Good product and the best price I have seen for a while. Grab your lorry load I have 8--)

EkoRoll Loft Insulation 200mm is a super top up layer for use above ceiling joists. It is compression packed to minimise handling and will expand to the required thickness when unwrapped.

We have i believe the old glass fibre type that makes me itch like hell when I go in the loft. If I strip all of it out can I just replace with one layer of this or do I need a base layer or two layers as the description says top up layer.

Same stuff mate just 200mm. The trick with loft insulation is to not allow it to flatten. The depth is key to retaining heat.
Leave your existing stuff in and lay this at right angles over the top of what you have. Get a mask, gloves and goggles along with a throw away pvc boiler suit. It will be a days work max.

This.

No need to remove old insulation.

I was thinking of getting rid of the old stuff as I will still come into contact with it if I mess with the electrics etc. in the future. Also it would hinder boarding sections of the loft if it doubles up above the joists.

Personal choice, if you want the best insulation just leave the old stuff and top up as has been said earlier laying it the opposite way

IF you remove the old insulation and out down 1 layer and then floor above it yes you will have a useable floor BUT electrics will be hindered in the future and it won't be as energy efficient, like I say personal choice.

2 layers going in opposite directions will give best insulation but you need to build up the joists if you plan on flooring it.
