DuPont™ SentryGlas® –
11 Years On and Still Going Strong
Endesa Headquarters, Madrid, Spain
The 113 x 36 m roof of the Endesa headquarters in Madrid, Spain, comprises an almost horizontal flat glass surface composed of 861 point-fixed laminated glass panes, with a total area of approximately 3,150 m2. The glass panels, which vary in shape and size depending on their location, all feature a three-layer construction, consisting of 8 mm heat-soaked fully-tempered SLS glass top and bottom plies, sandwiching a 2.28 mm
(90 mil) SentryGlas® interlayer fixed with four-point fixations and a silicone sealing between the panels.

Designed by Kohn Pedersen Fox Associates (KPF) and engineered and built by Bellapart s.a.u. between May 2001 and June 2003, the atrium roof and façades of the Endesa Headquarters in Madrid, Spain, underwent inspection and testing to check for any degradation in the glazing.
The testing and lamination quality check involved removing an 11-year-old glass pane from the roof and then subjecting it to a thorough visual inspection prior to performing a pummel test.
The pummel test – a test used on a regular basis by laminators to evaluate adhesion – was then performed on an area adjacent to a glass vertex, as it is the area most exposed to moisture ingress and degradation.
