The Protecta FR Board consists of a high-density rock wool board which is coated with fire retardant paint on one or two sides, depending on where the fire sealing is to be carried out.
The rock wool is to keep the temperature increase down, whereas the fire retardant paint is designed to prevent fire and hot gases from leaking through the mineral wool board. Currently, this is the most common fire sealing method as it is a quick way of sealing big and/or complicated fire seals when the fitter has some experience with the system. Measurements have shown that you often only spend half the time compared to the traditional mortar system and that it may even be used in wet areas as well as outdoors.
The fire board has been tested on all types of through-penetrations in all types of constructions and may also be combined with Protecta Cable Transit, Collar and Pipe Wrap. It is also ideal for closing over all types of ceilings against concrete floors and has been approved for upgrading of all types of floors.
