Hi Youngy73. So what sort of wall insulation should we be looking at. Our spec says R 2.5 ceiling insulation (except external roof areas) but nothing for walls. Why do they insulate immediately under the roofing and not above the ceiling? I can understand this in the summer as the heat rises into the roof space, but it also means that in the winter you lose all your heating or warmth there also. Any advise would be appreciated, as only used to dealing with solid block walls. |

The sloping site meant big bucks on the concrete etc - there's enough down there to hold up Fort Knox, and worth about the same.

Do you have any recommendations for sourcing your concrete? It is ironic but my brother in law is the GM of a large concrete firm in NZ (but the cost for frieght is dreadful;) )
I suppose we could have got a discount from your BIL and brought it in as cabin baggage but at a cost - and quarantine would have kept it until it was well and truly cured! |

Re: House building costs
Sounds right - IIRC our builder paid $175 /m3 - don't know if this included GST.

you should have better insulation in the roof than R2.5. some builders put it just under the roof and some on the ceiling. we live in the tropics so the winter thing aint an issue. Youngy73 & Wol, many thanks for your info. We plan to have roof tiles so will they provide better insulation? The whole roof and external walls will be sarked. Wall studs will be at 450mm centres. Does this sound ok. Anyone any advise on termite control? We will be building in Hervey Bay. Perimeter of house protected by vertical exposed slab edge. Penertration & control joints through slab protected by physical barriers (whatever that means) Wall studs & trusses: H2F envelope termite resistant framing. All termite resistant seasoned Pine. Many thanks Gillian |

Re: House building costs
Kordon is a double PVC type material with a thin fluffy inside treated with termicide - whole thing is about 4mm thick. Sits like a DPC and in theory the things either can't penetrate, or die in the attempt. Of course it can only be applied to the wall areas, so if the slab is cracked underfloor inspection is still required if the floor is suspended.

We are R2 for the walls and R4 for the ceiling, FWIW. Also can't remember, are you double glazing, and what extra % is that costing on top of single glazing at the time of install? Thanks for the advice. Buzzy |
Re: House building costs
I think R2 is the max for walls purely because that's the maximum thickness you can get into the frame.
You can stuff as much as you like into the loft, although R4 is the maximum that's sold - it's about 8" thick. I don't know what the extra is for double glazing, since we didn't ask for a single-glazed quote. But since double glazing is an alien, state of the art new invention here I imagine it's quite a lot more! |
