Roof curb for fitting around skylights, air conditioning units etc. on a sloping roof

摘要

The curb is formed from four side walls (12-18) that are interconnected to form a rectangle, with the curb being mounted diagonally on the roof so that every side wall is non-perpendicular to the down slope direction. An insert (26,28) is positioned at each of two opposed corners, each of which has a bottom surface that conforms to a profile of one of the roof seams, with the side walls adjacent the seam also conforming to the seam profile.
