My loft does is not adequately insulated and a significant proportion of
it is boarded out. The energy saving trust pointed me at the above
product. Anyone used this? It is rather expensive so I'm canvassing
views right now.

Thanks

Have never used and would never use as it is highly unlikely that the
claimed results would be achieved in a typical installation. Same
applies for all the foil/metalised plastic sandwich and bubble wrap
products.

The only insulation product I would use in a boarded out loft is PIR
foam board such as celotex, kingspan or ballytherm. It has the greatest
insulating factor per unit depth of any domestic product and is proven
to work with just a little care in installation. Buying seconds with
cosmetic defects can offer significant savings over pristine product.

in a similar situation to you and so was looking at this but it appaers
quite expensive it appears that you need 2 layers + 20mm of some sort of
pir foam board to get the eqivalent of 270mm depth of rockwool.
at least according to

http://www.ecohome-insulation.com/fi...Insulation.pdf

or 1 layer + 60mm PIR foam board ... to get a u value of 0.18 (about 160mm
rockwool)

I have just bought a load of seconds on 60mm PIR boards (£3.25 for 4' x 2'
boards) and will lay thopse on the boarded areas with hardboard on top

to bring the U value to the equivalent of the recomended 270mm rockwool you
really need 100mm of rockwool and 80+mm pir board but cant afford that :-(
