ES-SO welcomes new members! ES-SO is an umbrella organization, whose members are the national trade associations of the solar shading and roller shutter industry in the EU member countries. However, recognizing that some countries may not have a trade organization, ES-SO accepts other categories of members, at the discretion of the General Assembly:

Full members: national trade associations of the solar shading and roller shutter industry.

Associate members: in those countries that have no trade associations, ES-SO accepts companies with a leading market position in the solar shading and roller shutter industry. This also holds true for countries whose trade associations are not ready yet to become ES-SO member.

Supporting members: companies from the solar shading and roller shutter industry of good repute which cannot apply for associate membership, or organizations of related industries which are interested in supporting ES-SO activities.

To apply for membership, please send a message to This email address is being protected from spambots. You need JavaScript enabled to view it. or write us a letter with some basic information on your association or company.
Acceptance of membership is a decision of the General Assembly that will be communicated to the applicant within a reasonable time.

Thank you for your interest !
