The Framemaster letterplate is lined with special intumescent material which expands to 50 times its size, blocking the hole in the cavity and preventing smoke coming through the cavity. The intumescent is activated at 5 degrees lower than most other intumescent material in the market, meaning that the cavity will be blocked quicker. The letterplate also uses special heat absorbers which stops the screws, once they are red hot, melting the plastic around then and causing the letterbox to fall off.

The Framemaster letterplate is compliant to BS EN1634-3:2004 smoke leakage regulations.

On the UAP Framemaster 12 inch letterplate there are many features that are not found on standard letterboxes. This includes the trademarked Anti-Vandal facility. Each year house fires are started by vandals putting fireworks through letterboxes. Each UAP Anti-Vandal letterplate has the brushes outward facing (a feature no other letterplate in the industry has). This gives 3 great benefits:

1 – Having brushes on the front of the door acts as a visual deterrent to vandals. As the internal cavity is not easily accessible, it makes it a lot harder to put lit fireworks etc. into the cavity.

2 – It is easier for postmen to navigate letters through the brushes, so you won’t end up receiving crinkled letters anymore.

3 – The brushes stop draughts at the point of entry, making the letterplate draught-proof.

Another great feature of all UAP letterplates is that each letterplate flap can open to 180 degrees, meaning that it should not snap, and making letterplate flaps snapping off a thing of the past. Many letterplates in the industry only open to 90 degrees, so when too much force is applied when lifting the flap up, it causes them to snap off. The ultra-flexible springs means that they can withstand thousands of openings without breaking, making them last even longer. Also, an internal water seal also prevents water getting into the door or panel, which stops letters getting wet as they are posted through, and also helps to prevent the flaps from pitting or rusting.
