Kishoge Primary School in Lucan, Co. Dublin demonstrates how Modern Methods of Construction can support the delivery of high-performance, permanent education buildings at speed, while maintaining strict quality and energy standards.

The project comprises a 3,600 sqm, two-storey school delivered using an Enhanced 3D Volumetric Modular approach—marking the first application of this system in Ireland’s education sector. Completed in approximately 72 weeks from design through to delivery, the programme represents a significant reduction compared with traditional construction timelines, while maintaining full compliance with performance requirements.

Manufactured offsite using Light Gauge Steel (LGS) framing, the building consists of 152 fully fitted volumetric modules. This approach enabled parallel progress across design, manufacture and site works, reducing programme risk and supporting earlier occupation.

As an MMC Ireland member, Partel played a key role in the project’s building envelope strategy, providing technical guidance, condensation risk analysis and quality assurance support to ensure that performance targets were achieved across both factory and site conditions. The project required particular focus on airtightness at modular scale, where junctions, interfaces and transportation constraints introduce additional complexity.

To meet air permeability targets, IZOPERM PLUS was specified as the internal Vapour Control Layer (VCL), installed within the LGS frame to ensure continuity of the airtight layer. Externally, EXOPERM MONO SA 250—a self-adhered breather membrane—was applied directly to the sheathing board. This approach eliminated the need for mechanical fixing, enabling faster installation, reducing labour requirements and minimising the risk of damage during transport, a known challenge in offsite delivery.

Airtight continuity across interfaces was further supported through the use of sealing tapes, ensuring robust detailing at critical junctions including windows, doors and membrane overlaps. In parallel, Partel carried out U-value calculations and hygrothermal assessments to verify that the envelope design aligned with Irish climate conditions and long-term moisture performance requirements.

The result is a highly airtight, energy-efficient building envelope that supports operational performance over the building lifecycle while maintaining durability and constructability within a modular system.
