This certification, granted by the National Standards Authority of Ireland (NSAI) Agrément, recognises that our modular building system has been rigorously assessed and confirmed as compliant with the current Irish Building Regulations, demonstrating that it is fit for purpose, durable, and suitable for use under Irish site conditions.
