Heat moves from hot to cold, not the other way around.


The secret of insulation is that the insulation causes the heat to move slowly, very slowly or VERY, VERY slowly. One inch of solid wood has an R vanlue of near 1, so wildie's R50 roof is the equivalent of a roof that is a solid piece of lumber 50 inches thick, sequoia, I presume.

Aha! But. There is always a but isn't there?

Unless you have a vapour barrier between the insulation and the attic all you have is a giant filter. Every nook and cranny now is sealed off. Fiberglas is porous.

Even the electrical plugs in the wall are sealed now. Just piling insulation on top of the attic boards will work to a certain extent but that's not the real answer.

Yes it moves slowly but it eventually gets there doesn't it?

Our province once had an aerial infra red camera picture taken of all the houses in the city not individually but you could zoom in your house.

It was easy to tell which houses were losing heat.

Let us clarify. The soffit is the part covering the underneath part of the eaves.

And in Canada we use eavestroughs to carry away the water. They are hooked onto the boards that are the front of the eaves.

I think they are called fascia boards.

Our water run off goes to gutters, attached to edge of roof, and then down pipes . If you live in most of southern Australia this water will be piped to rainwater tanks which can be used on the garden or sent back into the house for flushing toilets etc. Far north west Australia eg Broome have no gutters, because when the wet comes it would flood and overflow. Their roofs (?) just let the rain runoff to the ground.

Well here the water table is quite high.

We try to direct the water away from the basement walls. We have what is called drain tile at the basement foundation level to collect water which is then sent to storm sewers or just pumped outside to water the lawn.

The fear for people with basements is flooding. Huge damage if the storm sewers can't handle a heavy rain.

Canadians call gutters 'eavestroughs'.

Its Fred's roof that is R50, mine is only R40.

Nice diagram. The soffit vent? I had to install my own there was none to begin with and the insulation blocked off the air getting into the attic. Had to go up there and install U shaped foam plastic to clear the pathway to the attic. Now they have neat aluminum vents .

Yes but you need a special drill combo for those round ones. Called a hole saw.

Right. So is a drill used to make 'holes' right?

The hole saw has a drill in the middle of it . The saw is on the outside looking in. The good ones are not cheap.

And the cheap ones are not good. I think I got my set at the Dollar Store. For anything up to an inch I prefer a spade bit.
