Shaftliner
Description

Shaftliner panels are specially manufactured fire-stop plasterboard panels, developed for use in USG Boral's Partiwall system.

They are also suitable for use in the Plasterboard Cavity Shaft Wall system to provide fire protection for elevator shafts where installation is possible from one side only.

Key Features

Physical properties:

  • Edge profile: bevelled edge
  • Thickness: 25mm
  • Width: 600mm
  • Lengths: 3000mm and 3600mm
  • Weight: 20.5 kg/m² (nominal)
  • Early Fire Reaction properties — Group 1-S
Scope of Use

Applications: Fire rated systems, suitable for vertical ducts, elevators shaft and intertenancy wall systems

  • Shaftliner is suitable for use in all commercial and residential situations provide that its specification and installation is in accordance with the USG Boral Partiwall Installation Manual — NZ and the USG Boral System + Manual.
  • It is suitable for installation on timber framed walls, where the building design falls within the design scope of NZS3604, or AS/NZS1170.
  • Where Shaftliner is to be installed in an existing building, the installer must assure themselves that the framing and existing building are suitable for the proposed building work.
Limitations on Use
  • The specification of Shaftliner must be in accordance with USG Boral information.
  • It must be specified by an LBP, able to provide a design memorandum to the relevant Building Consent Authority (BCA), if RBW provisions apply.
  • Installation must be undertaken by or supervised by an LBP (carpentry licence). If RBW provisions apply, this same LBP must complete the RBW memorandum.
  • Shaftliner Board should not be exposed to sustained temperatures exceeding 42ºC or to excessive, repetitive or continuous moisture before, during or after installation. All sources of moisture should be eliminated immediately.

  • C6.2 (a): CSIRO assessments
  • G6.3.1: CSIRO Measurement No TL429em (2004), CSIRO Measurement No TL429qrs (2004), CSIRO Measurement No TL469 (2006)
Other Performance Attributes
  • Fire: Shaftliner is a non-combustible building product and achieves a material group 1-S depending on finished coating applied (BRANZ Assessment FH4435). It achieves fire resistance ratings depending on the fire rated systems application.
  • Acoustic: Shaftliner may be used in an acoustic system to provide required levels of sound insulation to achieve specified acoustic ratings.
  • Sustainability: Shaftliner has been manufactured using 100% recycled liner paper. Independently tested for VOC.
