This insulating inner dome clips inside your existing Icon SL1422 skylight outer dome to create a dead-air space that reduces condensation and helps stabilize interior temperature. Made from white ABS plastic with a clear centre insert, it measures 24 by 16 inches and installs tool-free in minutes. Condensation buildup on the outer dome is minimized because the inner dome keeps warm interior air away from the cold outer shell.
