Installation

Please follow the following instructions carefully:

Installation:
  • Always store the boards in a dry place. Only install the boards if they are dry.Suggested board thickness for use with GUTEX Thermofibre® blow-in insulation: ≥ 60 mm
  • Install boards perpendicular to framed construction, making sure they fit tightly.
  • Avoid cross joints.
  • Do not use damaged boards.
  • Seams and interruptions, such as dormer walls, chimneys, etc., must be tight against wind and driving rain.
  • Cut to size with common woodworking machines.
  • Boards are not designed and made to provide structural support, strength or bear loads.
  • Avoid exposure to high levels of moisture on the interior sides of the boards.
  • Vacuum off the dust in accordance with applicable workplace safety regulations or practices.

Intallation - Walls

  • Following on-centre distances apply:

    20 – 40 mm board thickness → max. on-centre is 62.5 cm

    60 – 100 mm board thickness → max. on-centre is 83.5 cm

    120 – 160 mm board thickness → max. on-centre is 93.5 cm
  • Stagger/offset the joints from row to row by min. of 30 cm.

Installation - Roofs

  • Maximum on-centre distances for rafters is 90 cm
  • Stagger butted side joints with the next row’s joint being centred no closer than the next rafter.
  • void walking on areas between the rafters.
  • Fasten the board immediately after placing in position and cover it for protection with roofing paper, sheathing or sarking (e.g. GUTEX Multiplex-top). Fasten counter batten through the protective covering and into the rafters. For your convenience in determining the most suitable fastener, you'll find fixation forms under "Service"
  • GUTEX Ultratherm is not a load-bearing structural element (e.g. snow).
        Fastening in vented facade applications
        • To determine the wind load for your specific zone (pursuant to DIN 1055-4:2005-03), use the wind zone map.
        • You'll find information about the quantity of nails and their spacing in the GUTEX Multitherm data sheet.
