Also, i'd strongly suggest you wrap the ceramic insulation edges with kapton as well as you can, or you'll eventually end up with flakes of insulation in your prints (that's from my unfortunate personal experience - i've insulated my Arcol.hu hotend and left the edges bare until i realised they shed little flakes and fuzzies).
