Ember screens and BAL ratings explained

Much of the Blue Mountains is bushfire-prone land. If you are building, renovating or simply want more protection, screens are part of the picture.

What a BAL rating is

A Bushfire Attack Level estimates how much ember attack and heat a home could face. It is worked out for each property.

Why screens matter

Embers can drift through open windows and vents. Metal mesh with small openings helps stop them.

Metal, not fibreglass

Fibreglass mesh can melt. Ember screens use steel, bronze or aluminium mesh.

Who decides

Your builder, certifier or council confirms what your BAL rating requires. We supply screens to suit.

Everyday benefit

Metal mesh keeps insects out too, so you get year-round use. See window fly screens.
