Browse Forums Kitchen Corner 1 Sep 08, 2009 10:13 pm Hey guys, We are getting our new splashback installed on Thursday and our glazier has advised we need to cut out a section of the new plaster and replace it with fire resistant plasterboard behind the gas cooktop about 200-300mm high off the benchtop. Has anyone done this before? I'm a bit concerned as I believe it is generally 13mm thick and the standard plaster is 10mm thick, won't that mean it will cause the splashback not to sit flush? Thank, Bailey. Energy efficient custom built house - Moving In 3 Weeks Re: Fire resistant plaster behind splashback 3Sep 09, 2009 10:42 am We had a glass splashback put in in our old house in mid-2007 behind a gas cooktop in Melbourne, but no mention was made of a requirement for fire-resistant plasterboard. Maybe there are different rules where you are ? Edit: Nope, just realised you are in Melbourne also !

Re: Fire resistant plaster behind splashback 4Sep 09, 2009 10:53 am It is a requirement that if the burner is less than a certain distance away from the splashback(I think it's 200mm), then you need to install fire resistant board behind the splashback, otherwise it doesn't comply (and most cooktops probably wouldn't comply with this measurement). You don't need a 13mm plasterboard, you can buy a millboard, which from memory is 9mm.

Re: Fire resistant plaster behind splashback 8Dec 27, 2010 2:28 pm We had a glass splashback put in our new kitchen and actually have a burn mark on the glass where it touched the flame... our clearance was very small (80mm) and are now having trouble getting people to accept liability for the mistake. I believe it was because of this building requirement not being met! Re: Fire resistant plaster behind splashback 9Dec 27, 2010 6:44 pm ^ As the law says, if a bad thing theoretically could happen, it will happen (especially if you have a window close by (which I do and prefer to keep it open or ajar while cooking ) ). Some people from this thread http://forum.homeone.com.au/viewtopic.php?f=16&t=42055 might also be insterested to hear of this. My signature is distracting people from my wise posts ...

Thank, Bailey. Fire resistant board is required by law in all cases behind a glass splashback except for brickwork. Some plaster board supplies and Reece plumbing in Melbourne can get you that although it is quite expensive and the board comes in three thickness 6 and 9 mm I do not recall the third measurement. Re: Fire resistant plaster behind splashback 11Dec 29, 2010 7:55 pm Intersting topic. Thanks for bringing that up.

Glad you said that. I'm wasn't going to have fire resistant board behind our splashback as we have double brick and I thought it was silly of a stardard to say that we needed fire resistant board and have brick behind it. Re: Fire resistant plaster behind splashback 13Jan 11, 2011 11:18 pm Hi, I got told this same thing by a glass installer once. Until I recently the truth about it all when we were getting ours done. When you get a glass splash back in your kitchen, all the glass is normal glass except the piece behind your hot plate. The glass companies harden the glass to withstand the heat. The companies that tell you to put fibro behind the glass is because they are getting out of it the cheap way by not having to harden the glass. Don't want to sound like a know-it-all but I had it straight from the horses mouth of a glazier. Simon Re: Fire resistant plaster behind splashback 14Jan 12, 2011 8:02 am But it is still a referencable Australian Standard that one needs to have a fire resistant backing behind a glass splashback. Toughened or not, glass is still an excellent conductor of heat. And as far as I know all of a glass splashback should be made of toughened glass, not just the section behind the cooktop - it's not just heat resistance that is important, impact resistance is also very important in any kitchen work area.

The glass companies harden the glass to withstand the heat. The companies that tell you to put fibro behind the glass is because they are getting out of it the cheap way by not having to harden the glass. Did I understand this correctly, or are you saying that they can manufacture just one area of the same piece of glass to be hardened, or are you saying that this would be a separate piece of glass? In other words, what happens for long splashbacks where the cooktop is somehwere in the middle (in front of that long piece of glass) ?? My signature is distracting people from my wise posts ...

Re: Fire resistant plaster behind splashback 18Jan 12, 2011 3:43 pm Strumer But it is still a referencable Australian Standard that one needs to have a fire resistant backing behind a glass splashback. Earl That is correct. Your kitchen will not comply with the Australian Standards unless you have a fire resistant backing behind your splashback. It does not matter what your splashback is, you must have the fire resistant backing. Re: Fire resistant plaster behind splashback 19Jan 22, 2011 2:07 pm simon88 The companies that tell you to put fibro behind the glass is because they are getting out of it the cheap way by not having to harden the glass. Simon Simon, I work with splashbacks and I ll have to say what you were told is untrue. The fireproof backing board will not prevent the glass from cracking. If the glass behind the cook top hasn't been toughened - it will crack sooner or later. The fireproof backing is there to prevent whatever you have behind the wall not to catch on fire, because without it , it gets pretty hot. simon88 When you get a glass splash back in your kitchen, all the glass is normal glass except the piece behind your hot plate. Simon That is a generalisation. It depends on who does the job. Also having powerpoint cut outs and holes in creates a weak point, which could make the glass if you put some force on it. Toughened glass will never crack. Old Home Restoration / Renovation Hi, just discovered all these junks left behind under the floor. Could any of these be asbestos?
