High-performance membranes prove a safe choice for the Dean Hotel


3rd December 2020

High performance membranes from the A. Proctor Group have been selected in theconstruction of the new Dean Hotel in Cork, Ireland. The 114 bed hotel with rooftop restaurant is just part of an impressive major rejuvenation scheme across a 6 acre site at Horgan’s Quay, which will include apartments, offices, bars, and restaurants.

The Dean Hotel has been designed by the award winning practice Wilson Architecture, with BAM Ireland as the main contractor for the project. Specialist roofing and cladding contractor Deane Roofing and Cladding were appointed for the façade works.

A key requirement was to produce an 8-storey building which meets the highest standards in terms of fire, acoustic and thermal performance.

Instead of using a traditional internal air barrier, Wraptite, a self adhesive, vapour permeable, airtight membrane, was applied externally, quickly and easily as part of the rainscreen system.

Project architect, Shane Kerrisk explains, “Wraptite was chosen for the ease with which it could be fixed, and for its provision of a watertight line when used as part of the Kingspan K-Roc Rainscreen System, and its performance in relation to fire. It also removed the requirement to tape and joint the substrate.”

Wraptite is the only self-adhering vapour permeable air barrier certified by the BBA and combines the important properties of vapour permeability and airtightness in one selfadhering membrane. Whilst internal air barriers will need to accommodate building services such as electrical, lighting, heating and drainage systems, Wraptite is an external air barrier, allowing for an almost penetration-free airtight layer which can be installed faster and more robustly. Wraptite fully bonds to virtually any substrate, requiring no mechanical attachment, seals or tapes to suppress air leakage around junctions or penetrations.

In addition to the Wraptite air barrier membrane, Procheck FR200 was selected as a fire retardant vapour control layer on the project.

Procheck FR200 has a Reaction to Fire classification of B, s1 –d0 according to the Euroclass system, which provides assurance of fire performance for the structure. Procheck FR200 is an air and vapour tight membrane which will improve energy efficiency and reduces the condensation risk.
