Our electrically operated Expel retro fitting fly screen, with its very small roll, is ideally suited to being internally retro-fitted in the small space above windows and patio doors on domestic properties, or over larger openings in restaurants or food preparation areas.
The curtain is made from glassfibre and PVC to ensure that insects are kept out whilst airflow and visibility is at a maximum.
For options that incorporate a shutter into this design, please see our Expel Ultra 41mm and Expel Ultra 55mm.
