insulation

propertyrental

I've just measured the insulation thickness in the attic (newly purchased home) and it varies between 14 -17 cm.

I believe current recommendation is 270mm so I'll probably add another layer.

However my question is about the attic hatch, which has zero insulation.  There's a fancy access with a ladder that drops down, and to facilitate that the hatch swings down, meaning you can't just lay insulation on the hatch, as per my last house where the hatch could be lifted and slid to one side.

So what is the best way to secure some kind of insulating material to the inside of the hatch?

Ours has part of a water tank jacket stapled to the door. 
Was looking at taking that off & putting some celotex in it's place to give a tighter fit to the edges.

It's a small area. Pay more attention to sealing the gaps in the first place.

The hatch is a pretty tight fit. No gaps as such.

We used 100mm celotex cut to size and stuck to the hatch door with no nails.
We then spent some time ensuring that there was a draught seal around the hatch door.
All seems to work ok....although I don't think celotex  is fireproof !

You could create a simple and lightweight 5 sided 'insulation box' out of 100mm PIR insulation (Celotex) and have it sitting over and around the loft hatch/ladder (inside the loft).  When you open the hatch downwards and drop the ladder down you could just go up the ladder and lift the box up and out of the way and put it to one side in the loft.  When you exit the loft, move the box back into place and close ladder and hatch.  Hope this makes sense.
PS.  100mm PIR insulation has around double the insulation value of Rockwool type insulation

Surely that would depend on the position, location and the mounting points of the loft ladder ? The loft ladders we have fitted wouldn't allow for that design to work at all.

Like the other poster, get some celotex, cut to size and glue it to the hatch. Works really well. 
Then you can get foam like to improve window seals, and stick this around the frame where the hatch closes to make a snug fit.
