Au.diVent data sheet Product Description

Durable fibre cement sheet panel with modular slot style perforations. Suitable for use as a ventilation panel or as an acoustic panel when supplied with our optional Integrated Acoustic Backing (IAB) or when installed with an appropriate absorbent backing material. Au.diVent is available with a choice of panel joint details to suit specific requirements and is ideally suited to high humidity or corrosive applications. Au.diVent helps to reduce ceiling space heat build-up and condensation by allowing natural ventilation of the roof space through the Au.diVent eaves.

Product Features– Unaffected by steam, moisture, sunlight or vermin– Excellent water resistant properties– Ideal for harsh environments– Variety of jointing options– Suitable for curved surfaces

Variations– Slotting module can be customised to suit special

width sheets (consult Atkar Technical Staff )– Square or recessed edge

Jointing Options– Vee or Expressed Joint– Recessed edge for Flush Jointing– PVC H-Mould– Cover Mould

Installation Details The table to the left provides a fixing guide for general commercial applications.

Au.diVent sheets should be fixed at right angles to framing where possible with sheet ends coinciding with framing members. Do not fix sheets directly to the underside of roof framing or structural members. Battens or furring channels must be used. Closer framing centres are required for high wind applications and where sheets are to be curved. For these applications or where flush jointing is to be incorporated, contact Atkar Technical Staff for details.

Jointing Details Please note. Acoustic insulation and selected scrim are only applicable in acoustic applications.

Au.diVent data sheet Product Description

Au.diVent slotted eaves lining allows eaves to be simultaneously lined and vented, admitting fresh air to the roof space and enabling detrimental moist air to flow out through its continuous slotting pattern. With the durability inherent to fibre cement sheet, Au.diVent provides cost-effective long-term benefits.

Refer to Au.diVent, Slotted Fibre Cement, Data Sheet 2.1.1 – 2.1.3 for fully slotted panel details.

Product Features– Summer – reduces building heat load during the

day by removing hot roof space air, which in addition prevents condensation forming at night

– Winter – helps prevent the accumulation of warm moist air in the roof space, from heaters, cookers etc allowing insulation to work most efficiently and also helping to prevent condensation

– Enhances the appearance of eaves– Will not burn or rot and is immune to

permanent water damage– No operating costs or moving parts
