ADVANCED INTERLAYER SOLUTIONS
Located on the Avenue Insurgentes, on the corner of Río Mixcoac, in southern Mexico City, the new Manacar shopping mall sits on the site of the old Cine Manacar, which closed its doors in 2013.
Co-located with the Torre Manacar or Manacar Tower, this hugely impressive complex − which has been awarded Project of the Year 2018 in the Building category by Mexican Magazine ‘Obras’ − measures some 180,000 m2 (1,900,000 ft2). Opened in 2017, the mall comprises a mixture of commercial enterprises, including shops, restaurants and a new cinema, with parking for up to 2,700 vehicles. Designed by renowned multiple-award-winning architect Teodoro González de León, who sadly died in 2016, the mall makes incredible use of glass to deliver uninterrupted views throughout the complex, thanks to its use of balustrades. But the most striking glazed feature is the egg-shaped skylight in the roof, which has been fabricated using multiple shaped panels, to create a slightly domed effect, which lets in as much natural light as possible.
Over 2,600 m2 (21,500 ft2) of glazing − at height and in public areas − required the deployment of laminated panels to provide strength and post-breakage performance and, for these features, Trosifol® Clear PVB and SentryGlas® ionoplast interlayers were used in their construction.
The balustrades are made up of two 10 mm (0.4 in) fully tempered (FT) glass panels sandwiching a 1.52 mm (60 mil) SentryGlas® interlayer. The skylight’s 644 triangular and rectangular facets are fabricated from two laminated panels on either side of a 12 mm (0.47 in) air gap, with each panel comprising two 6 mm (0.24 in) FT glass panes sandwiching a 1.14 mm (45 mil) Trosifol® Clear PVB interlayer.
According to architect Hatumi Hirano Beltran, Project Manager at TGL Arquitectos and Andres Lelo de Larrea, a consultant from HEG: “Glazing was very important for this project, as Teodoro Gonzalez de Leon prioritised the use of glass in his designs, with the aim of fusing the building with the environment and letting as much natural light inside as possible. From the inside, the façade glass delivers transparency, while from the exterior a slight reflectance is perceived in grey tones. Large-format panels were deployed to maximise the sense of spaciousness and achieve the maximum use of natural light.
