The Trimesh® - Vermitex® separating membrane element is the thinnest and lightest solution for high vertical membrane element where structural members are absent. LAF systems have been approved for vertical spans of up to 7 m. For higher walls lightweight steel members may be used to break-down the wall height into smaller wall sections. To date the largest single vertical drop successfully designed and completed by LAF in collaboration with our Applicator, using the Trimesh® / Vermitex® TH system, is 15 m and was completed on the Venetian Entertainment Venue in Macau.
In many instances, the system has been approved for use in providing separation for fire lift shafts where the available space to install such fire barriers is often scarce.
The Trimesh® wall can easily circumvent any slenderness ratio restriction given the way the system was tested and the design features incorporated into the system during the construction of the vertical elements. Putting it simply the Trimesh®-Vermitex® system is uniquely positioned to ensure that limits of the slenderness ratio do apply. The wall is suspended from the structure above and can never be ‘toppled over’ like a brick wall can.
In all tests for the Trimesh®-Vermitex® two way wall system we present a case where the wall is a non-load bearing element and therefore load considerations are not required, however the LAF two way system can be re-engineered by changing the internal steel rods or providing additional external supports to cater for loads up to 5,000 Pa.
LAF can supply and erect if required any off-site manufactured pre-fabricated type of Fire Compartment Wall or Fire Shaft System that can fulfil any requirements and deliver an economical, simple and aesthetically appropriate solution for any project. The LAF offer is for a specified fire protection of the passages tested and certified on past projects to Australian Standards and regulatory requirements.
