Loft insulation

taking boards up won't take long at all, I am assuming you are using a drill/driver and not screwing this by hand ?

Nothing to stop you leaving the boards in place and adding the insulation, legs, and new boards on top.

I am sure I read that this isn't recommended due to ventilation and condensation.

No drill/driver but I will be buying one if I put the legs down. I've got overclockers hands - much too nice to be ruined by screwing

100% get at least a drill, or even better, an impact diver. Eight screws per leg, sixty odd legs... That's a lot of screwing.

Just get a decent one from someone like Bosch/Makita/Dewalt and never have to worry about it wearing out or randomly breaking.

I put my (Makita) impact driver on top of a set of step ladders in my loft, I knocked it off and it fell through the loft hatch and landed on the tiled bathroom floor (cracked a tile) and still works absolutely fine.

whilst I love my impact driver, you hardly need one for loft legs/boards, and the drill/driver is more versatile for general DIY purposes

I`m thinking of re insulating the loft space and boarding out where not already done. Can I remove the old Yellow insulation and re insulate with kingspan between the joists, will the kingspan offer the same thermal insulation protection as the yellow horrible stuff ?.

I'm sure someone has already asked that.

Kingspan is harder to fit and far more expensive.

Yes it will offer the same insulation properties provided that you get the same U value.

Personally as horrible as the stuff is I would use the "wool" type stuff wherever possible.
Simply because as stated above it is cheaper and easier to install.
Got to be one of the worst jobs installing that stuff though.

On the subject of boarding, I've done 3 lofts now using 8'x2' 18mm T&G flooring rather than the fiddly little "loft boards" you get at most DIY places.

Granted they are harder to handle and you need to have decent loft access to get them up there, but I found it was much quicker and the floor was a lot more stable by virtue of the boards being much larger and T&G'd on all 4 sides.

You can get drill bits that fit into an impact driver if you need to.They have a hex bit end so just clip in
