Thank you all . I will contact installer as I can't do it myself. Foam sounds a perfect solution. My loft is empty as I wouldn't have anything put up there . Made that mistake in my old house. And forgot so much stuff was up there until I moved. Took my son a whole day to empty it . And it all went to the charity shop. Though after being up there 20 years if I didn't need it in all that time it could just go. Didn't even look in the boxes.
Thank you again
