Access points into the metal duct component must be sealed with fire rated access panels tested to AS 1530 - Part 4 and /or BS 476 Part 24, and shall not have combustible seals. Access panels shall have been tested to AS 1682.1-1990 Section 5.3 for air leakage.

LAF’s Igniseal solution offers access and inspection panels designed and tested in combination with our composite or stand-alone systems. These negate the need for a primary access panel the majority of which have combustible rubber gaskets (ie a fire risk) to maintain air tightness and a further supplementary access panel to maintain the fire isolation function.

There is a need to protect elastomeric bearing pads from fire as they slow char by fire and can have serious consequences to the structures supported by these elastomeric pads.

LAF has developed a highly cost effective and demountable solution to protect elastomeric bearings in civil or building construction structures against fire. The Vermibloc system solution is fully tested  to comply with ISO 834 and AS 1530-4. 

The Vermibloc system is made up of the following proprietary material elements:

1. Vermitex TH bedding mortar;

2. Vitrave metal extrusion;

3. Expegni expanding seal;

The Vermibloc fire protection system for bearing pads used in civil or building construction uses a prefabricated rectangular fire resistant block placed around the elastomeric pad. This fire protective enclosure does not come into contact with any building components but is capable of bridging the 15mm air gap and providing fire protection for up to 2 hours, through the use of our Expegni intumescent technology.

The construction industry is fast recognising that carbon fibre reinforced polymers (CFRP) are an ideal solution for many problems found in new as well as refurbishment projects.

The drawback is that common epoxy adhesives used to bond the CFRP to the concrete are very sensitive to temperature variations. The epoxy loses most of its force-transfer ability when the temperature reaches between 70°C-81°C. Passive fire protection to enhance fire endurance becomes inevitable to enable engineers and builders to use these innovative systems to strengthened structural members. 

Through Vermitex® LAF has developed a passive fire protection solution that will maintain the temperature of the CFRP below 90°C so that its tensile strength is retained in the event of a fire.
