Isteel’s Fire Rated range was developed to meet a demand for attractive looking Fire Rated products that are not only functional, but also desirable.
All iSteel Fire Rated solutions are 100% tested and certified, ranging from 30 minutes to 120 minutes protection, depending on the level you require, stipulated by Building Control.
Upon installation, iSteel will issue you with certification which you can present to Building Control for sign off.
Fire Ratings Explained
iSteel specialise in Glazed Steel products, which is why we offer ‘E’ and ‘Ei’ Fire Rated solutions rather than ‘FD’ which relates to Timber.
– ‘E’ and ‘Ei’ ratings represent products such as Steel, Aluminium and Glass which are conducters of heat.
– ‘FD’ ratings represent products such as Timber which are non-conductors of heat
Both ‘E’ and ‘FD’ ratings are comparable, suitable for most situations and equally compliant with building regulations. The terminology is a little different to identify the material make up for a specific product.
To ensure that the correct product is quoted for and ultimately installed, we recommend presenting our downloadable ‘Fire Classifications Sheet’ to your local Building Control for confirmation of Fire Rating level your project requires.
Understanding Fire Ratings
‘E’ (Integrity Only)
Integrity Only Fire Rating refers to the length of time the product will prevent the passage of flames from transferring from the fire side, but offers no protection against heat.
An ‘E’ rating is followed by a number, which indicates the number of minutes the product will sustain protection for.
Typical ‘E’ Ratings
E30 (30/0) = 30 minutes
E60 (60/0) = 60 minutes
E90 (90/0) = 90 minutes
E120 (120/0) = 120 minutes
‘Ei’ (Integrity & Insulation)
Integrity & Insulation Fire Rating refers to the length of time the product will prevent the passage of flames, smoke and heat from transferring from the fire side.
An ‘Ei’ rating is followed by a number, which indicates the number of minutes the product will sustain protection for.
Typical ‘Ei’ Ratings
Ei30 (30/30) = 30 minutes
Ei60 (60/60) = 60 minutes
Ei90 (90/90) = 90 minutes
Ei120 (120/120) = 120 minutes
