Saunaboard Flex

the hottest board in the sauna sector

Half-round and round parts are gaining more and more ground in modern sauna construction. Likewise due to the small thickness this board can be used for visible tongues. There are no limits to its design possibilities.

  • Quick Facts
    Pallet size: 72 units
    Purchase quantity: Can be produced from 1 unit up
    Thickness: 4.0 mm with 0.6mm veneer top layer
    with 0.8 or 1.5mm veneer top layer correspondingly higher (other thicknesses on request)
  • Quality
    Front side A = visible quality
    Back side blind = blind veneer without quality standard
  • Joining Method
    Sliced veneer top layers joined in solid character
  • Gluing
    D4 the latest generation acc. DIN EN 314 Part 2 Class 3. The gluing quality with regard to water resistance and temperature stability has been tested for sauna suitability under laboratory conditions over a significantly long period.
  • Scope of Application
    Radius parts (curves) as well as visible tongues (tongue- and groove panels) in high-quality sauna-, infrared-, heat cabin- or wellness centre construction (interior design of the cabins). Can also be used for BIO- or steamer saunas with appropriate afterdrying and ventilation of the facility (max. short-term humidity 60 – 70%). Not suitable for wet rooms and steam chambers (100% humidity).
  • Inner Layer
    Plywood structure (peeled veneer) made from European aspen or alder (no exotic wood!). FSC® as well as PEFC™ certified veneers can be provided on request. The colour of the inner layer is matched to the top layer (aspen or alder).
  • Top Layer
    Sliced veneer top layers standard approx. 0.6mm (hardwood), 0.8mm (softwood). Other veneer thicknesses on request. The Saunaboard from J. Grabner sets new standards in design. Very many types of wood as well as embossed optics (Saunaboard Structure) are available in the standard range.
  • Processing
    For fixing the Saunaboards we recommend a combination of gluing and screwing the board elements. Due to the great variety of sauna constructions, with a different method of fixing we advise the person performing the work to check this beforehand and to continue working accordingly. For softwoods, thick veneering as well as old woods we recommend brushing the boards before installation, in order to prevent these woods from splintering and flaking off later.


  1. many design options (large and small panels)
  2. large selection of wood types and surface structures
  3. no emitting pollutants in the gluing according to test certificate ÖNORM 6219-1
  4. large formats (optimisation; less waste than small formats)
  5. inner layer made from compact aspen or alder wood (sauna wood); as a result high screw retention for optimal fixing
  6. inner layer colour matched to top veneer layer (light wood → light inner layer = Aspen; dark wood → dark inner layer = Alder)
  7. no exotic wood – conserving resources (carrier board)
  8. FSC® or PEFC™ certified on request
  9. pallet size: 36 units
