Polystyrene is not as good as Celotex/Kingspan,,i am not sure if the same applies for inside the hive but for every 50mm thickness of Celotex you need 100mm thickness of polystyrene to give the same benefit when insulating a house..also the Celotex has the sides already coated in foil so you only need to tape the exposed edges once you have cut it..
Patrick No that tape is not to deter wasps.. ...it is all i had to hand at the time when making them..i normally use aluminum tape but i had ran out of the stuff...the little protruding screws on the top bar side of the insulation are to lift them out instead of digging my hive tool into them..
