“How much extra is it for a BAL-FZ rating on the Wollongong?
Sean, Newcastle NSW
BAL-FZ typically doubles the price of a project as light material can not be used for external cladding. Instead, brick-like materials or hebel panelling needs to be used.
The flame zone will add a layer of complexity to your project as the building code requires a wrap-around protection system for BAL-FZ zones.
