Putting in loft panels?

[purpleroad]

Got these tongue and groove loft panels. Worth clipping them together or screwing them down into joists?000

I just screwed mine never seen clips used

You can buy a box of loft panel screws in b&q that includes a drill bit
If you can, have a drill and a screwdriver so less bit swapping

Just been screwing in 2 Inch screws into joists. Didn't bother with pilot holes. Hope this is all good? I checked for wires. The extra chip board will screw in as well

Can u throw boards further back into loft

You've gone the wrong way across the joists, but I don't think it'll be a real problem, and 2 " screws should be fine. The real problem is that you won't have the right amount of loft insulation under the boards, hence why you either use loft legs, or add a 75mm packer to the joists. It's not sure what's aftet the steel rsj, so we can't comment on going further back.

It's no different from before. The boards weren't on loft legs. Do many people use those?

After the RSJ there are beams or joists running across bur they are much lower down compared to the joists near the entrance. The insulation is higher than them. Would they be safe to throw some chipboard on ?

I really don't like the loft legs.

In the past I have counterbattened with 2x4 or thereabout. When screwed down well they stiffen the deck somewhat and reduce the risk of ceiling cracking.

Today I might put rigid foam slabs over the existing roof timbers to give the required thickness of insulation when added to the mineral wool between them (foam has about twice the insulation as the same thickness of fibre) and ply over that, screwing it through into the timbers.

I'm not keen on chipboard, especially anywhere that might get damp.

I've considered using decking board to floor the central walkway in a loft, they are strong and cheap.

As JohnD suggests, bring the height up using battens (2x1, 2x2, or 2x4) to get them up to the height you want, and throw a bit of wood glue under them before you screw them down. Water resistant chipboard is better than the loft board stuff, but as long as your loft is dry, and there are no leaks, then the loft boards shoul be fine. I glue the edges as I go, and if you end up with a join inbetween 2 joists, then screw a supporting batten underneath the joint, and across the the joists.

I used the LoftZone StoreFloor system - it's definitely the expensive option compared to either nothing or the loft stilts that I've seen in B&Q. However, what I have been left with is a very stable flooring system that I'm happy walking across (and a lot of insulation underneath it).

And as has been mentioned, the current panels are being laid incorrectly (i.e. parallel to the joists, rather than across them)
