Browse Forums Building A New House Re: Unique Solar Chimney in new SIP construction house 24Apr 06, 2014 2:20 pm The 120mm panels work at at about $70/m2. Install materials, allow another $10/m2 NOTE: 120mm = R3.4......to compare apples with apples, stick framing would have to be at least 180mm thick (double stud walls) to accommodate R3.6 Batts.....there is thermal bridging loss in sticks (unless those studs are staggered) therefore dropping effective R-values. SIPS = more bang for your buck!!!! Re: Unique Solar Chimney in new SIP construction house 25Apr 06, 2014 3:31 pm The only reason I suggested rendering is that is what has been done to the MgO panels I've seen - admittedly only two houses or should I say one house then a part of another. As far as I know Dulux Acratex is not a paint you have to apply it with a trowel so in my book that pretty much makes it acrylic render = rendering. Good luck with it though, I look forward to more pictures of your build. Stewie Re: Unique Solar Chimney in new SIP construction house 26Apr 06, 2014 4:17 pm Hi Stewie....totally agree ...Acratex is a render system & the one we specify for Superior Panels.....however, painting is still an option but the use of battens are strongly advised over external joints. Re: Unique Solar Chimney in new SIP construction house 27Apr 06, 2014 6:49 pm bearing in mind the nature of the mgo board as a substrate, can you use the acretex AcraShield without the trowel on render undernaeth- seems unneccasry? or something like rockcote armour- another flexible membrane that straddles the paint/render divide? Re: Unique Solar Chimney in new SIP construction house 29Aug 24, 2014 12:24 pm Yes, I can provide an update. The interior is nearing completion & we moved in about 2 months ago. We're both in awe about how comfortable this house is & how well it sits in with the environment. Admittedly, it has been cold internally, but there are many unfinished gaps so the house leaks like a sieve, but is quick to warm up. http://i36.photobucket.com/albums/e26/stevesakiwi/e9c84269-4d4a-40b8-b06f-a1a82bbd0126_zps2dbc890e.jpg I have built pelmets into most of the rooms. These have an energy efficiency advantage in preventing thermal loss between curtains & cold window glass. Concealed LED lighting will provide mood lighting to the ceiling. http://i36.photobucket.com/albums/e26/stevesakiwi/hh1ensuite_zpsf80f5fb7.jpg This is the ensuite to main bedroom...vanity & WC is in foreground. The rain-head shower is a luxury we look forward to at the end of the day....so is the bath that overlooks the bushy gully. http://i36.photobucket.com/albums/e26/stevesakiwi/ff0b1224-227b-482b-ad48-805b6bd62100_zps69c40945.jpg This is the entrance 'carpet runner' using European style tiles Please feel free to ask more questions & I'll post more photos soon....Steve Re: Unique Solar Chimney in new SIP construction house 30Aug 26, 2014 11:44 am In further comment to 'leaks like a sieve'...NO WAY is this a reflection on the performance of SIPS. There are a number of unfinished areas that allow draughts....eg: I have just completed door stops & draughts strips to the 1200 entrance pivot door.....got gaps in stair well, some windows & garage door to finish.... Another thing to consider is the expanse of single glazed windows in living (>70% wall area) & bedroom. Insulation rating of SIPS walls are R3.2 (equiv to 190x45 studs with R3.6 batts!).....whereas single glazed windows are approx R0.12.....huge difference & represent a huge hole in the thermal envelope.....needless to say, house still rates 8.5 Stars. I anticipate that thermal curtains with pelmet will lift windows to approx R0.5.....a huge improvement. Re: Unique Solar Chimney in new SIP construction house 31Aug 29, 2014 8:14 pm Hi efficient design, great thread and the house looks awesome. I'm interested in owner building our house sometime in the next few years and have been researching SIP's. I want to do whatever parts of the actual building process I can manage myself with help from my father, brothers and wife. SIP's are of interest to me because the promotional material claims a small team of people with minimal experience could manage to put one up. My father is an architect, carpenter and has worked as a builder though he doesn't have a licence in Australia. Myself and brothers have a very little experience with building, having helped build our family log cabin years ago. I was wondering what your thoughts are on whether or not to believe the promotional material. Do you think it feasible that a party of 4-5 people without SIP's experience but some general building experience, could build using SIP's? The plan is for a very simple, single level home in the country, nothing as fancy as yours. I mean just the shell really, not all the electrical, plumbing etc. Re: Unique Solar Chimney in new SIP construction house 32Aug 30, 2014 2:45 pm SIPS are simple.....I feel that even an inexperienced person, who can follow a simple 'lego' plan, could assemble a SIPS structure.....simply, panels just slot together with glued/screwed splines.....then screwed to bottom/top plates. With my project, myself (i'm 58) and another chap had the upstairs walls up in a week. That included reworking the panels for the gables. We spent the next week preping for the roof and joinery. The roof was installed in 1 day by a contractor. SIPS are fast & simple & you end up with a more energy efficient house. Many thanks for your comments.....Steve Re: Unique Solar Chimney in new SIP construction house 33Aug 30, 2014 5:52 pm Steve the house looks amazing! Great job! You must be so pleased. How long did it end up taking from floor to move in? It seems super fast. Do you want to advise the company you consulted