Application

For increasing room ventilation in habitable rooms.

Description

An opening with airflow controlled automatically by a mineral wool slab, avoiding undue draughts, with an effective area well above the minimum requirement for habitable rooms. Kitchens and bathrooms will generally require mechanical ventilation to cope with the greater amounts of moisture generated. Air tested by the Building Research Establishment for airflow rates versus applied pressure difference.


Features and benefits:

  • No moving parts.
  • Works passively 24 hours a day.
  • Quiet operation (makes no noise).
  • Low installation costs.
  • Designed to fit 230 x 155 mm aperture (i.e. standard 9 x 6" airbrick).
  • Reduces draughty airflow and heat loss.
  • No running costs.
  • Works at peak condensation times.
  • No night time disturbance from compressors or fans.
