Harmonica system

Minimal light loss.

Concertina insect screen systems have been specially developed for continuous vents, but are also suitable for other types of vent. ALWECO works closely with roof suppliers on new greenhouse construction projects. This cooperation is essential in order to ensure that the system takes up as little space as possible in its fully retracted state. The system’s compactness means that the insect screen gauze is virtually invisible and results in virtually no light loss.

The system cannot always be fully installed on all types of existing vent, but light loss remains negligible. The way in which the system has been assembled means that it is less vulnerable to wear and tear, and is more durable than traditional systems.
