ES-SO is a non-profit making umbrella organisation, and is an association of the solar shading industry's national professional associations from the EU member states. This also makes ES-SO a very objective association. All the national associations are ES-SO full members and have voting rights.
However, not every EU country's solar shading industry has a professional association. In these cases, or whenever there is a national association which has not chosen to join ES-SO, we recruit prominent companies from the solar shading industry which share ES-SO's ideals and objectives. These companies become associate members and have the same full member rights until a national association becomes a member.
ES-SO also welcomes supporting members, namely companies from the solar shading industry which support ES-SO's activities and objectives but which may already be represented by their professional association.
ES-SO welcomes applications for membership from companies or organisations which meet the above criteria. See
