From my preliminary chat with boss at MgO Panel Corp (MgO skin and either Polyurethane core or aerated MgO core) they appear to do the full 'kit' system where plans are made up into appropriate panels, services are channelled through the boards in the appropriate place. As far as cost I don't know how they would compare with OSB imports. Is there any issue about certification of imported boards for Aust Building Standards or do you know if there is an International Standard that covers Austr requirements. Reason I ask is there is a Canadian company Oasis which produce MgO skin Polyurethane core which works out about $40/m2. They are manufactured in China. Stewie D - had to smile - the advantages of SIPS is in part the speed at getting the walls up - 90% complete after a few years - the marketers would love that one! However it is good to hear that there is experience in that product out there. It seemed to me that the aerated MgO cores was a recent development from what the MgO Panel Corp fella had to say. cheers Re: Use of Structural Insulated Panels 69May 24, 2012 9:07 am In theory everyone can panelise the house into a kit at least that is what everyones marketing suggests. Reality however, from what I have seen, is a far different exercise and while success is easy on very simple single storey projects I know of plenty where it has been a disaster. Before spending any hard earned cash, ask for a few references from past clients with builds similar to what you propose. Builders are people too.... Re: Use of Structural Insulated Panels 70Jun 27, 2012 6:47 pm Hi Everyone, Average cost for face brick veneer construction external wall is about $155.00 /m2 PaneEco system is $50/m2 plus installation max $20/m2 i assume this, plus external render $25/m2, plus internal joint set $5/m2 That's a saving of $55.00 /m2 for external walls, plus saving for roof and ceiling which is another $40/m2, there is no saving for internal walls compare to timber studs. So on average 4 bed house i cant see how you can save more then $20,000 ? Has anyone compared real costs to brick veneer construction, and how much you can save? Quicker, it probably is quicker and you get better R value, but its going to be hard to convince clients to go this path. Any other builder offering this to their clients? Re: Use of Structural Insulated Panels 71Jun 28, 2012 9:11 am all the SIP suppliers tend to claim that their product saves $$ on building cost. However, in reality, you are up against the `novelty penalty' imposed by builders and unexpected costs of special fittings or renders. we had quotes for a custom designed ~180m^2 house with slab on ground - $340K using Bondor Insulliving versus $290K for the same house in brick veneer with timber framing! Re: Use of Structural Insulated Panels 72Jul 01, 2012 11:17 pm Prettygully Possibly the point you are missing is that if you are considering building with sips, then you are probably innovative enough to find alternatives to the standard cladding on the outside, and gyprock on the inside - maybe removing 2 trades and replacing both with alternative "green" cheaper solutions. If you do build in brick veneer and timber which will you have on the outside? Timber I hope - or you will defeat the purpose of this style of building. I will be building a sips house - floor,walls and roof in a few months. The sips will be osb-eps-osb of varieing thicknesses according to need. The roof I am going to prime and then paint with a waterproof uv reflective roof paint which will deflect 90% of the suns rays - 1/2 the cost of a basic colourbond roof, and a 1/4 the cost of colourbond maxicool reflective iron. The external walls will be primed, waterproofed and painted with a lime based "natural" paint guaranteed to last the life of the building or 100 years whichever comes first. Both applications I can do - I'm not a professional, but have boned up on how to do it. The cost saving in these two areas alone is very substantial. There are many many more far more interesting ways to go about this than the standard that has been around so long that it bores you rigid! Have fun Jeff Re: Use of Structural Insulated Panels 73Jul 04, 2012 11:26 pm Jeff, Have you any links to websites for the paints you are going to use? Here is a link to my photo album for the SIPs build we did in the UK. 9 days for 2 of us to erect the wall panels and 1st floor I-joists and decking !! http://photobucket.com/chardselfbuild Enjoy, Justin Our build thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=64997&start=40 Re: Use of Structural Insulated Panels 74Aug 16, 2012 2:33 pm Just signed a contract this week with a regular bricks and mortar builder to build a home extension in suburban Perth in SIPs. Extension will be 3 beds, combined living / dining and a bathroom - so pretty substantial (don't know sq m off the top of my head), and we are paying approx $50,000 more in a $500,000 build for SIPs. I'm informed that it's not the cost of SIPs that push the cost up, it's the cost of what comes with it - plasterboard interior lining (apparently more expensive to install than float and set, the norm for brick construction?), and battening and boarding the exterior. I'll let you know how it goes, and in 6 months you can come over ahd kick the tyres (metaphorically). Re: Use of Structural Insulated Panels 75Aug 16, 2012 5:07 pm That 10% premium is pretty standard additional cost if using the WA manufactured panels as they are very expensive. This whole SIPS sector of the building industry is undergoing rapid change and there are now very reliable suppliers from the US who we are able to import with and more cost effective (and I believe higher quality) than what anyone is producing in Australia. While I take the earlier point that the additional costs are the 'novelty factor', to be fair the cost of these locally made panels are exhorbitant. Also, what the novelty factor really means is that the early adopters to SIPS (ie: the home owners paying for it) are effectively paying for everyones learning curves as there is a lot to learn about the design, engineering, cartage, installation, erection and fitting off a SIPS house and these learning curves apply to all the trades involved - not just the builder and the erection crew! I have also recently been introduced to a polyurethane foam panel with OSB both sides that is currently undergoing testing and this panel is achieving the highest energy rating of any SIPS in Europe. THe point here is that this whole sector is very fluid and under constant change but I personally believe that SIPS building is here to stay and will only get bigger as it becomes more cost effective. Builders are people too.... Use of Structural Insulated Panels 76Aug 17, 2012 12:01 pm chardy We built our 2 storey house here in the UK 4 years ago with SIPs for the walls and found them to be a great system. 2 of us assembled the whole shell including 1st floor joists and boarding in just 9 days with no prior experience. Our SIPs are OSB face both sides with a 100mm Polyeurethane core, any supportive beams are Glulam. Inside we battened out to create a cavity for cabling/plumbing before plasterboarding the whole lot. Outside has a membrane then battens supporting a brick tile cladding system so looks like brickwork but isn't ! We move over to Perth later this year and would love to self build (owner build) again using SIPs but most companies in Australia seem to only do EPS cores which I am not keen on and not as good as PU in my mind - anyone know different or shall I set up a factory myself ?? Justin Chris here (bensdad aka pio) we are using an r9 panel system in Perth to build with we also use afs as well. I'll pm you the details. PPA 30/6/12, Land 28/06/12, Contract 7/9/12, Valuation 11/9/12, Prestart 13/9/12, Settlement 18/10/12, Building Permit Issued 18/10/12, Footings 30/10/11, Slab 31/10/11 Re: Use of Structural Insulated Panels 78Aug 21, 2012 2:14 am Steel, We ran our cables behind the plasterboard which was battened out from the SIPs. I'm not a great fan of chases through the insulation ! Builda, Good to see a OSB-PU-OSB panel may come on the market, nothing but good reports from me after 5 years ! Chris, Nice one, look forward to seeing your build when I get there ! Our build thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=64997&start=40 Re: Use of Structural Insulated Panels 80Aug 25, 2012 6:36 pm 2 ways to do it here but it depends on local electrical regulations as to which is suitable. 1. A layer of plasterboard onto the SIP with gaps left for the cable drops then another continuous layer over the top - gives a more solid feel. 2. 25mm vertical roofing battens at 300mm centres and plasterboard over the top giving a nice clear cavity for the cabling. Hope this makes it clearer !
