Made a mistake with loft insulation

Hi

Bought some Space Blanket loft insulation which I've never used before. In my haste I took the insulation out of the plastic covering before I laid it!!

Two questions:

Do I need to pull it out and re-enter in the cover? Hope not as I've thrown that away.

Can I lay the next rolls with the cover alongside the first one?

Assuming that it's fine but not as fine as with the heat resistant cover on.

Many yhanks

Prob best to post this query in Floors Stairs and Lofts Forum.

Thought you'd spot that.

Many thanks
