Comprehensive Fire Rated Testing

The fire rating test involved removing the backs of the parcel boxes to simulate a fire inside and at the rear. Next, the boxes were placed in a furnace reaching temperatures of 1,064°C. After 132 minutes, our myRENZbox parcel boxes showed no signs of weakness or deterioration, successfully passing the test. As a result, they now carry a 2-hour fire rating, fully compliant with the BS EN 1363-1:2012 standard.

Furthermore, as a trusted British manufacturer, we provide expert safety guidance on the correct use and installation of fire-rated parcel boxes within fire-rated walls. In addition, our team offers comprehensive advice and support to ensure proper handling and installation on-site, prioritising safety and compliance at every step.

Working with Warrington Fire

The Safety Letterbox Company R&D team collaborated with Warringtonfire, becoming the first company to achieve a full 2-hour Fire Rating (integrity only), tested to BS EN 1363-1:2012. As a result, both parcel boxes and mailboxes can be safely installed within fire-rated areas, walls, or escape routes, provided the appropriate guidelines are followed.*
