Timber Framed Mid-rise Design Guide

An introductory guide to the use of LVL in multi-residential and commercial buildings

The Wesbeam LVL in Timber Framed Multi-Residential Buildings  document available for download below provides the latest technical information to assist in the design and construction of mid-rise timber-framed buildings (typically up to eight-storeys in height) using laminated veneer lumber (LVL) and e-joist products which meet fire and acoustic requirements. 

Specifically it covers the following:

  • Deemed-to-Satisfy Fire-protected Tmber provisions of the National Construction Code 2019 (NCC)
  • Lightweight timber-framed systems that achieve a fire resistance level (FRL) of 90-minutes and 120-minutes
  • Acoustic design considerations
  • Required evidence of suitability to demonstrate compliance with the NCC

This document also describes the timber-framed system performance and informs the reader of the commonly available fire-grade plasterboard products and systems along with additional links to technical design guides and product catalogues that may assist in the design and construction of mid-rise timber buildings.
