Weepa has a range of products to help you comply with the relevant Bushfire Attack Level (BAL) referenced in NCC:2019 Australian Building Code and published as AS3959:2018. Protecting weep holes is critical to prevent sparks and embers entering the wall cavity and causing unseen ignition of combustable materials in the cavity and the roof.
