Fire Rated Mailboxes - Two Hour integrity

An overview of the new range of Fire Rated Mailboxes with Two Hour Integrity. FR1, FR2 & FR3, three fire rated mailbox models had already been tested by Warrington Fire to the previous BS 476 Part 22: 1987 standard, which meant that they had all achieved a 60-minute fire rating. We wanted to extend the test to 2 hours to ensure that the area commonly used as an evacuation point was capable of holding back a fire or containing a fire. To achieve this, we sent our fire rated mailboxes to Warrington Fire for a 120-minute integrity only test. In October 2019 and October 2020 we tested these mailboxes at Warrington Fire as singles and as banks in order to see exactly how they would perform in a fire situation. On both occasions they passed the 2 hour test with no failures.
