Thank you for your post @Temp No my father does not want to convert the loft space into a living area. It is just used for storage. The best way forward is for my father if he wants to increase insulation is just to add more layers of rockwool to the base of the loft and leave the loft void open to breath. Adding more rockwool insulation to the base of the loft would be like getting a thicker tog duvet to keep you warmer at night in bed 🙂

@saveasteading My main trade is Horticulture but I like to research things and learn new ideas. @Gus Potter Thank you for your detailed post it is most appreciated. I have read about spray foams for the loft and grants from the government and they have had some bad news recently. I would not advise my father using spray foams in the loft because there are risks as noted in your attatchment and the links bellow:- https://www.citizensadvice.org.uk/policy/publications/a-foamidable-challenge-tackling-the-impact-of-the-mis-selling-of-spray-foam/ https://www.bbc.co.uk/news/articles/cqjrpv218r0o https://www.theguardian.com/money/article/2024/aug/12/they-encouraged-us-to-insulate-our-home-now-its-unmortgageable Again thank you Gus Porter for your detailed information and post. If my father wants to increase the insulation then it would be best and safer to use normal loft roll as advised by @saveasteading and @JohnMo

Hello I am not a builder but I am seeking some advice please from people who know better than me on behalf of my father who is looking to insulate the loft to reduce heat loss so improving the heat retention in the house so saving money on heating costs. He has seen rolls of "SuperFoil Multi Purpose Wrap" on sale in Aldi for £9.99 a roll. It says on the aldi site that it is 3-in-1 bubble foil provides insulation and Reduce heat loss in your home. He wants to add it to the loft roof to stop the heat loss through the roof so making the loft warmer meaning the house is warmer. I have done some research on this and I have read that not only the "SuperFoil Multi Purpose Wrap" do very little to reduce heatloss through the roof (basically bubble wrap with foil on it) but it can cause more problems with damp and condensation build up. My personal opinion is that this product is more suited to outdoor heat insulation usage in garden sheds, garages, outdoor summer houses etc and not in the home especially for roof insulation but my father seems keen to use it in the loft which I personally think is a bad idea following my research online. If my father wanted to reduce heat loss in the house through the loft area would it be advised and better to leave the loft as a open, cold and well ventilated area, allowing air flow around the whole loft and the house cavity and keeping the roof open and not covered with insulation to reduce damp and condensation in the roof and house cavity. Instead focus on adding more rockwool type material to the floor/ceiling section of the loft to increase the insulation of the ceiling area upstairs so reducing heat loss in the house. The loft space is only used as a storage area and gets cold in winter hence my fathers concern about heat loss in the house through the roof during the winter months.
