Quotation and General Information

How can I request a quotation?

If you work at a sunshade company, you can submit a quote request to us through the contact form on our website. When submitting a request, please make sure to include a clear photo or drawing (showing the height and width) of the specific window(s) in your request.

Does Guillaume Janssen sell its products only in the Netherlands, or are your products also available abroad?

We sell our products worldwide. We collaborate with a few reliable partners abroad who install and maintain our screens on location.

Does Guillaume Jansen also provide the installation and maintenance of sunshade systems?

No, we never do the installation or maintenance of sunshade systems ourselves. We can, however, assist with the installation if needed. It's also possible for us to provide an explanation of the installation of our systems; this can be done in our own factory/training space upon request.

Ordering and Delivery

Can I, as a private person, also order products directly from you?

Guillaume Jansen is specialized in the manufacturing of unique sunshades. Unfortunately, we do not sell our products directly to a private person. However, it is possible to order our products through one of our partners.


What types of fabrics can I order from Guillaume Janssen?

We typically use Mermet, Serge Ferrari, Sauleda, and Ten Cate as our fabric suppliers. Upon request, we can also engage other manufacturers such as Copaco or Helioscreen.


Can Guillaume Jansen accompany us during on-site measurements?

If you have confirmed an order, you can always approach us for assistance during the measurement process. It is best to contact us by phone so that we can schedule a joint appointment with you.

Can we use all types of fabric for the systems that Guillaume Janssen sells?

This depends on the type of system you want to order. For very large ZIP systems, we can only use Soltis 86 or Soltis 92. For screens from our MW Series (systems for unique shapes), we use only Soltis 92 fabric or Soltis B92 (opaque fabric).

What is the lifespan of your sunshade systems?

If our systems are regularly maintained and cleaned, they can last for 10 to 15 years.

Maintenance and Use

Do your sunshade systems require maintenance?

Our systems require annual maintenance, especially those with cord/tension spring mechanisms. These systems need additional maintenance after installation to ensure proper tensioning. For specific maintenance instructions, we recommend referring to our maintenance guidelines.

Warranty and Terms and Conditions

What warranty do you provide for your sunshade systems?

Unless otherwise stated, our systems have a 2-year warranty. Please note that most systems require maintenance. More information about the warranty can be found in our terms and conditions, which can be downloaded from this website.
