PLT stands for parallel laminated timber and CLT stands for cross laminated timber. Their use and application is similar with the key difference being that in PLT, all laminates run in the same direction of the grain with the timber working on its edge. Each panel is effectively 21 joists working as a single unit. CLT laminates however are laid-up on their flat face with every second laminate layer running across the grain. While CLT panels are larger in dimension than PLT panels, PLT panels have a longer span for the same panel thickness.

We undertook an independent assessment on an apartment block comparing a PLT panel mid-floor installation, to a traditional timber floor joist/plywood system. The PLT floor was completed in two days compared to two weeks for the floor joist system.

Shop drawings are a set of construction drawings that show piece by piece, how the PLT is to fit together within the building or project. Woodspan will take the architectural and structural drawings and create a PLT layout showing each component we are manufacturing. These drawings will then be issued back to our client to verify if the shop drawings correctly represent the design specified in the construction documents. Sign-off often involves review by the architect, engineer and contractor. Once approval is given, the shop drawings are uploaded to our CNC machine and components can be manufactured.

Yes they can!

We suggest they are coated with polyurethane (or similar) to provide further protection and enhance the look.

Radiata pine is a softwood so wearing from foot traffic is to be expected.

An important consideration when using an offsite manufactured product is the shop drawing process.

For a small project this may be as fast as 1 to 2 weeks. For larger, more complex projects, reviewing and signing off on shop drawings may take a month or more. Once shop drawings are signed off, then allow 8 – 10 weeks for manufacturing and delivery.

Fire resistance ratings on Woodspan PLT floor panels have been established through independent, full-scale load-bearing testing to test method AS 1530.4:2014. For fire span tables and details download our Design & Install Guide.

Woodspan panels with a 21mm spline joint can achieve a 30/30/30 fire rating. A 60/60/60 rating is achieved with the factory installation of a Ryanfire strap in the panel to panel joint.
