what are the dimensions of a roll? (need to work out if I can get them through my loft hatch)

My loft entrance is 48cm x 50cm. It fitted through that ok. It needed to be pushed through, it wasn’t slack but was not tight either, went through with out a problem. Hope that helps.

What is the length of the roll, please

About 5 meters max. Haven't measured it but that seems about right. I appreciate that this is not as helpful as you need but, well, I gave it a go.... Good stuff anyway.

What is the thermal conductivity of this product?

The recommendation for maximum conductivity is 300 mm, so it's about 75%. I have laid new rolls over old and as it's still warm weather, I can only give approximations.
