Product Overview

To maintain market leadership, Trafalgar stay up to date with the latest

technologies and trends in passive fire protection and contemporary

construction techniques. We are 70 years strong and still innovating!

Maxilite is a lightweight, high performance fire rated board. It is a calcium silicate based

product, bonded together with non-organic binders, that meets all requirements for

asbestos, volatile organic compounds (VOC’s) and ozone depleting potential (ODP)

Compounds. Maxilite boards are available in a number of discrete thicknesses for use in

the fire protection of structural steel. Maxilite has been tested to various local and

international test standards and is suitable for a large range of steel sizes and types.

How does it work?

Maxilite is an extremely effective insulating refractory board. The Maxilite board is stable

under high temperature stress and remains strong and crack free, even when exposed to

fully developed fires. The Maxilite board provides a thermal insulation as well as a heat

sinking capacity for steel.

Key Features • Lightweight

• Low thermal conductivity

• Up to 4 hours fire-rated protection

• Fully Tested and Approved for the Australian market

• Various methods of installation

• No mess

Fire Damper Upgrade Systems

Often Brick or block work is finished short or left missing to allow for the installation of a fire damper. Maxilite Fire Damper Upgrade (MFDU) systems allow for the installation of a fire damper whilst simultaneously sealing the oversized penetration and maintaining the fire integrity of the wall as required by the Building Code of Australia.
