That's what I used to frighten my happyrentice with Barrie, if you don't pull your finger out you'll drill those accy eng brick with a star drillworked every time

You been at the Apfelkorn again?

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?

[heth]

No it becomes shiny G

the first time i drilled a wall made from nori's i wondered what all the fuss was about...

until my sencong attempt at drilling a hole didnt go through the cement and actualy hiut the brick.

thats when the makita hammer drill came out of retirement as i burned the black and decker out lol

They drill easy enough, these days we dont use star drills and a hammer like when you were a lad

That pic looks like the long stand I was sent to pick up from Bridges on Church Street, when I was serving my time

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!

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.

U value or K value ( Watt per hour lost etc) is a measure of how much heat is transfered through a certain material, a pilkington K glass unit as a U value of 1.5, a standard douvle glazed unit is about 2.6, the lower the number the better, a single brick will be poor, a modern house is built with an insulated cavity wall and the u value would be approx 0.25, hope this helps.
A nine inch solid wall would be approx 2.00

So that explains why people build their houses of wood in places like Canada and Siberia.
