Dens Glass Complete

With the exception of a few pieces the Dens Glass work is completed on the entire building. Waterproofing membrane – seen below in blue – is virtually complete on the Eastside of the building as well as the South end area of the cantilever.

This self- adhering, rubberized material is completely water proof. In certain locations, such as around the windows, there is added adhesion, a contact cement, that is rolled on to the window sill and below, so that the membrane doesn’t blister.

A grid system of aluminium strips will be installed on the wall to hang the panels and to ensure that the reveal joints are aligned. Fastening clips, which are screwed through the Dens Glass will also be installed as part of the grid system.

The Alucabond panels are being fabricated at the Sunrise Erectors shop in Canton, MA by members of Carpenters Local 51. The panels arrive to the shop 5x10 sheets, which are cut to specifications and fastening clips are installed.

When the panels arrive at the Carpenters Center they will be installed using a process known as ‘blind fastening.’ The panel clips are matched up with the clips that were installed into the aluminum grid system for fastening. This process requires that each panel be matched up to a specific location throughout the building. Carpenters installing the panels will read numbers on back of the panel so they know where each goes.
