| 778328 | 2009-05-30 08:30:00 | It is not my place .. the folks. I would think that the avg house may cost $30k to insulate? We may consider a heat pump for the main room tho. I have no idea what the actual cost are given enough time. Much like the problem of paying rent over borrowing and having a mortgage. Buy a heat pump which may save power for say 6K and save X over the time. Insulate and double glaze as well. Use solar panels for power or any and all. |

| 778330 | 2009-05-30 09:10:00 | Only problem with polystyrene beads is the fact they they would be an accelerant if you were ever unlucky enough to have your house catch fire... A chippie mate of mine reckons the Green Stuff stuff is better than Batts - holds it's loft better over time. I know the Batts in our ceiling are a lot flatter than they would have been when first installed... Plus the Green Stuff means that the installer doesn't have to wear protective clothing when installing - no glass fibres floating around... As regards polystyrene being an accelerant, I sort of reasoned at that time along the lines that by the time a fire burnt through 9mm of Gib plasterboard, then the house would be goodbye pork pie anyway. Another method of insulating the outer wall is injection of insulation through holes like zqwerty said. This is one firm: www.airfoam.co.nz I don't much like the idea of drilling hundreds of holes through the weatherboard though, which then have to be plugged, sealed, finished off flush and each repainted, maybe even the whole house repainted. It would make more sense in some ways to drill through plasterboard from the inside when re-decorating, and then plaster up the holes. |

| 778331 | 2009-05-30 11:03:00 | you will get good results by only doing outside walls and ceiling space. if you can DIY then you can save about 30% I don't know much about building. What are insulation in outside walls? I thought it was just wooden frames - horizontal and vertical the inside wall and the outside wall. Ie., if one has a leak, we knock out the inner wall and if we knock out the other wall we can put our hand and collect our mail? :confused: |

| 778332 | 2009-05-30 22:45:00 | I would still do each outside wall with either pink batts or wool batts but only as it comes time to decorate each room but I would do the ceiling immediately | gary67 (56) | ||
| 778333 | 2009-05-31 02:39:00 | Yep so far as I know, drill appropriate hole in wall, inject insul-fluff into cavity until full repeat until wall finished. I wouldn't consider using insul-fluff as over a period of time it condenses down and in walls that would mean you would get uninsulated areas. The air foam someone else mentioned would be much better and the holes are relatively small. I assume it is similar to what is used in modern hot water cylinders. |

| 778334 | 2009-05-31 04:52:00 | Sorry to be so slightly off topic - but Are all new houses supposed to be insulated in the walls and ceilings ? or is it up to the builder / owner / developer ? I hope so, as it means that in 100 years we will also have nice warm houses ! Ceilings are easy to do, walls as noted above are not so easy - they have nogs ! |

| 778336 | 2009-05-31 08:23:00 | By law all ceiling's and walls have to be done but not over the garage and all new houses have to have double glazing that one came in last year. Yes to do a wall properly in an old house you would need to remove the gib lining, but as I said if you do it room by room as you decorate it will take longer but be easier on your wallet | gary67 (56) | ||
| 778337 | 2009-05-31 12:20:00 | Much as I support the govt - any govt, when it moves to help people warm their homes, this is a vast problem for NZ and I suspect a bridge too far. NZ homes are poorly insulated unless built within the past 10 years. Even then the requirements have been modest. It goes back to our colonial heritage when the kitchen and living room - originally one big space, were the only warm rooms in a house. That attitude permeated building design until very recently. Retrofitting older homes is difficult. Not impossible but often too big a financial hurdle for most people. After all, if you can afford to do it, you can also afford a more modern house which is already better insulated. The best approach is to consider how and where heat is lost. In priority, roof - heat rises, then windows - they suck heat out, draughts under doors etc - but your house needs to breathe too (catch 22)..then walls, and finally the floor. The south side is the coldest and benefits most from insulation. |