with / got your SIPS from? EDIT - just saw in another post above Re: Unique Solar Chimney in new SIP construction house 34Aug 30, 2014 7:57 pm Thanks for the reply Steve. Good to know the promotional material from all the new SIP's companies isn't just pie in the sky stuff. I'm becoming more and more convinced that SIP's will be the material of choice. I like the energy efficiency and the cost savings from being able to do a fair bit of the construction ourselves. Re: Unique Solar Chimney in new SIP construction house 35Aug 31, 2014 3:45 pm Thanks PKFFW.....I firmly believe that in 20 years time, SIPS will be the predominate building system....you just need to look at the exponential growth in the northern hemisphere, and with increasing demand for energy efficiency due to rising energy costs, the future for SIPS is secured. Would be interested in what systems you have looked into?.....Steve Re: Unique Solar Chimney in new SIP construction house 36Sep 02, 2014 9:59 am I've only just started looking really. Haven't really looked hugely deeply into any specific suppliers as yet. Just their blurbs and advertising materials on websites. I've come across sipsindustries, ozonepanel, superiorpanels, Magroc amongst others. It's interesting reading about the different materials and systems. However, I've been way more interested in trying to find real world experience of people who have built with SIP's and whether or not it is a workable choice for owner building. That's why I was glad to find your thread and get your response. Re: Unique Solar Chimney in new SIP construction house 37Sep 02, 2014 12:22 pm Quote: Hi Stewie D, this is not quite true. MgO SIP suppliers do recommend the use of an acrylic render system, but it is also possible to seal & paint the MgO external surface. In this case, the use of battens over the joints is used. I'm aware of 2 houses within 50km of me that have been finished in this way, but that's not the look we want. You need something to hide or cover the joins. Rendering and painting is one way and looks a lot more professional. Battens look like a DIY has had a go at it. I've seen houses with Hardies F/C sheet clad like this then finished with battens and it looks like a '60's house. Stewie Re: Unique Solar Chimney in new SIP construction house 38Sep 02, 2014 3:19 pm Yep....now that the interior is nearly finished, we'll commence rendering the exterior with an acrylic render system. http://i36.photobucket.com/albums/e26/stevesakiwi/751e4c66-6b55-4e7e-b989-434ed0025d85_zps18a1e116.jpg Photo of galley style kitchen. Bifold window opens onto the dining deck. Bird life here is amazing....started counting the # of species & currently at 44 varieties of birds.....most viewed from kitchen sink! http://i36.photobucket.com/albums/e26/stevesakiwi/7dcdc729-e3bb-45c5-bf0e-2a2706304bec_zps6be76948.jpg Kitchen bench looking into dining. The appliances (induction hob, d/washer & oven) were all sourced as part of the 'Choice' purchasing service. The appliances rated very high in Choice magazines & a Choice representative negotiated the best deals for us....saved many $100's. Re: Unique Solar Chimney in new SIP construction house 39Sep 09, 2014 9:07 pm Thanks for the thread E.D. A few questions if I may: [1] How many people are required onsite to put panels together? [2] Is a crane required to move the panels into position? Can a panel be carried by one person? [3] Do the panels require water proofing? [4] Do the panels need to be lined internally or externally? [5] How is plumbing and electricity passed through panels? [6] Is $80m2 retail price? [7] How can a buyer be sure they are buying only compliant product? Thank you. *btw did you use Superior Panel roofing? I hear these types of roofing are very loud when it rains. Re: Unique Solar Chimney in new SIP construction house 40Sep 14, 2014 8:35 am Hi James,.....apologies for taking so long on getting back. Here are answers to your questions:- 1) 2 people can assemble a SIPS house.....that's all I had on my project. 2) A crane is not needed & it takes 2 people to handle a panel....not because of weight, but because of shear size & bulk. 3) Panels require exterior/interior finishing....prefer flexible acrylic render to exterior but it can be painted. Interior walls can be painted just like Gyprock. 4) NO.....no additional lining is required. This is a major cost saving. Tiles can also be direct fixed....just like Villaboard. 5) Panels come with chases vertically & we're also looking at a horizontal chase at 2300. Chases are used for services. With plumbing, preference is that feed & waste is installed to the space through the floor. Where there is a shower etc, panels can be supplied without a MgO skin glued, allowing direct access to eps that can be carved out & also blocking installed. This requires forward planning of course. 6) Price is correct & includes bottom & top plate (steel profile). I prefer 90x45 timber as it's easier to work with 7) Hard question to answer as we wouldn't be in business supplying sub-standard building solutions. The MgO we use has been well researched. It is the intention to eventually have CodeMark compliance. Yes, the sound of rain is transmitted through the panel. My house has 150mm panels....heavy rain is quite muffled & would be similar to a truss roofed house with colorbond roof & excellent insulation. Garage roof is 50mm & the increase in noise is significant. Many thanks for your interest. there is a few calculators you can use if you just google it 7 7524 I can help you with all that, you can PM me with details if you wish 3 5821 I looked into it a few years ago and my conclusion was to just build a carport that will support panels and get a system installed separately.
