So, I've finally bought and moved into my new house and I know have a loft of my own! It's big enough to walk around in, is part boarded, but not very well and has some insulation down already but not much. A smallish hatch to get up and no fixed/folding ladder so a few things to upgrade.
I want to fully insulate it and board it out properly, at this stage mostly for storage, but a better hatch and ladder may lead to more regularly use. What do I need to consider if anything, before I start laying wool, floor boards and knocking up plasterboard?
Ventilation. Always consider ventilation or whatever you store up there may get soggy.
Floor boards and plasterboard? Are you going to be living in it?
Insulation should be 300mm I think, then if you board it you need an air gap between the insulation and the boards. You can get stilt type things from B&Q?Screwfix etc. To be honest ti doesn't cost much to get someone in to do it for you and saves you a load of faff as well.
If I'm going to do the job - might as well do it properly... If I can make the access better, then I would be tempted to work up there, it's a bloody big space and seems a waste not to use it for something.
Plasterboard is relatively cheap and easy enough to put up, it's also massively fire resistant. I'm thinking of insulating behind the plasterboard (so directly under the roof) as well with Kingspan or polystyrene boards, to essentially make a warm room up there. Which long term should reduce our fuel bills.

Don't block off the ventilation to your roof.
kingspan between the roof joists, use whatever thickness will leave a minimum 2" air gap below the roofing felt and then 35mm insulated plasterboard under the joists. insulated plasterboard isn't cheap but niether is kingspan, its easyer to put whats under the joists up in 1 layer
pretty much as the link above. wouldn't worry to much about trying to meet the u value though unless you've got a lot of space and don't mind spending a lot more on the insulation
