Certificates & Test marks
InstallationAccessoriesPlease 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.
