Agra Wool International Group from The Netherlands, is worldwide known for their substrates and water absorbing natural rock wool products for growers. After extensive testing with the product’s density, Agra Wool in 2018 has developed a product that has the same characteristics as floral foam in terms of use; Sideau®In contrast to floral foam, that is made from oil derivatives and phenol resin – which is plastic – Sideau® is fully biodegradable. Therefore Sideau® is perfectly suited for florists and flower arrangers who want to use an fully environmental friendly base for their creations.

About Sideau®

How it is made

Sideau® is made of Earthwool®, a natural product made from basalt, a volcanic igneous rock. In addition, Sideau® is made with Ecose®, a natural binder, free from acetylates and formaldehyde’s. In the composition of the binder, therefore, petrochemical raw materials make way for vegetable raw materials like sugar beet or cane sugar. By heating, the material caramelizes hence the brown color. During the production of Earthwool® , seventy percent less energy is required than in the production of traditional yellow rockwool. Sideau® is noticeably softer but still very dense, does not emit any odor or discoloration in the water. Sideau® is therefore friendly to people and the environment. It does not crumble and is therefore pleasant to process.

Our Story


The product name Sideau® is derived from the first name of the owner of Agra Wool, which is Sido. Furthermore the name consists of two phrases: Si and d’Eau, which explains one of the main characteristics of the product: it absorbs and holds water perfectly. Even better than the traditional floral foam. So, yes, water!

Sideau® is going to change the world of environmentally conscious florists and flower arrangers and for sure is the 100% biodegradable floral foam alternative.
