Bricks for new house in Sydney 9May 11, 2018 9:17 pm Hebel requires acrylic render, so add up $60-$75 per sq m + GST to your calcs. When not rendered properly, cracks are probable.
Bricklayers are expensive in Sydney, some of them charge up to $3 per brick those days, but generally expect to pay $1.7-$2 + GST for your bricklaying. Acoustically, brick will perform a bit better as it is more solid in comparison to AAC (AAC has air cavities inside and is narrower - 75 mm vs 110 mm). Main sound bottleneck will be still your windows, so consider double or tripple glazing if you want to see improvements there. Most of the windows, even double glazed, provide less than 40 Rw of acoustic filtering. So in most cases, both Hebel and brick will perform pretty much at the same level. Hebel performs a bit better thermally though, but just a bit and the difference can be easily compensated with your insulation choice. Double brick with proper insulation in between will perform MUCH better than Hebel. Properly insulated thermal mass provides low variations between the temperature after your lag, e.g. yes, it gets a bit hotter in the evening, but only like 3-4 degrees difference to morning temperature during 40+ degree days. So you just ran your AC for couple of hours before going to bed or even just ventilate by opening up your windows at night. Only few people insulate double brick properly those days (with rigid panels of high value between the bricks) as in most cases insulation requires increasing a cavity size, i.e. wall thickness. Insulated double brick is obviously the best of two worlds, but comes at a premium (stronger footings, wall chasing for services, gyprock to brick, etc.). Consider poly ICF or Durisol ICF as alternative and cheaper option (require same footings as brick veneer and costs are pretty much comparable). All those are structural and load bearing, so you save on frames. You can learn more about Durisol material here: https://www.facebook.com/DurisolAustralia/. It is used a lot in Canada and States and provides superior thermal and vapour permeability performance + thermal mass. ICF walls are also up to 7 times stronger than double brick walls. The second best option to consider is reverse brick veneer. It also comes at a premium and you would need to do chasing for services and use weatherboard or rendered rigid insulation for externals. Hope it helps. Re: Hebel Vs. Bricks for new house in Sydney 10May 11, 2018 9:46 pm homey1 hello everyone, can anyone please share an objective opinion on this? I'm also torn between hebel and bricks. bluebaowie, di you end up deciding what to choose? my builder is. pitching hebel to me at no extra cost, with all the upside its hard to resist. i just want to make sure i mke due diligence before going to hebel.

Render has no Structural capacity whatsoever, nor is it considered in any of the structural code calculations. It can crack when Hebel joints under the render expand or contract as there is no mortar used to connect Hebel panels together. Re: Hebel Vs. Bricks for new house in Sydney 13Jul 07, 2020 7:54 am CustomHome42 Hi, Like you, we concidered every option, pros and cons for both hebel and brick. Whilst both are similar, if your after the modern look, hebel has it all over bricks. As render is an applied product, it’s important to concider what it’s being applied to. Bricks require bricklayers, and when bricklayers lay commons suitable for render, the mindset is it will be covered, therefore the laying lacks skill and the bricks are slapped into place knowing render will cover them. Hebel, is installed by professionals, knowing the importance of straight and plumb walls, suitable for render. After months of deciding, we used the steel frame, hebel walls, and render, and honesty it looks great. We used the Stoddarts system. Here’s a video so you can see how good it goes together. (Not our house being built, our builder is slow, however using Stoddarts we achieved the quality and the look we where after). https://vimeo.com/126077254 Cheers hi, hope your built has been good, for hebel build people say the skill of installation helps avoid cracks later on, would you mind sharing details of your hebel installer please, we are considering hebel...in sydney I was looking at different options for a fence for my build and Hebel PowerFence seemed like a good option (one of the criteria was a solid wall look). However, I don't… 0 5906 1 6638 1000000% definitely add insulation. I have in my home and it makes a big difference minimising sound transfer. Insulation is pretty cheap and definitely worth it 2 6211 |
