What is the recommended or code requirement for finishing the bottom edge of exterior rigid insulation?
On the exterior of my home I plan on using 1/2" OSB, 1" rigid insulation, with 1x4 furring strips (and insect screen) creating a drainage plain, covered by fiber cement siding. I wonder if the fire code deals with this specifically or not? (Leaving the bottom edge and the drainage plain open to the bottom side.)
You have really the best articles dealing with exterior insulation and drainage plains, but I don't recall seeing if leaving the bottom edge exposed is OK or if it is better to put a drip rail under it, or what some other solution might be?
