Fire Shutters
Guardian offer nationwide installation of their range of fire shutters. Fire shutters are made to the latest British and European safety standards and CE marked accordingly. We offer a range of control options for the activation of the fire shutters in the event of a fire as well as normal every day opening and closing.
Explanation of Fire Rating Symbols
| Integrity & Insulation | |
| E - Integrity | This is the ability of a test component to stop fire from spreading to an unexposed side as a result of penetration of flames or smoke. |
| I - Insulation | This is the ability of a test component to restrict the temperature rise of the non-heated side to below specified levels during the fire, which is not more than +140°C up to +180°C. |
| Integrity & Radiation Reduction | |
| E - Integrity | This is the ability of a test component to stop fire from spreading to an unexposed side as a result of penetration of flames or smoke. |
| W – Reduction of thermal radiation | This is the ability of a test component to resist fire exposure on one side only, so as to reduce the probability of the transmission of fire as a result of significant radiated heat either through the element or from its unexposed surface to neighbouring objects. |
All of the above parameters are followed by a time limit in minutes. The number after a given symbol shows the time the performance criteria is fulfilled during a standardised fire test, eg. EI120, EW60, etc.
