I have started building a grill in the garden. I have built the leca foundation on which we will cast a concrete slab and then build the grill itself (plus incorporate a sink, etc.).
I'm considering building the grill (in the shape of an upside-down square U) with 19-hole chimney bricks, lined with firebrick on the inside. Then I will place a sheet metal chimney on top of the whole structure.
Does it seem sensible to skip leca in the grill area? I've gotten the impression that brick is more heat-resistant and less prone to cracking than leca in this context.
Perforated brick versus solid? It sounds like chimney brick would be ideal for a grill, though I haven't understood the purpose of the holes other than reducing weight...
There's a lot of air in a grill, said my chimney sweep, so the heat on the stones isn't a big problem, so I took lecablock and set fireproof around the hot area, works perfectly.
Have reached the masonry stage now. So building the grill (like a square U from above) on top of a 55mm concrete slab that stands on a lecamur. Beijer facade and concrete recommend chimney brick, perforated. The part used above the ridge in a chimney should be frost-resistant. Unclear why you see recommendations for solid brick for things like grills.
The thing with massive above is probably a bit too much for rain and moisture, it stands outside and can get frost damage if they are hollow, all chimneys are solid brick on the warmest part, although I haven't personally built a chimney, I've only seen how they do it, and I followed the chimney sweep's recommendation.
Well, then it seems like going massive is the way to go anyway? It will be both hot here (when grilling, although lined with fireproof bricks) and exposed to rain and moisture.
I would have preferred to build with cheaper/lighter hollow bricks. Hmm...
You can also put a spirorör up as a chimney and build a frame around it, preferably with a hat on so it doesn't rain in and wet the inside. Then you can use håltegel; according to my chimney sweep, it's fine, there is much air and less heat.
Absolutely, a metal chimney will be installed, according to the borrowed image below. So it will be protected from rain to some extent, except at the bottom near the concrete slab. I'll take photos at home and upload them later. This is a question I haven't solved yet, whether to create a small fillet joint with B-bruket under the first layer against the concrete slab that protrudes a few centimeters. You don't want snow/water to get stuck there and then freeze, damaging the joint.
It becomes a bit difficult with the material there, the heat, and if you use a clay-based compound, it can absorb moisture since it's outdoors.
That only applies when it's neither freezing nor thawing, maybe a couple of doors that open so they go around the corner and rest against the gables.
Then it becomes completely open in the front.
