I brought my house 6 years ago and whilst the loft was insulated it wasn't great. I have now had the roof tiles replaced so decided to look at insulation. After reading a number of articles alot of people said it was best to overlay old insulation to increase depth rather than replace.

I brought just 3 rolls to try over one of the bedrooms. I have layered at 90 degrees to existing insulation and have found a huge difference as such the room is warmer. Iam now playing to take up boards and do the same over rest of loft

I bought this a week ago. I've unrolled and left as single layer yet still the insulation hasn't expanded to 100mm. Averaging 50mm which means it's £36 for 8m - Not the £18 I paid. Easy to use. Easy to work with but pointless and expensive if not meeting the 100mm stated. Will double up for a small area of my loft and buy a different product from elsewhere to finish my loft.

This product is excellent in that it contains no potentially harmful fiber. It is however incorrectly described. It is compressed on the roll but when unwrapped it is only 50mm thick not 100mm as described. I have left the product unrolled for 48 hours hoping that it would continue to expand but there is no change,still 50mm. This is very unsatisfactory and I'm surprised that a reputable company has made this error.

The house is warmer now. The insulation was easy to fit. I should have purchased wider insulation to fit between joists. It was an inconvenience that the insulation was wet when I got it home, it must have been stored outside.

Great product

Bought this today in store after seeing it and thinking it would be ideal to use in the van to quieten the load area down. A lot of the rolls were wet when I went even though they are covered in the outdoor area. It’s great as it’s not itchy yet fills the sides of the van nicely. I did fold it over and one roll did the sides and rear door of my mk5 Astra van with about 300-400mm left. Would recommend it to anyone with a campervan etc as it’s warm in winter and cool in summer hopefully whilst keeping road noise down. Much cheaper alternative to the sound deadening stuff at auto shops.
