Project Description

Challenge: Largest structural sealing project – 250 meters

Project: Torre Caja – Madrid, Spain (Norman Foster & Partners)
Products: REFORAC 933 AND 400 NEUTRAL SILICONE SEALANT

The Torre Caja in Madrid [the tower of the Bank of Madrid], is located in the complex called CTBA (Four Towers Business Area) of Madrid; at a height of 250 meters, it is the tallest skyscraper in Spain and the fifth tallest in Europe. The steel construction of the building weighs 11,000 tons, the façade is covered with glass and stainless steel plates in concrete cores. The following sealants were used for sealing between the joints of these elements and making them watertight: 400 and 933. There are 45 floors, and at the top of the building there is an empty space under the upper part which is designed to accommodate wind turbines as a possible innovation in the future.
