New Prefab Collaboration from Resene Construction Systems and Concision

Resene Construction Systems has worked closely with the Concision team for the past two years in developing a cavity based external facade system that can be constructed off site, then transported, assembled and finished on site. The facade system development included multiple specially developed designs, techniques and processes specific to Concision.

Key benefits to the off-site construction process were no weather delays, clean accessible work areas, and accuracy of system installation.

Resene Construction Systems' Integra AAC lightweight concrete system was selected as part of the facade system as minimal componentry is required. The Integra system also has acoustic and impact-resistant advantages over other systems. The Integra system combines Resene Construction Systems' patented EdgeSeal flashings, alongside the exclusive Rockcote reinforced plaster system, and Resene paint and colour technology that provides surety of durability and performance from climatic extremes for the life of the building.

Significant quality controls are in place throughout the entire process to ensure best practice is adhered to across all disciplines and stages. The Concision process is highly monitored and robust to ensure optimal panellised production outputs.
