The Series 4 fire rated doors are 46mm thick and were introduced following requests from architects and specifiers for a one hour fire resisting door less than the 54mm thickness normally available. A Timber perimeter framed high density flaxboard core offers a strong and sturdy door very popular for use wherever doors of better than average strength and durability are required.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Dequette is consulted before specifying.
