Woodspan PLT Panels
Description

Woodspan PLT Panels (parallel laminated timber) are glue laminated, structural panels used in buildings for use as floor and roof structures including diaphragm applications.

Similar to CLT, Woodspan PLT Panels are manufactured by Taranakipine from New Zealand grown Radiata Pine.

Woodspan PLT panels are made from finger-jointed or whole timber boards that are then laminated into large panels. Boards are glued so that the grain runs parallel (in the same direction) to the primary span, creating a strong, structurally efficient panel.  

Panels are available in a visual grade, suitable for use in applications where the structure is left exposed to the interior, and a non-visual grade, where the structure will be covered with flooring overlay or ceiling linings.

The maximum panel size is 7200mm x 890mm and available in 90mm, 117mm, and 140mm thicknesses. Panels are available untreated or treated to hazard class H3.1 or H3.2. All panels are supplied with a factory applied temporary waterproof coating.

Key Features
  • Fast — Prefabrication of Woodspan PLT panels offsite using advanced CNC technology ensures fast and accurate installation, reducing labour costs and keeps material waste and construction noise onsite to a minimum
  • Structurally efficient —  As all grain goes in the direction of the primary span a strong, structurally efficient panel is produced. Building with mass timber products like PLT can result in a significantly lighter superstructure than concrete or steel. This can reduce foundation sizes and cost, especially in areas where difficult ground conditions exist, or in high seismic zones
  • Timber aesthetics — Available in a visual grade to take advantage of the natural beauty and warmth that wood products bring to a building
  • Wood from renewable sources is the only truly sustainable construction material available. Wood acts as a carbon store — a vital tool in helping to combat climate change. Woodspan PLT panels are manufactured from 100% New Zealand Radiata pine logs from sustainably managed plantation forests.

Scope of Use

PLT panels are suitable for use as floor and roof structures including diaphragm applications:

  • In any wind zone or calculated wind pressure (ULS)
  • In all exposure zones, excluding microclimates as defined in NZS 3604:2011
  • In conjunction with a primary structure that complies with the NZ Building Code or where the designer has established that the existing structure is suitable for the intended building work
  • In all hazard classes up to and including H3.2
  • As a diaphragm where specifically designed
  • In applications where NZ Building Code Clause C6 (structural stability) obligations apply
  • Woodspan PLT Panels may be used with floor loadings up to 3.0kPa
Limitations on Use
  • Specific design required for fixing capacity where the wind zone is greater than extra high or the ULS is greater than 2.5 kPa
  • Fastening materials to be in accordance with NZS 3604:2011
  • Where uses a diaphragm the design of connections to bracing elements is subject to specific design
  • In applications where NZ Building Code Clause C6 (structural stability) obligations apply, the use of Woodspan PLT Panels is subject to specific design by a fire engineer
  • Floor loadings up to 3.0kPa — specified fixings to meet floor loadings and floor panel thickness
