Hi Toby, no problem.
150mm of PUR is just about minimum here to meet code. You'll find that you'll probably end up in the same place in terms of minimum R value as us eventually, just takes years for things to change. Also another point. If you ever intend to run the underfloor heating from a heat pump you want the tightest possible pipe spacing throughout - generally 100mm. This improves the thermal transfer to the slab allowing you to run lower flow temperatures, which in turn increases the COP of your HP. |
