Mila launches a fire rated version of its SupaStyle stainless steel letterbox

Mila is launching a fire rated version of its SupaStyle stainless steel letterbox making it an ideal choice for customers fabricating and installing fire doors. The new letterbox has a high performance intumescent liner around the sleeve which reacts to heat and expands to seal the opening in the event of a fire. It has been successfully fire tested at Exova Warringtonfire Ltd to FD30 rating when fitted in the door core and to FD60 rating when fitted in the timber top rail. The test was carried out to the methodology given in BS476 part 22 (1987).

From the outside, it looks exactly the same as a standard SupaStyle letterbox and has all the smart design features which customers already love, such as a patented concealed flap operating mechanism, an anti-leak weather channel in the frame, and full 180° internal and external opening. There are two size options in the fire rated version, with telescopic sleeves allowing it to be adjusted from 20/40mm or 40/80mm to fit into any thickness of fire door. Both these sizes are available in three finishes – polished stainless, polished PVD gold stainless and brushed stainless. These suite perfectly with the rest of Mila’s Supa stainless steel door furniture ranges, and come complete with the same reassuring 25 and 10 year no quibble guarantees on finishes and mechanical performance.

With some manufacturers of fire doors reporting sales up by as much as 25% in 2016, Mila says it is responding to real demand in the market from customers who want a proven and durable stainless steel letterbox solution which they can fit and forget.
