Insulating solid walls

[Anonymous]

What you are describing Mike, in building design, is called thermal response. The dense concrete block simply absorbs more energy than the lightweight block. Take two houses; one made from solid, dense stone or block walls and another from lightweight aerated blocks. Come home when the house is cold and turn on the heating.

The dense blocks absorb a lot of the energy so the stone house takes longer to warm up. But then of course it releases the warmth for longer after the heating is turned off - the house acts like a thermal store. But of course some of that warmth is released to the outside not the inside - so you don't benefit from it all.

Now take the lightweight block house. The blocks don't absorb much energy, so the house gets warmer a lot quicker. But after the heating is turned off the house also gets cold much quicker. Although you don't waste as much energy to the outside.

So; older houses take longer to warm up but stay warmer longer. Newer houses warm up quickly but get cold quickly.

The humidity from the inside air will not come through the aluminium. Where will it condensate? You will produce mould attack by such means.

The Fraud with the U-Values

I know these arguments from my discussions since years. Try to find out any product of your mentioned physical terms to find out the given results of my experiment. Good luck, I gave up.

Naturally we continued the time range up to 2 hours, no difference besides the thermometer of the mineral wool came out of range.

What is important: The materials differ in cellular structure. As more cellular refraction-, reflection-, absorbtion-, scattering-effects to the IR-radiaton as more it stops the wandering of the temperature as function of radiation. I hope, you can follow my bad english.

The Hoax of the U-Values

Regrettably I didnt understand your english this time on any of those 3 points.

I understand you say youre familiar with these statements, but I dont know what it is you ask me to look for. O level physics teaches specific heat capacity, toddler experience teaches absorption of IR and so on.

Sorry for my bad english. What I want to say is that the values of heat capacity (and others from 'typical' building physics) can not at all give results as I got in experiment. The only reason recording to my experience and knowledge must be in the different structures of the materials referring to the transport of IR-Radiation.

A good analogy for IR radiation waves would be visible sunlight. Both are electromagnetic. Sunlight will penetrate 'light' structures as polystyrene and glassfiber, if you prove it with a 1 cm plate, and what will happen if you take solid wood or brick as plate? You know the answer.

Besides, sunlight will also penetrate simple window glass, IR radiation of warm surfaces will not. So it is enough with simple glass panes, you need not more to store your warmth in the house. The old masters did know this, modern glass industry has only forgotten ;-)

The added figure shows how electromagnetic waves will penetrate glass or not.

I was suggesting there are several issues with your graph, not only one.
