Assa Abloy - Sargent Manufacturing and Corbin Russwin


Assa Abloy Group is an international company specializing in locks and security solutions.  Located in Sweden, Assa Abloy grew quickly through the acquisitions of numerous manufacturing companies throughout the world.  In America, these companies include Sargent and Corbin Russwin, both acquired in 1996.  Combined, these two facilities have over 1,000,000 square feet of roofing.

As part of Sargent’s regular ongoing maintenance program, the company continued to retain the services of Martin A. Benassi, AIA - Architect LLC to produce construction documents for sections to be reroofed with a fully adhered 60 mil EPDM membrane system over tapered rigid insulation, adhered to light-weight cementitious decking. 

At Corbin Russwin, sections of existing CPE (Chlorinated Polyethylene) thermoplastic single-ply membrane assembly have been replaced on a priority basis, in accordance with the Contract Documents produced by Martin A. Benassi, AIA - Architect, LLC.  Our firm also provided field supervision of the work.  The owner’s goal is to replace all of the existing roofing material over the coming years.  The new roofing assembly consists of rigid insulation boards fastened to the metal deck and a fully adhered 60 mil EPDM membrane system.

Both roofing systems met the owner's requirements within a tight budget while conforming to a limited weight factor and extreme time constraints, as well as meeting FM Global’s wind uplift ratings.
