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.

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 !

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 ! Our build thread: https://forum.homeone.com.au/viewtopic.php?f=31&t=64997&start=40 Good questions but the best answer will be obtained by visiting (ie: interviewing) a couple of house designers and/or builders and ask them.

There maybe should be an additional J1 between TB10 and T12 if… 3 31824 |
