Browse Forums General Discussion 1 Dec 12, 2008 12:44 pm My "Ideal" floorplan means I am forced to have the long wall of a WC right againced a bedroom wall, worst still is that it will be very close to where the bedroom headboard will be
I have upgraded the door on both the bedroom and WC to solid core but I have the room in the wc to make the 90mm internal brick wall double thickness (2 x 90mm) as long as I dont include a 50mm airgap. As I am only interested in acoustic insulation and not thermal, do you think that thickening of that wall will make toilet users inaudable to the bedroom occupants Thank you in advance for your replys and a big thank you for having me onboard homeone. Re: WC on other side of bedroom wall - soundproofing ideas ? 2Dec 12, 2008 12:50 pm I think it would definately be worth it, we have our ensuite toilet backing onto bed 2 and it really is audible, not everything but the flushing is loud, Well done for thinking of it, I wish I had, Oh well, next time! Re: WC on other side of bedroom wall - soundproofing ideas ? 4Dec 12, 2008 6:37 pm What about if you put some sound buffing insulation in the walls, that should help. Internal and External Building and Colour Consultant Online - Worldwide http://www.denovoconcepts.com Re: WC on other side of bedroom wall - soundproofing ideas ? 5Dec 12, 2008 8:55 pm haha... just made me think our our last house. bubba girls cot was on the other side of the wall to our ensuite toilet. She would be quiet in the mornings till I got up to flush the loo. Then she would KNOW we were awake! no more sleepins.
anyhoo, back to the subject, I would definately be adding another brick wall if I could, or maybe CSR's sound screen. Built a modified "Daydream 279" .. Cor@l Homes on a flat 4473m block!! And lov'n it!!! Re: WC on other side of bedroom wall - soundproofing ideas ? 6Dec 12, 2008 10:15 pm seakyl I would definately be adding another brick wall if I could, or maybe CSR's sound screen. Michelle What about if you put some sound buffing insulation in the walls, that should help. None of these will be as cost effective as Acoustiflex. It is what the industry refers to as a mass loaded vinyl (MLV). It a very dense, thin, flexible material that 'catches' the sound. The sheet weights 10kg/m2. The manufacturer has a developed a green friendly version which uses recycled materials. It won the ABC New Inventors award. I wish I knew about it before the gyprock went up. Re: WC on other side of bedroom wall - soundproofing ideas ? 7Dec 13, 2008 1:26 am Are you building in WA, having internal brick walls sounds like you are?
You could always ring the brick company and ask. Have you checked out the 'Acoustic Maxibrick' or 'ecobrick'? From the ecobrick website... "Excellent Acoustic Barrier ecobrick possess an excellent sound reduction capacity and will meet Building Code requirements. This property results from the unique aerated structure which consists of tiny non-interconnected air cells giving a very low air porosity. Hence the sound resistance achieved is better than anticipated for a material with low mass"... I have noticed a couple of building companies use this brick internally rather than the clay ones. Maybe find out what would be better acoustically (and cost-wise too) a double internal brick wall or maxibrick. I really have no idea myself and loathe double brick, but as there is no other option here, there is nothing I can do. Re: WC on other side of bedroom wall - soundproofing ideas ? 8Dec 13, 2008 9:39 am To compare products you are looking for the STC (Sound transmission class) of the product. An STC of 45 or higher will block out loud speech. Most acoustic products will quote this:

Tel. 1800 326 326 Re: WC on other side of bedroom wall - soundproofing ideas ? 11Dec 15, 2008 10:12 pm Yak_Chat Whats the cost per m2 for Acoustiflex? Not sure but here is a quote from the New Inventors website: "The upshot is that if you put $5 of their QuietWave material in, say, an ordinary $80 hollowcore door, you can give it the same acoustic properties as a $1000 acoustic door. Put it in a solid core door and it becomes a $1500 acoustic door." http://www.abc.net.au/tv/newinventors/txt/s2423228.htm You could email them. Re: WC on other side of bedroom wall - soundproofing ideas ? 13Dec 17, 2008 2:11 pm I've got this issue as well, but there's nothing I can do about it now, in my 12 year old apartment.
Our ensuite is really small and very close to our bed, as the toilet is on the wall right near where the bed is. I never use the ensuite once my partner's in the bedroom cause you can hear absolutely everything. Not just flushing. EVERYTHING, including if someone is breathing in there. Seriously. When I'm on the phone in the bedroom, I have to close the ensuite door or my voice echoes weirdly in the bedroom, just from the major acoustics in the ensuite! I'd be surprised if any sort of insulation could silence a flushing toilet. Our other bathroom is down the hallway from the bedroom, and we can easily hear it when the toilet flushes. We can hear when the person upstairs flushes (and other things ) and we can hear when the people next door flush too...I always assumed that was fairly normal. How the hell did I become a senior member!? I know nothing! Re: WC on other side of bedroom wall - soundproofing ideas ? 14Dec 17, 2008 3:14 pm grace_slick I'd be surprised if any sort of insulation could silence a flushing toilet The whole issue of acoutic insulation is a challenging one. Sounds have a pesky way of finding their way around things. In your case it could possibly be down the pipework and conduits. They can also travel through air gaps, studs and joins. You may have to address several mechanisms simultaneously to achieve the desired effect. Re: WC on other side of bedroom wall - soundproofing ideas ? 15Dec 24, 2008 6:36 pm sorry for the delay replying
Kiribilly - Its comforting to know its mainly the flush thats audable, its actually the 5th WC which should only have reasonable hours use as it will be mainly used for visitors as all other people have there own WC in there ensuete. The house will be used myself and 3 FIFO workers as tennants (@ $280 pw each) . When the guys are on there 1 week break they like to party hard, drink heaps. Might have to develop a "if its yellow let it mellow" house rule. Mostly there will only be a maximum of 2 tennants home at once but if one is starting there break and the other is trying to sleep the day before they start there 12 hour shift after drinking solid for 6 days, I fear a problem may develop. Hence the pre emtive strike. Dynonite 69 - Sounds like U know your *hit. At this point I may leave acoustiflex for the walls as a "If all else fails" option. Nonetheless, after ecoclassics comment I think I wil put an extra noggin or 2 in between the rafters above the WC and put some on before the gyprock goes up. Michelle - I think that options out as I havent got the room for 2 walls of maxibrick and a 50mm gap for insulation. Thank you for your suggestion anyway Seakyl - No kids 2 worry about waking for me, my x looks after them Monkyupatree - Yep building in double brick externals 90 florentene limestone, 50 airgap and 90 maxibrick. Have upgraded all maxibrick to accoustic as the price per pallet difference is negligable. Thanks for the link though as it looks like emitting the airgap on an internal double wall might bugger things up based in the difference between using wall ties or not as shown on the link. That was the main question I wanted to ask the masses. Ecoclassic - Your point is very informative and somthing I have overlooked until your post. I will have R3 fibreglass insulation in the roof which should help, especially if I put acustiflex above the gyprock in the WC. I will look into the feasability of changing to sonarbats in leau of the R3 fibreglass. To comply with BCA I only require R2.5 total and I think I will be going sarking under the colourbond which gives me 1.5 from memory so if the sonar bats give me at least 1, I am in. It also brings up the point that I may not get the full benifit of your double glasing from outside noise blocking as I have no insulation in the eaves. Thanks heaps for all of your inputs.
