Madrid, Dec 12 (EFE). - The Bernabéu stadium has 300 access doors, each weighing 70-80 kg of steel. Durability of up to 100 years. This is part of a noise reduction project in which Real Madrid is working. On the other hand, steel solutions provide a high level of security, with 60 minutes of fire resistance - preventing the spread of fire and temperature - and with certificates reaching RC4 (anti-theft) and FB6 (bulletproof) classes. In addition to the Bernabéu, Jansen, founded in Switzerland in 1923 and present in Spain since 1998, also participated in the renovation of another major Spanish football stadium: the Spotify Camp Nou project, with 60 units of doors and 60 m2 in fixed side sections. These were implemented, above all, in the players' tunnel to the field, acting as thermal, fireproof, and acoustic insulators, with the objective of making the pre-match talks less audible, the company points out. Another of its great projects, outside of sports, is the Sagrada Familia, in which they have carried out "thousands of carpentries." "We register each steel melt from which each window was manufactured. In case there was any problem, the composition of that specific steel could be identified," points out Jorge García. Jorge García, director of Jansen Iberia, the company behind the steel solutions, also present at Camp Nou, the Sagrada Familia, or the Prado Museum, among others, explains the secrets to EFE. Steel, 25% more insulating than aluminum, allows energy expenditure for air conditioning to be reduced by 5% to 15%, a strategic saving in the sports infrastructure business. It also means savings in its manufacturing and maintenance. In the case of steel, the joints are welded. In aluminum and PVC, they are mechanical joints that, with use, become misaligned and generate friction. "No matter how much time passes, it is not going to get misaligned," he states. Steel solutions that also "soundproof a very wide percentage of acoustic pollution," being able to reach attenuations of 40 to 42 decibels if worked in conjunction with acoustic glass. However, with the aluminum solution, up to six times less energy and 20-25% less water are consumed. More than 400 units if including VIP boxes, sky bar, control and information areas. Fire-resistant, bulletproof, and with acoustic insulation in a material that can achieve attenuations of 42 decibels. For this reason, Jorge García defends the bet on steel solutions, which can be recycled infinitely without losing properties. "In sustainability, laboratories measure a parameter called LCA (Life Cycle Assessment), which evaluates the useful life. In the case of steel, it can reach 100 years," he points out. Steel is melted at a temperature of 1,500 degrees Celsius. Factors that reduce the carbon footprint and total cost of ownership for clubs. Sustainability is a key factor in the construction and renovation of stadiums.
