Browse Forums Windows & Doors 1 Aug 24, 2010 4:19 pm We are unlucky enough to be building in an extreme bushfire rating area (-40 BAL) in the middle of Sydney. But that's another story.
I have a couple of questions if anyone can answer with some experience in this area. Trend windows advertise their bush fire rated windows as such, but just wondering if they are the only ones we are able to use? Just had the quote back from them and almost fell off the chair as our house design has a lot of glass. Also some window manufacturers request a window schedule whereas our building designer says any manufacturer worth their salt should be able to work from plans. Do I need the added expense of a window schedule for quotes assuming I can use someone other than Trend? Re: -40 BAL WINDOWS 2Aug 24, 2010 4:27 pm Trend are your only current option for rated windows. You can however use roller shutters. If the look of these distresses you, they can be recessed into your eaves so they can't be seen when not being used. No window manufacturer needs a window shedule however it takes out any room for error. You dont need one. just tell them the windows are "as per the plan".

Trend didn't need a window schedule to quote so that saves some $$$. It's pretty disturbing though that there isn't any competition in this market. So everyone in a bush fire zone uses either Trend windows or shutters? Unfortunately shutters won't work in the design of our house - the windows extend all the way to the pitched roof. Re: -40 BAL WINDOWS 4Aug 24, 2010 10:04 pm Oops - made a big blue but in a good way. We're not -40BAL, it should have been -29BAL (level 3). Do I now have any alternatives for glass manufacturers?https://forum.homeone.com.au/posting.php?mode=reply&f=23&t=37606# Re: -40 BAL WINDOWS 5Aug 25, 2010 8:58 am BAL 29 is the limit of most. You can talk to Dowell, A&L Windows, Bradnams and others.

So that covers fire compliance as well as excellent thermal performance. Let me know if you would like any more details/reports etc. Cheers, Brad ------- Re: -29 BAL Windows 8Aug 27, 2010 12:09 pm Hi We are a bal 40 in victoria it states that the windows need to be 5mm toughened glass with screens bronze or steel 2mm thick , we were getting roller shutters with ordinary windows but they are not rated yet so they now have to come and replace the glass in the windows SOots viewtopic.php?f=31&t=31037 harvard 27 DFH signed contract 16th March 2010 slab down 1st June 2010 frame started 8th June 2010 trusses and frame finished 24th June 2010 tiles almost done 14th July 2010 Bricks started 14th July 2010 Plaster started 28th July 2010 Paint 25th August 2010 Re: -29 BAL Windows 9Aug 27, 2010 3:26 pm sootymay12 Hi We are a bal 40 in victoria it states that the windows need to be 5mm toughened glass with screens bronze or steel 2mm thick , we were getting roller shutters with ordinary windows but they are not rated yet so they now have to come and replace the glass in the windows SOots Make sure the screens supplied cover both fixed & opening sashes.

Re: -29 BAL Windows 10Aug 27, 2010 3:33 pm Just to add for general information - the BAL is directional from the fire source so if there is a side of the dwelling that is 'sheltered', then the requirements do not apply to that area.

Re: -29 BAL Windows 11Sep 06, 2010 9:29 am We have the 5mm toughened gIass and also the screens as well- But I have just been up to my house this morning and I am NOT happy about the screens they have installed on my doors (the widows aren't up yet). They are basically normal flyscreens but made of flimsy metal/mesh. I thought they would have to be quite solid- I was thinking more like the crimsafe metal. I need to find out what they are supposed to be like so I can make sure I am not being ripped off. Lisa- Finally in our house!!!

Hi LJ I am pretty sure the screens and doors need to be 2mm thick steel or bronze screens not the ordinary fly screen on all windows and doors Tammy viewtopic.php?f=31&t=31037 harvard 27 DFH signed contract 16th March 2010 slab down 1st June 2010 frame started 8th June 2010 trusses and frame finished 24th June 2010 tiles almost done 14th July 2010 Bricks started 14th July 2010 Plaster started 28th July 2010 Paint 25th August 2010 Re: -29 BAL Windows 13Sep 06, 2010 2:08 pm Hi LJ - sounds concerning. I'm finding these BAL regulations a minefield and we're just in the quoting stage. Judging by the quotes we're receiving back from manufacturers there seems to be a lot of confusion. We've had quotes ranging from $20K to $100K. We have a lot of glass so the $20K quote was just wrong, all 3mm glass - I don't think they even looked at the fire regulation documents I sent along with the plans. Re: -29 BAL Windows 14Sep 06, 2010 3:02 pm j&r Hi LJ - sounds concerning. I'm finding these BAL regulations a minefield and we're just in the quoting stage. . I'm hearing you! And trying to get information today has just been a nightmare, everyone condradicts each other in their information. One says to me ******* aluminium mesh is fire safe- how that is possible I do not know, then someone else tells me no-it should be 2mm steel mesh like what Sooty May said. It's just nuts. Even ringing the actual building commision- the person there did not have a clue! Lisa- Finally in our house!!! Re: -29 BAL Windows 15Sep 09, 2010 1:45 pm To date I have found that all the major window manufacturers are very well aware of the BAL requirements (in Vic) & that basically if you supply a floor plan, site plan & BAL report they will quote / supply the correct configuration after consultation. The screens referred to are - 'a mesh with a maximum aperature of 2mm, made of corrosion - resistant steel or bronze.'

That could have happened during the build, or may be happening currently. There are water stains above a couple of windows… 2 3830 |
