While the massive wood on the internal side provides a natural, aesthetic and healthy appearance for the winter garden, the aluminum on the external side ensures heat, sound, wind and rain isolation. The aluminum section does not require any maintenance. The strength of the composite winter garden profiles made of snap- on profiles prevents the sagging that may occur in time. Since it is supported with steel construction, the usable life of the internal skeleton is equal to that of the building. The wooden part can be detailed with modern lacquer and classic wood colors.
