I'll start with one I through together for a client last year.
Was that a kit?
I sure hope that block is rated for use with fire............................
The construction looks nice, you did a good job.
But man oh man......that sure does look extremely LEGO-EY. The modular block industry has it's place for some things. Then there are other things where they just need to staw away.
Finished this one last fall.
Looks good man! I'd like to see it lined with fire brick but than who gives a **** what others think.
I was under the impression that only materials rated for fire (high heat) could be used. Cement (portland) based materials cannot withstand high heat. Additionally, they are air-dried and not kiln fired. Water trapped (absorption) in the material can have detrimental consequences when high temperatures are applied. An air-gap with a fire brick lined box is safer.
Our chimney was built using a Hutch Chimney insert. Basically a pre-built metal fireplace set on top of fire bricks. We then built around that using blocks, there is at 6" between the insert and the block in all directions. No adhesives are used either everything is held together using Fire-Stop Mortar.
Before I read Casper's most recent post I noticed the metal liner inside. Kinda interesting.
Casper, might you have any pictures of the fireplace during construction? I'd like to see how it's all assembeled.
I really do not like this modular block idea, but that doesn't mean we won't do them.
I do not like this idea of mixing concrete products and fire. Many many moons ago in shop class a guy was working with a cutting torch. The heat from the torch caused the concrete floor to explode in his face. I burn piles of brush on my property, and the land is infested with alotta natural rock. Well, when the fire is alive and burning you get pelted with pieces of stone!
DVS these are the only two pictures I could find and they do not do much justice. One mainly only shows the flue, the other shows a bit of the insert, however it was before we decided we did not like the way it was starting too look and ended up tearing it back down.
Also agree with you on the block. We were told using the insert and the precautions that we used the block will not have any problems. Time will tell I suppose, this is the first one we have built, I guess its one of those learning experiences.
Here are a couple pics of one that I'm building in my back yard. I've been working on it for about a year and a half - in my spare time. Seems like my only spare time is when it's freezing cold or blazing hot, though. The second one is as far as I got before cold weather caught me.
