I'm replacing a hob in my kitchen and had to cut away some more worktop and remove the existing alu foil that sealed the cut away areas. When looking around to buy some more, I have found regular alu tape and also special worktop sealer heat resistant alu tape. Is there a difference between these products? Or can I just buy a roll of any old alu tape and use that? Screwifx only sells regular alu tape. http://www.screwfix.com/p/aluminium-foil-tape-silver-aluminium-50mm-x-45m/35529?_requestid=3917 Thanks
