Browse Forums Heating, Cooling & Insulation 1 Mar 07, 2017 9:53 pm With Sydney weather seeing occassional 40+ degree temps and cool temps in the single digits in the peak of winter, is the standard offering from most project home builders adequate? Or have some other forum members upped their R-Value and ifso, at what cost? Cheers. Re: How much emphasis should you put into your R Value? 2Mar 07, 2017 10:07 pm probably the biggest change for me has been to limit the window sizes. This was a no cost change and increased my last house by almost a one star rating. For more check this link: Window Size Comparison The Harder You Try - the Luckier You Get !

Re: How much emphasis should you put into your R Value? 3Mar 07, 2017 11:06 pm I asked for the maximum amount of insulation in wall and roof when in contract stages, it was actually very affordable, less than 2k for a 50sq house from memory.

Hi Gravy, Sounds attractive! Do you know what the original R-Value of the home was set at before the $2K spend? And what rating did it achieve in the end? Another question for you is: Did the $2K cost actually add additional materials or was existing materials upgraded?

Another question for you is: Did the $2K cost actually add additional materials or was existing materials upgraded? Cheers I can't quite remember what we had in the walls (R2.8 maybe? I do remember them saying there was a limit due to the cavity size) but I know it's R6.0 in the roof. I have it written down somewhere, if I find it I'll let ya know! Also the 2k was upgrade, not additional.

Many new home designs have large glass areas that can open up to alfresco and back yards with a strong notion of open plan. In a 2 storey home, with lots of glass on the ground floor living area, is this counter intuitive? (Mutually exclusive) Trying to keep the house cool in summer and warm in winter? Re: How much emphasis should you put into your R Value? 8Jun 01, 2017 11:40 am Definitely worth the upgrade. Just about the cheapest bang for your buck to build a comfortable,energy efficient home. The other thing that's important, which you can often do for free, is orientate your house correctly. Choose a design with north facing living areas. It's called passive solar design.

With insulated external walls and sound proofing selected internal one, would anyone 'upgrade their HVAC ducting to thicker INSULATED DUCTING'?

With insulated external walls and sound proofing selected internal one, would anyone 'upgrade their HVAC ducting to thicker INSULLATED DUCTING'? It depends on whether your ceiling space is insulated or ventilated. On a stinking hot day the heat in a ceiling would permeate into the ducts resulting in the system working harder to cool due to the warmer supply air. They make the room much easier to clean for one, reflect more light (if light colour tiles are used), and you dont end up with dust on the top edge of tiles (cause most… 3 9594 As a tradesmen get a private inspector although I don't think there worth it in their profession themselves the reminder they serve to the tradesmen doing the work is… 3 27360 The last home I lived in didn't have a pool and when i went to sell it the agents were not happy, even telling me to put one in to sell the place.
