LIMBER WITH TIMBER
Helping achieve height with strength in mid-rise, wood-frame buildings is a relatively new wood product called cross-laminated timber.
It’s a form of engineered wood that stacks kilndried timber boards at right angles, with surfaces glued together.
The boards are then pressed to make solid structural wood panels.
They create a stronger product that can be used for parts of mid-rise construction, such as creating elevator shafts instead of using concrete, or for larger structural components in taller buildings.
Cross-laminated timber has been used in Europe to build nine-storey buildings and is being considered for a highrise in Finland.
Environmental selling points are that crosslaminated timber is a renewable resource, production minimizes waste, and panels can be produced in a range of standard and customizable sizes.
It also has the potential to be carbon neutral, says the crosslaminatedtimber.com.au website.
