Ahead of our 25th anniversary exhibition opening night, we’re showcasing case studies by some of our members. The A Proctor Group has, for nearly 50 years, been serving the construction industry with an extensive portfolio of technically advanced thermal, acoustic and membrane products. Join us at the opening night of our new exhibition to see more case studies from A Proctor Group and other Green Register members.

Piper’s Square in Charlestown, Dublin is one of four projects currently under construction by Cairn Homes, Ireland’s largest house builder. Alongside the other three sites, Pipers Square represents the company’s first foray into delivering residential accommodation to the Passivhaus standard. Over 1700 units are expected to be delivered by the first half of 2026, with some 600 units of those ready to occupy at Pipers Square by the end of 2025. 

The A. Proctor Group’s external air barrier, Wraptite®, is part of the external wall specification at Pipers Square. In addition, the Group’s technical services team assisted Cairn Homes with U-value calculations, and a condensation risk analysis to explore the effect of vapour permeable insulation.
