ProFinish were given the task to fire rate all structural steel throughout the building. This was achieved by using a multi system including Cafco300 and Promatect 250 board.
The Cafco300 was applied to all the structural beams, whereas, the Promatect 250 board was fixed to all the structural columns. These two methods both allow for desired FRL needed for the job and have their own perks. Vermiculite (cafco300) is typically a cost-effective option and can be simply applied by a spray machine.
Vermiculite cannot be fixed into as the product is brittle and chips away. Whereas, the Promatect Board is often a preferred choice by architects for columns as the board is designed to be fixed into which makes the framing process of a job simpler.
