Cut costs, but not safety, with the ITS.11204

Would you like to save money and time without cutting corners? If you are fitting 54mm fire doors purely to accommodate concealed closers, we can show you how to make savings!

Why thicker doors are used even where a 44mm door is all that’s necessary

A 30-minute fire rating is the common safety standard prevailing in commercial and communal buildings, and plenty of 44mm doors can deliver this. However, where concealed door closers have been specified, thicker doors than necessary often end up being installed instead. This is because concealed closers can normally only be fitted within doors at least 54mm thick, due to the intumescent layer that  prevents heat transfer being applied around every side of the closer. This adds to the closer’s overall depth, making it too bulky to sit within a 44mm door.

However, it is perfectly possible to install fully compliant, 44mm thick 30-minute fire doors with a concealed door closer, thanks to Rutland’s ITS.11204.

Through careful development, Rutland achieved comprehensive 30-minute protection with intumescent applied solely along the top side of the ITS.11204 concealed door closer. This has a 32mm profile, enabling it to fit easily within a 44mm fire door, as demonstrated in this video. Thorough fire testing has comprehensively proven that the ITS.11204 is fully compliant and performs reliably to the 30-minute fire rating.
