Not so long ago there was a thread about venting the attic to get rid of the hot air to cool the house etc, well, while thumbing the dreaded "screwfix" pages, I saw shiny "buble wrap" and wondered how good it is at reducing radiated heat (and cold) from the roof tiles. Looks like just the job to keep the attic cool(er) in the hot months.
Is it efficient? does it work the way it say on the tin?
