Passive roof ventilation nz.
Ventilation prevents damage to ceilings and roof timbers helps control mildew.
Vent s vented batten is the only batten in nz designed with calculated airflow specifically for roof ventilation.
With effective roof space ventilation less heat is radiated into rooms allowing air conditioners and fans to be more efficient.
Whilst it is possible to retrofit passive ventilation solutions to existing buildings it is highly recommended to incorporate passive ventilation during the design phase of any new building project.
Roof ventilation achieving calculated continuous and unimpeded airflow through the roof cavity is relatively straight forward.
It allows calculated airflow of 18 000m per linear metre.
Tion questions around the needfor passive ventilation elements to give new zealand roof cavities a breath of fresh air have been investi gated by branz researchers since at least 1988.
