Archways and ceiling kits vary. Most archways under 8 feet are 1 inch thick. Arches bigger then 8 feet are 1 ½ inches thick. Groin vault ceilings and barrel vault ceilings are always 1 ½ inches thick. Dome ceilings vary based on size and shape. All half circle dome ceiling rafters are 1 ½ inches thick while soft dome rafters vary from 1 inch to 1 ½ inches depending on size. Cove ceilings are generally ½ inch thick but will increase in thickness once the cove ceiling piece exceeds a 24 inch radius.
