Prevent heat loss (8)

Ross

I believe the answer is:

insulate

(Other definitions for insulate that I've seen before include "Protect from heat, cold, noise etc" , "Cover or protect with a utensil (8)" , "Protect (from, eg, heat)" , "A utensil (anag.)" , "Cover with material to prevent loss of heat" .)

I've seen this clue in the Sydney Morning Herald.
