This Exaco Riga Greenhouse Automatic Window Opener allows the opener to be disconnected in adverse weather conditions. These attach to the Riga roof windows and open them automatically based on temperature. The paraffin oil in the chamber expands starting around 72° F to push the windows open when temperatures rise, and doses them when temperatures fall.
