Dowsil and Geocel sealant products were selected for use on the cladding of The Exchange Building in Dublin’s financial district.

Cosgrove Properties led the project as developer for IPUT Real Estate, the largest owner of offices in Dublin, with Sisk as main contractor and KMD Architecture heading up the design team.

As part of the development, a comprehensive curtain wall and stone cladding package was designed, manufactured and installed by Alucraft. This package made use of a range of high-performance sealant products, such as Dowsil 791 Weatherproofing Sealant and 993 Structural Glazing Sealant, all supplied by The Sherwin Williams Company, with Alucraft’s installation sub-contractor supplying natural stone elements for part of the façade where Geocel 925 NS features.

Along with routine logistical support for the contractors, Sherwin Williams’ Technical Sales Manager for Ireland, Adrian Flynn, provided data on existing accreditations and also data from testing carried out specific to the project’s unique requirements. This included stone compatibility testing to establish that the sealants would not cause any staining to the stone cladding chosen. 

The Exchange Building’s exterior envelope uses a complex combination of stone cladding, sloped atrium glazing and stick-build, as well as unitised curtain walling, all weatherproofed using Dowsil 791.

The Exchange Building has been built to a Grade A standard, with an A3 energy rating, as well as a LEED Gold environmental standard. Work commenced on the 107,500 sq ft six-storey office building in 2016 and was completed in 2017. The lead tenants include Walkers Global, A&L Goodbody, Partner Reinsurance Europe SE, and The Food Safety Authority of Ireland. There is also a 1,200 sq ft retail unit fronting onto George’s Dock and a smaller (500 sq ft) shop on Common Street.
