Re: Thermal expansion in floor/vent landing design Jim, brick expansion based on saturated heat is something like .21 max. This is why those that are building the dome around the floor bricks are leaving 1/8 to 1/4 gap. As for the entry area, no gap occurs with wall bricks to floor because the heat is much reduced, although it still exist. The heat likely does not expand the bricks enough for such concern. I hope this answers your question. |
