VERSATILE - CAN BE USED IN ANY FRAMING SYSTEM

Klasse's external sheathing is designed to be installed on:

  • Light steel infill and oversail systems on concrete and steel frame buildings

  • Modular buildings

  • Light gauge steel frame

  • Timber frame buildings​

OTHER TEST RESULTS & INTERESTING POINTS TO CONSIDER
  • Acoustic Performance: Acoustically tested according to ISO 10140-2.

  • Thermal Performance: Additional insulation can be installed without detrimental effect on the fire or acoustic performance.

  • G-board has an extremely stable substrate and will only enlarge by fractions of a millimetre when humidity increases. This means the boards can be installed flush. The board is constructed to be vapour open allowing moisture trapped with a wall to escape.

  • As the core is gypsum it locks moisture into the crystal structure which reduces temperatures in the event of a fire.

  • G-board construction will not add fuel when used in a façade capacity. It will reduce the transmission of a fire if other materials combust in the façade.
