General Details

AAH125HP – Rytons High Rise Super Acoustic Controllable LookRyt AirCore

  • Retro-fitted core ventilator for background room ventilation. Fitted from the inside.
  • Allows the introduction of fresh outside air into the room to disperse moisture, odours and other airborne pollutants.
  • Use in noisy areas to reduce the amount of noise entering the building for a more peaceful environment.
  • Ideal for high rise constructions and may also suit rendered finishes as no external fixing required.
  • Unique draught-reducing panel manually adjusted with an easy push/pull or tilt action allowing air to be controlled as required.
  • Paint or wallpaper the panel to match room décor for a discreet appearance.
  • External water baffle prevents transfer of water across the cavity.
  • External grille U.V. stabilised to slow down the effects of sunlight.
  • Patent No. GB 2523676.

Questions & Answers:

  • Will installing more than one vent to achieve a greater free area have an effect on the acoustic performance? We asked the BRE who said “The performance of the ventilator will not degrade when you put in more of them. The composite sound insulation performance of the façade will degrade if you increase the number of ventilators, assuming that they are one of the weaker links.”
  • Will the vent reduce sound from inside to outside as well as from outside to inside? The BRE has advised us that it’s reasonable to assume that ‘reciprocity’ applies to the vents. That is, the third octave values for sound reduction index are the same in both directions (out to in and in to out).
