Insulation material (7)

Ross

I believe the answer is:

lagging

(Other definitions for lagging that I've seen before include "dropping behind" , "Insulation -- failing to keep up" , "Insulating material" , "Getting behind" , "Wrapping used to prevent loss of heat" .)

I've seen this clue in The Sun.
