Thank you Redbeard. I'll get on with ordering a testing kit. Yes, there is a 50mm gap under the current boarding. Would you expect to find a ventilation slot on the eaves for a house of this age? I have never looked to check. Will the gap in-between the slate and the super quilt be enough for ventilation at the roof level?

Hello everyone, I was wondering if somebody experienced could give me some advice please. My house was built in approximately the 1930's. We bought it 10 years ago. The roof has no felt from inside the attic you can see the slate. (see photo attached) I would like to make our attic dust free for storage whilst also making it more energy efficient. We are not in a position to replace the roof or lift tiles at this stage. I plan to do the following... I added a section on floor stilts (phot attached) last year and will carry this on to create a floor to stand on. End to end and up to the hangers. Underneath this I will add roll insulation on top of the existing. ( mixture of roll and loose ) Then I plan to staple 'Super Quilt' or equivalent to the inside of the rafters. End to end and down the hangers. Will seal with silver tape. Three questions I have is... Do I need to do anything on the outside of the hangers? There is already roll insultation on both sides. Does this solution work in terms of airflow prevent There is loose insulation under the existing roll, should I be worried about this containing asbestos? You can see it in the photo attached. Many thanks in advance and please let me know if I'm missing anything that I should be considering. Kind regards Pete
