In contrast to the Mono folding wall the Progress has double-walled panels.

The light construction and light materials give the Progress optimum ease of use. By using wear-resistant acoustic rubbers the Progress does not need a bottom rail. The drag rubbers provide perfect sound insulation (28-31 dB Rw).). Of course many finishes are also possible here. The Progress is only available in a single or double wing version.
