Fire Rated Access Panels & Overboxes

Gas and electric meters are essential. But it’s often the case that their contents not only make them a potential fire threat, but also compromise the fire rating of the wall the meter itself is installed on. If a fire were to break out within the meter, a fire-rated meter overbox will contain it. Similarly, if a fire were to break out near to the meter, the overbox would protect it from damage, thanks to the toughened construction and intumescent seals.

Here at Fire Protection Online, we offer a range of access panels and overboxes, with something suitable for most requirements. We can also get access panels and overboxes custom-made for your exact requirements, so do get in touch for more information about this service.

  • What makes an access panel or overbox fire rated?

    Access panels and overboxes are considered fire rated if they do not combust for a certain period of time during a fire. For example, if an access panel was said to have a fire rating of two hours, this would mean it could withstand a fire for two hours before combusting.

  • How to install access panels and overboxes

    When installing fire-rated access panels and overboxes, it is very important that they are fitted properly. To be fire-rated, the panel or overbox must be completely flush, so a seal is created which prevents fire or smoke from entering or exiting.

    If you are not confident fitting your access panel or overbox, we recommend that you enlist a professional to do it for you.
