Accy nori?
Does anyone know the U-value of Accy Nori bricks, i have been on google and ask, but they keep coming up with the same answers

Re: Accy nori?
its to do with how much the bricks resist water i think

I do know that Nori supplied all the bricks which went into making a long large diameter tunnel through Erdington, Nr Birmingham. Gilbraith Haulage took many thousands of the things all hand loaded and unloaded. The bricks all had a slight curve in them to make a snug fit when they formed the pipe. I am sure they must have been water resistant and most certainly acid resistant other wise the mucky wet stuff would seep out into the ground around the tunnel.

My dad who worked at Nori for years always told me they were waterproof as well.

Any of you lot ever eaten nori?

What does U-value mean?

Re: Accy nori?
i think unless you drill or break them they are waterproof.
leave one in a bucket of water for a few hours then smash it and see if its dry on the inside :D |

If the brick is heavier it's absorbed water, if it's the same weight it's waterproof. Nah, not as much fun as smashing bricks is it? |

Is it true that if you soak one in Coca-Cola overnight, it will have completely dissolved by the morning?
Or is that a hen's tooth? |

Re: Accy nori?
As I remember, 'U' value was how well or how badly a material transfers heat. A wooden handle on a hot pan transfers badly(so keeps cool), a metal handle-ouch. It was nothing to do with water resistance. Nori bricks are so dense they would transmit heat badly and I would guess they are waterproof also.I think 'U' values were used for engineering and building materials.e.g how well would a house wall keep heat in.
Nori- the only brick that needed a new masonary drill for each hole! |
Re: Accy nori?
Google it-Coefficient of Thermal Conductivity. i.e how well does a material conduct heat.
Expected conductivity of a brick wall-0.77W/M-K. Don't ask me to explain that(can't remember) but the lower the number the better. I would imagine Nori is lower than that but if you need to use a number quote 0.77. Why on earth do you need to know? Just interested. |

Re: Accy nori?
So that explains why people build their houses of wood in places like Canada and Siberia.
