Insulated Dry-lining Plasterboard for Mechanical Fixing

Kingspan Kooltherm K18 Insulated Plasterboard is a super high performance, fibre-free rigid thermoset phenolic insulation, sandwiched between a front facing of tapered edge gypsum based plasterboard, and a reverse facing of low emissivity foil autohesively bonded to the insulation core during manufacture.

  • Made in Australia
  • 3-in-1 insulation, dry-lining and vapour control
  • Clear cavity is maintained - resists moisture penetration
  • Group 1 NCC fire classification
  • Practical for modular construction 
NCC 2019 compliant brochures and AU made

Assumption and Key

NCC 2019 prescribes different methods to determine Total R-value Calculations for Volume 1 and Volume 2. The systems noted on this page are Total R-values for the building element as required by the Energy Provisions of the National Construction Code, calculated in accordance with AS/NZS 4859.2 2018 & NZS 4214. Kingspan Kooltherm® products are manufactured, tested and packaged in conformance with AS/NZS 4859.1:2018


Fire Resistance

Examples shown are suitable for NCC Class 1 & 10a housing and Fire-Resisting Construction Type C walls in NCC Class 2 – 9 buildings. For Fire-Resisting Construction Type A & B walls in NCC Class 2 – 9 buildings a Performance Solution is required. Please contact Kingspan Insulation Technical Services on 1300 247 235 or email technical@kingspaninsulation.com.au for further guidance.
