Whether your premises are residential or commercial, timber always transforms a building into something more. Timber has been the companion of humankind since the beginning - maybe this is why we feel so comfortable with timber around us. This website provides architects, designers and customers with ideas for the many applications of beautiful, efficient, timber conservatories, orangeries, sunrooms and windows and doors.


Christian and Sandra Rampe

Christian and Sandra moved to New Zealand from Germany in 2005. One day Sandra needed to clean their windows and was astounded to discover she had to go outside! In that moment the idea for Thermadura was born. Christian has many years of study and experience working in European Joinery and Cabinet making in Germany. After finishing his joinery apprenticeship he studied industrial timber engineering at the FFB in Detmold.  Sandra has a masters degree in economics from the University Essen. Together they make the perfect team.
















Our Mission

Our mission is to manufacture conservatories of exceptional quality. Accredited laboratories have tested all our components from the glue over the surface coatings to the hinges.  Exterior joinery constantly has to face harsh elements and to be able to stand the test of time; only the best materials are good enough for our conservatories. As well as using only top quality materials, our workmanship is essential in crafting a quality product. At ThermaDura we stick to a tried and true recipe; our internal quality assurance process ensures that only quality products leave our factory.


Our goal is to grow our business in a sustainable way by always supplying quality. We know that our business depends on your satisfaction.


At ThermaDura we understand the necessity of having a knowledgeable and helpful point of contact for you. Our knowledge is based on years of hands on experience in the German and New Zealand window and conservatory industry. We can help by providing realistic and efficient solutions for your project.  We invite you into the world of ThermaDura and hope you enjoy our website.





Our experience in CAD CAM technology enables ThermaDura to manufacture exceptional conservatories and European windows and doors efficiently from design to finish. Our conservatories are designed with state-of-the-art 3D software which is integrated into the CAD CAM system which is connected to the CNC machines.


We also produce a range of beautiful blinds. Sandra looks after production of our TwinGo honeycomb and Cosiflor pleated blinds. These blinds offer the perfect sun protection for all joinery products. We manufacture the blinds in our factory in Mosgiel with materials sourced from Germany. The honeycomb blinds are on display in many interior design shops around New Zealand.
