Thermal efficiency continues to shape how modern buildings are designed, with architects and specifiers seeking insulation solutions that deliver strong performance without adding unnecessary bulk to wall or roof assemblies.
Masons’ PrimeTherm ERS PIR Insulation Board has been developed as a rigid insulation option designed to provide high thermal performance across a wide range of construction applications. The board delivers a high R-value per millimetre, allowing designers to achieve effective thermal insulation while maintaining usable internal space within wall and roof systems.
The insulation board can be used across multiple building elements including walls, ceilings, roofs and under-slab applications. In wall systems it can improve thermal performance without significantly increasing wall thickness and is compatible with a variety of cladding types. In roof and ceiling applications it helps maintain consistent indoor temperatures while reducing heat loss and condensation risk. Under-slab installation can also contribute to improved comfort and energy performance within the finished building.
PrimeTherm ERS PIR boards are lightweight and durable, supporting easier handling and installation on site. The product is designed to meet New Zealand Building Code requirements and is available in multiple board sizes, thicknesses and facing options to suit different construction methods and project types.
The ERS designation stands for Energy Return System, reflecting the role effective insulation plays in reducing energy demand and improving long-term building performance.
