And southerners wonder why we built our houses on stilts...

Nope.

You need to go to a school of critical thinking.

There's a lot of mis-information being spread about the benefits of batts. Bit like the recycling myth. Here in Brisbane the general garbage and recycling stuff end up in the SAME truck, same muncher.
Re batts/insulation... if ya in a cavity brick house, they'll be of minimal ?no value in summer (if ya use air-con). In winter, they will help reduce convection loss through the ceiling if you have internal heating.

In most other houses, roof insulation will, IMO, be of close to NIL benefit. Once the sun goes down ya want to cool the place as quickly as ya can. That's best achieved by opening the windows.

On a similar vein, millions have been wasted by poor souls installing those silly whirly-birds on their roof. As useless as ...

Is this true??

You can substantiate this information. Do you treat Batts in wall cavities the same as ceilings? I have a verandah around my place with eight entrances (Four across the frontage, two side, one rear and one of bedroonm courtyard + floor to celing wind out windows, ceiling fans and ducted gas heating. Huge brick fireplace rarely used. Concrete slab with italian tiles, unfortunately ripped up the slate when refurbishing. Full length curtains with (pelmets are a must) also help.

So should I get the ladder out and rip out the 3.0 Batts (that was the highest rating 23 years ago) in the ceiling, not much I can do about the wall Batts, mind you I believe it was monet well spent. rant

Can't speak for other states, here in the ACT I know as does every other resident the refuse is collected seperately from the reclycling (paper, cardboard, plastics and bottles) I think entirely different contractors, one of the other ACT members may correct me.

I think you should stick to picking placegetters bleh

Most important things first - then I wanna go get some dinner or there'll be no placegetters for Dbn tomorrow.

There's been a pretty spectacular storm over the northern suburbs. Biggggggg sound and light show.

I reckon the tracks will have received 5-10 ml, so might be a minor downgrade of the track rating for tomorrow.

My newsagent got the insulation installer in, the dill stepped on the ceiling, went straight through, and landed, most fortunately, on a bed. sweat

Be a good job too in the hot weather, wouldn't it ? sweat

On the recycling issue, I'd be told that there was no longer separation of the two collections. Last Wed here I had the chance to confirm that. Standing in a gum tree beside my lean-to, I could see right into the aperture where the rubbish was dumped. The truck grabbed the regular refuse bin, tipped in the rubbish, then grabbed the recycle bin, and it followed in exactly the same muncher.

Whether the contractors "sort" the combined collections elsewhere, I dunno. chin

I reckon there's been many problems with householders using the recycling bins for regular refuse.

The electorate believe their doing the right thing, so the Council gets a tick for its commitment to recycling.

Not gonna rewrite Physics 101, but let's understand that there are three ways heat gets transmitted (gained or lost): conduction, convection, or radiation.

The simple principle of "insulation" is that it reduces any or all of these processes.

There's no question that insulation has a role in home construction, but the extent of its role will depend on many factors. Most important ones are the construction material (cavity brick, brick veneer, timber), location (Queensland, Canberra, Victoria), aspect, vegetation, local topography, etc.

Now, in Melbourne, where it gets bloody cold (at least it used to), the houses are sensibly built of cavity brick. The trick in Melbourne is to retain warmth from internal heating. Heating can be from a fire, air-con, or just body heat. The thicker the walls, the better. On a stinking hot day in Melbourne that construction will be a bloody problem because after sundown there's a huge thermal mass which retains heat, and provides discomfort when it's quite cool outdoors. Ya'd need air-conditioning (cooling), and there'd be some benefit from the insulation (either natural, or additional).

Let's come to Qld on a hot summer's day, when it's 34 at midday, but cools to 18 or so at night. What we want here is a reduced thermal mass, hence the timber structures of traditional "Queenslanders". As soon as the outside temp drops, the interior will cool rapidly. Ya don't want ANY insulation in such circumstances. It won't help during the heat of the day, and it'll retain heat during the night. There are now thousands of brick homes in Qld. Walk by one of the walls at night after a hot day. You'll get the gist. Ceiling fans might help in cooling the interior (but their value is often overstated as well, IMO).

In Qld on a COOL/COLD day, we want to be warm inside the house. Insulation will certainly help keep the place a bit warmer, especially if we're heating the interior.

My point is, to be sensible about insulation, and consider its limitations. Everyone who installs insulation will tell ya how beneficial it is. But they would say that.

5 mm of rain recorded at Dbn overnight.

Track will be perfect.

Plenty of cloud overhead but no rain in the offing.

Won't be as hot as yesterday I hope.

I've already done my outside jobs before it heats up.
