The Sonoslot® is a self-regulating, sound absorbing slotvent kit consisting of an external slotvent, internal slotvent and a plastic sleeve with integrated sound-absorbing baffle in-between.

The Sonoslot® is available in 4 sizes:

  • 275 mm
  • 375 mm
  • 475 mm
  • 700 mm

The aluminium external slotvent is self regulating. This keeps the airflow fairly uniform in strong winds and prevents draughts. The external slot vent is perforated and also acts as an insect screen.

The noise-damping baffle is standard 70 mm thick and the plastic sleeveis standard 90 mm thick, but both can easily be adapted to suit different window frame depths.

The small, narrow and discreet aluminium internal slotvent can be closed completely. When open, it deflects the airflow upwards to prevent direct draughts.

The Sonoslot® comes as standard with a satin anodised finish (E6/EV1-SAA) (20 micron) or powder-coated in RAL 9010, RAL 9005 and RAL 1247 (60-70 micron). The colour-fast, weather- and UV-resistant endcaps are in white (RAL 9010) or black (SAA, RAL 9005, RAL 1247).

The Sonoslot® is suitable for all window depths, can be used on all types of window frames: timber, uPVC or aluminium, and is ideal for renovations or new builds.
