Good product
Does exactly as described, well packaged and no bad value for money

Great insulation
Purchased at a good price when the 10% offer on all B&Q items was running. Really good value and does the job insulating the walls in my garage conversion. One thing to be weary of is that you can only safely carry 5 rolls on a flatbed trolley otherwise the rolls will fall off. This is also a little cumbersome navigating around the store as (for some reason along with timber), B&Q locate items like this away from the tills, so you have to wind your way around other shoppers.

Words alone cannot express it's greatness
It's just so slabishly woolly I want to wrap myself up in it, rub it all over and have its children.

Did the job at a good price
Unusually I bought this item for its acoustic properties . I have some very old (50's) loudspeakers which needed new damping in them and this was just the ticket wrapped in garden fleece. Sounds a lot better! It was very easy to cut and handle and replaced some cut up old duvet.
