Restoration of UNESCO World Heritage Site Brú na Bóinne Museum

The Brú na Bóinne World Heritage Site, nestled within a bend of the River Boyne in Ireland, is one of the world’s most remarkable Neolithic landscapes. It is celebrated for its ancient passage tombs—Knowth, Newgrange, and Dowth—constructed around 3200 BC. These monumental structures, renowned for their ceremonial significance, hold the largest collection of megalithic art in Western Europe, making Brú na Bóinne an archaeological treasure and a pivotal site in the study of early human civilization.

During its recent restoration, Diathonite Evolution thermal plaster was selected to address both insulation and preservation needs, aligning with the museum’s heritage and environmental priorities. This natural, cork-based plaster was applied across exterior and interior surfaces to enhance thermal insulation and breathability, which are essential in protecting the building's structure from Ireland's damp climate while maintaining energy efficiency.

Products Used and Application:

Diathonite Evolution: This eco-friendly, cork-based plaster offers high thermal resistance and moisture regulation, making it ideal for historic structures needing both protection and climate control. Applied in layers, it maintains the building's integrity while providing effective insulation.

Watstop: Applied as a waterproofing barrier to shield the museum’s structure from rising damp and groundwater intrusion.

Limepaint: A breathable, mineral-based finish used for its aesthetic and protective qualities, harmonizing with the museum’s heritage architecture.

Each product was selected to support the museum’s long-term sustainability goals, enabling effective climate control without compromising historical integrity.
