Description

The sports complex, built in 1967, had already hosted suspense-packed competitions at the Summer Olympic

Games in 1968 as well as being the venue for the FIFA World Cup in 1970 and 1986. The stadium was completely

modernized in the years 2014/2015 and furnished with the first ETFE façade in Mexico by Dünn Lightweight

Architecture.

The façade seems extremely lightweight in its curved shaped and incorporates pre-Columbian design elements

with its mosaic character. It consists of 124 vertical segments, about 40m in height. A total of 5.952 ETFE film

sections in the three shades were welded to one another for the segments.

In the daytime the club colors of blue and white as well as the transparent sections continue to be visible. By night

the film sections are illuminated in various colors by LED lights.

Especially important in the hot and humid climate: In the production of films made of 3M Dyneon ETFE no

plasticizers are required, which evaporate over time and thus could promote algae or fungal growth. ETFE films are

so smooth that rain showers are sufficient to clean the façade to the greatest possible extent. They are so resistant

to other chemicals that they are also able to withstand environmental influences such as exhaust emissions for

decades. Originally, parts of the façade of the stadium in Puebla were made of glass panels in various colors. Dünn

Lightweight Architecture chose to design the complete façade with ETFE film instead. One significant advantage:

The weight per unit area of ETFE is around 95% lower than that of glass. As a result, stress analyse were able to

build the supporting structure in a much lighter way. Instead of the 2.500tons of ste
