Browse Forums Building A New House 1 Mar 22, 2015 4:00 pm Does anybody know if to comply with BAL 12.5 in Victoria that windows that can be opened need to have metal type mesh screens fitted? What about doors, do they require screens too? Do builders need to supply and fit screens prior to handover and to comply with all regs? I know I am paying an extra $4500 for BAL 12.5 but don't have all the specifications that compliance means as far as construction goes. Re: BAL 12.5 and windows and doors. 2Mar 22, 2015 4:20 pm Im building in nsw so unsure if its the same. My BAL is also 12.5 and yeah we need aluminium mesh to all openings. We are paying $5000 for the BAL upgrades and the mesh is included in that price. My builder will have them fitted for handover.
