A good drop on these, they'd previously been on an offer that was 4 for 3, but are now £14 each. This one works out better for those that only need a couple of rolls in comparison to the old deal. That said, it's still cheaper to buy 4 here than other places as far as I can tell.

The two stars relate to the thermal efficiency of the product. This is loft roll 44, there is also a better, more expensive loft roll 40 product. The thermal value (R value) is 0.044 w/mk. To hit current minimum regulations for a new loft, you need a total of 270mm of this. 170mm between the joists, and then 100mm across the top.

I thought it was 100mm between joists then 170 on top?

Sorry, yes you're right. Wouldn't make much difference, it's just that the joists tend to be 100mm anyway.
