NZ Building Code compliant AS1530.4-2014 & AS4072.1-2005. Acoustic Rating STC 55. Smoke seal tested.
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.
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 sealing gaps above firewalls to floor or ceiling/roof structure above and has been approved for upgrading of all types of floors.
Protecta FR Board can be installed inside the aperture or outside the wall overlapping the aperture (pattress fitting). Even single-sided 50mm FR Board can be pattress fitted provided the uncoated side is bonded to the wall using Protecta FR Coating.
Tested under BWR 3 for smoke - rated for smoke protection up to 200Pa.
Protecta FR Board can be over-painted with most emulsion or alkyd (gloss) paints.
Rated Y1 - for use at temperatures below 0oC, with high humidity or with exposure to UV, but not rain.
