Cementitious Vermiculite Textured Finish Surface
The cementitious vermiculite spray applied fireproofing is a light weight texture spray. The lighter weight coating is better, as it has less loading onto the building structures. The spray applied textured finish can be seen as follows.
Cementitious vermiculite fireproofing is generally rough textured finish and in natural cement colour. The cementitious vermiculite fireproofing is a lightweight coating when compared to reinforced concrete. Therefore the light weight properties is an advantage of using cementitious vermiculite fireproofing in building high rise structures.
Using cementitious vermiculite fireproofing as a passive fire protection, it extends the time for structural steel to retain its integrity and stability during the rising temperatures of cellulosic fire or hydrocarbon fire. Without the cementitious vermiculite fireproofing protection, the bare steel will quickly attain high temperature and lose its structural load bearing functions. Therefore the light weight properties provide fireproofing function and does not add to the loading on structural steel.
As cementitious vermiculite fireproofing is generally lower costs than intumescent paint, it is often favoured for costing considerations. However due to aesthetic requirements, it is common for both intumescent paint and cementitious vermiculite fireproofing to be provided together in the same project.
