Universal Slate Ventilator

Installation advice for the Universal Slate Ventilator

  • When fixed at 1m centres and a minimum of 1m up from the eaves, a ventilation property equivalent to a 10mm continuous air gap is achieved
  • Use the product as supplied for the larger slate option (610mm x 305mm)
  • Cut the product along the guide lines for smaller slate options
  • The ventilator replaces one normal slate
  • The two roof slates directly beneath the ventilator must be cut to accommodate the felt penetration sleeve at the rear of the slate vent (cut away the minimum possible to achieve a tight fit using the slate ventilator as a template)
  • Cut an X into the felt 200mm x 105mm at the point of the felt penetration sleeve, fold up/outwards the four triangular flaps to form an aperture 200mm x 105mm which will accommodate the sleeve, nail the top flaps over the battens
  • Position the vent and nail it into the batten through the nail slots provided
  • Secure the front of the vent using a copper disc rivet
  • Connect the pipe adaptor kit to the underside of the slate vent if required
  • nbs plus
  • riba
