The premium product from elka-Holzwerke

esb Plus

The wood-based panel with the Blue Angel ecolabel and tested low emissions

esb Plus – for certified, constructive timber construction and prefabricated house construction

For all timber builders, elka offers the premium board esb Plus – the qualitative answer for healthy building and living. It is the first wood-based board on the German market to meet the high requirements of the stricter Blue Angel guidelines (version 1.1.2017) and the first and only wood-based board to be recommended in the low-emission Sentinel Haus Portal since 2016. The board was awarded the international innovative prize of the Iconic Award 2017 Winner and the Material Award 2018 in the Ecology category.

Esb Plus meets the high requirements of the MVVTB (Musterverwaltungsvorschrift Technische Bestimmungen) for wood-based materials.

Another new feature is the possibility of processing as a sarking board N+F for the roof area in accordance with the ZVDH regulations/Cologne. It thus offers a wide range of applications in structural timber construction.
