I-Board and I-Board Plus

„The pre-fabricated cladding for front wall installations.“

Product information

The fully prepared solution for cladding WC dry wall installations. Both solutions include all components required for quick and easy cladding of WC dry wall installations. The choice of the right cladding element depends on the final surface design, e.g. small or large-format tiles, mosaic or plaster.

wedi I-Board (1200 x 1245 x 20 mm) is a pre-fabricated element for the cladding of wall-mounted WCs. With a width of 1,200 mm, it can easily be adapted to virtually all needs. The connection to the carrier element is made either with wedi 610 adhesive and sealant or alternatively with the wedi Tools washers and the included self-tapping screws. Despite the the I-Board being light weight, it is extremely strong, stable and is suitable for large-format tiling (up to 400 kg weight load from a tile size of 10 x 10 cm). The installed cladding board can be tiled directly without further surface preparation.

Especially for plaster and mosaic tiling - the wedi I-Board Plus combines all the benefits of the tried and tested wedi I-Board but has an additional reinforcement plate integrated in the factory. As a result, the pressure load from the attached WC ceramics is perfectly offset so that the dry wall installation can be individually tiled with mosaic from 2 × 2 cm or plastered (plaster ≥ 3 mm).

  • Simple and quick to install
  • For tiles, plaster and mosaic 
  • Can be cut individually
