Zipscreen blinds can be a great addition to alfresco areas, but it’s essential to ensure proper ventilation for safety. When using plumbed-in gas barbecues, Australian Standards (AS/NZS 5601.1) require sufficient airflow to prevent the buildup of harmful gases like carbon monoxide.
The standards do not explicitly address blinds or other removable coverings, so definitive advice on their impact is not provided. However, to maintain ventilation, Zipscreen Blinds should be installed or raised to ensure at least 25% of the total wall space in the outdoor area remains open.
For additional safety, we recommend installing a carbon monoxide detector. Furthermore, whenever operating a gas appliance, such as a barbecue, outdoor blinds should always be raised to ensure adequate ventilation.
Please note, while these recommendations reflect best practices, only a licensed gas fitter can provide definitive advice on compliance with building and safety regulations for your alfresco area.
