Internal Blind Technical Specifications

The ScreenLine© pleated blind SL20C and the ScreenLine© ventian blind SL20C designed for use in double-glazed units, are manufactured in accordance with high technical specifications and production stndards. The slat raising, lowering and tilting function is achieved using a rotational magnetic transmission through the glass thereby guaranteeing the unit's hermetic seal. The external magnet, fixed to the internal glass by double-sided high performance adhesive allows perfect alignment with the internal magnet. The raising and lowering operation is achieved using a continuous cord loop that drives the internal magnet.
