to air, water, wind load, noise, and thermal transmittance allow us to contrast the level of quality that has been maintained in the design and construction of the building, specifically in the protection of the envelope (façades and windows). The insulation achieved is well above what is established by regulations, and this allows it to obtain LEED credits that have to do with energy efficiency.
- Air permeability according to the UNE-EN 12207 standard: Class 4 , this being the one with the greatest tightness, and indicating that the windows are of maximum airtightness and quality.
- Water tightness according to the UNE-EN 12208 standard: Class E 1200 , which again corresponds to the windows with the highest level of watertightness.
- Wind load resistance according to UNE-EN 12210 standard: Class C5 , with the capacity to withstand pressures greater than 2,000 Pascals and wind speeds greater than 206 kilometers per hour.
As a curiosity, it is worth mentioning that the highest wind gust recorded in Madrid occurred on March 13, 1951 at 9:20 a.m., with a speed of 115.92 kilometers per hour. - Noise protection:
- Airborne noise insulation: Ra = 33.9 ± 1.2 dBA
- Weighted sound reduction index: Rw = 35 (-2; -4) dB
- Thermal transmission: Uw= 3.0 W/m²K
