Opened in 1998, the WTC Montevideo is a 5-tower complex, the most recent being the WTC FREE ZONE. This last one has been developed with the latest technology and designed as an open space in order to allow maximum flexibility to create new rooms. In addition to being an intelligent building, it is also the only building in Uruguay having the LEED Certificate. In the public areas of the WTC FREE ZONE we have installed 3.500 square meters of raised floor panels made of calcium sulphate core and top finish in porcelain tile. Petral has also installed its panels in 46 offices of three other towers, headquarters of prestigious international companies who have chosen different types of materials for a total of over 5.000 square meters.
