Mixing Foil backed and mineral wool insulation

gtg60

Here's a quick one I would like some opinions on please.

I am insulating an attic this weekend, it is small enough (33 sqM), the joists are 100mm and 600mm apart, I am told that the attic will be converted in the near future so I have opted for 100mm thick traditional insulation so there's no problems for their future plans. I'm aware 100mm isn't great but they have nothing at the moment and there's no point putting in something that's to be ripped out whenever the attic conversion takes place.

I get a text from Woodies yesterday with a code that gives me 20% off everything, I'm looking at this product:
http://www.woodiesdiy.com/Product/ThermaWrap-Easy-Fit-General-Purpose-Insulation-600mm-x-75M/11624/6.3.0#.UvtV6Pl_s70

I'm thinking that I could use this product under the mineral wool and improve things greatly yet still keep the overall thickness to approx ~100mm so as to not interfere with the (later) attic conversion.

Any input welcomed, TIA.

Don't bother with the foil stuff. It will do nothing for you. If you don't believe me, check out its certification documentation.
