Sealants from Dowsil, including its Firestop 700 were specified for use on the atrium elevations and glazed partitioning in The Sorting Office, a new commercial property in Dublin’s Silicon Docks district.
The seven storey office building was developed by Martlet Property Group and designed by Henry J Lyons Architects. Walls Construction Ltd. was the main contractor, with sub-contractor Walls to Workstations (W2W) helping to create the development’s light-filled central atrium space.
W2W installed glass elevations totalling 1,944 m2 in area around all seven floors of the atrium using a variety of Dowsil glazing sealants. The highest specification product selected was Dowsil Firestop 700 low modulus sealant in Black, which was required for the top two floors. On these levels, an Optima Technishield 65 system was used, glazed with Pyroguard EI 30-32-2 SWS glass and featuring mitred corners to avoid having to include metal posts at the edges. The completed installation achieves a barrier load rating of 1.5 kN/m.
All the sealant products were specified and distributed by the Sherwin Williams Company.
The Specialist Works Contract Manager for W2W, Peter Durand, said: “W2W were awarded this project due to our ability to meet the required performance specifications whilst maintaining the design intent. The Pyroguard glass was originally tested with a light glazed product which we really didn’t like, as it presented a grainy appearance.”
Unlike the top two floors, the first to fourth floors of the atrium did not require fire rated glazing. These partitions were assembled using Dowsil 895 Black Structural Glazing Sealant, again achieving a load rating of 1.5 kN/m.
On the ground floor, W2W was also responsible for creating the three-sided enclosures to the scenic lifts, which have a total area of 33m2 and use the same glass specification as the lower levels of the atrium, including the use of Dowsil 895 Structural Glazing Sealant in Black.
