German Conservatory System - Manufactured in New Zealand

"Wintergarten" is the German word for conservatory.  ThermaDura "Wintergarten" conservatories have the best insulation as we intend to create a 'living space". To ensure that you can use your conservatory all year round we use high performance Low-E double glazing (U-value of 1.1) as a standard. We also supply blinds to protect you from the sun, and we can advice -in cooperation with your architect or draughtsman- on the best heating/cooling and ventilation system for your location and design.

We use a “post and beam” design with naturally durable timber (WR Cedar, Siberian Larch) which is also thermally efficient.

The ThermaDura "Wintergarten" conservatory system is a modular conservatory system that allows you to have the best quality conservatory. We currently offer either a gable or a pitched roof conservatory in different sizes and variations. See our "Wintergarten" conservatory range here.
