Technical advice
In order to be able to give the advice and attention that are appropriate for each project, our technical services team stands ready to field all of your questions.


As a manufacturer, it is our duty to provide technical support to all of our partners. A project manager is assigned to each region to answer your questions. In addition as a professional you have access to a number of technical services.

Quite often, standard solutions do not satisfy the creative wishes of the client or the specific requirements of the project. Thus Cantillana operates a consultancy office where technical advisors take entire projects and work them into customised, detailed plans. These include everything from analyses of critical points, surveys and detailed drawings to follow-up on the work site.

Technical Documentation

Detailed technical drawings and ready-to-use specification sheets are available for all Granol’therm systems. In the Downloads section, you can find all necessary certificates, technical sheets, surveys and implementation guidelines.

Telephone and Technical Advice

During the execution of your project, you can count on us for technical and telephone support. You can rely on not only your Cantillana contact person, but also on our technical advisors who will gladly help you with your specific questions related to the work at hand. Ask your Cantillana contact person and he or she will bring you in contact with the technical advisors.

Handling of Complaints

We wish that no one had complaints - since we do our very best every single day to offer a high-quality range of products – but sometimes they are unavoidable. As a manufacturer and your supplier, we will not let you down! We are there for you even after the completion of your project. A specialised technical staff person is available for you when you have complaints on the work site. When issues arise, please do not hesitate to contact us at
