TIMBER
CLT typically takes timber that did not quite make the SG8 grade (45 mm thick), removes defects (splits, large wane, large and loose knots, etc), finger joints it together and then planes it (typically down to 42 mm), ready for gluing and pressing into panels.
The benefits of Red Stag’s CLT are:
• Domestically supplied and available
within the same time frame as frames and trusses.
• Treated to New Zealand NZS3640 treatment standards: H1.2 Boron; H3.2 CCA. • Panel sizes up to 16.9 m long x 4.9 m wide x 0.42 m thick and anywhere in between. • Locally CNC machining available to precision cut, drill, rebate all requirements to the mm in factory.
• Significantly improved installation times and reduced labour. • Reduced carbon footprint, site waste and site noise. • Solid stair systems (see Figure 4), installed inside 30 minutes, supplied with the midfloor and capable of carrying construction loads and free of creaks.

The most common panel thickness is 126 mm (3 x 42 mm), which achieves a 60/60/60 fire rating, and can achieve up to 4.6 m spans2, making it suitable for the majority of floors, walls, roofs, stairwells and lift shafts.

This is the first of a series of educational CLT articles. In upcoming issues of Building Business, we will discuss topics such: • The simplicity of lifting and installation • Fixings • Design • Exceptional fire performance • Acoustic management. Prior to starting a project where CLT is a solution, please contact your local ITM and have them coordinate with Red Stag Wood Solutions to support (www.redstag.co.nz). For enquiries, send an email to: ewp@redstag.co.nz
