I need to top mine up, has about 100mm up there at most. That said though I'd want to board it out, whats the best/cheapest way to raise the floor to allow new insulation but also boards? Had a new loft hatch fitted and was warned that if I wanted to store up there I'd need cross beams to spread the weight, can I just put 47x100 timber up there with this in between?

I'd recommend a system like this.

loftzone.co.uk/pro…tml

you can get similar products from B&Q look for loft stilts. Then you stick insulation under and board on top. This way you aren't compressing the insulation down making it less effective. Of course it raises the level of the floor so there's less headroom....

Good price. I looked at earthwool because the usual glassfibre crap gives me a rash but this is still glass fibres.

Looks good, pricey though. Could do it in timber for 1/4 of that, but wouldn't have the airflow. Will have to think about this!

Check Homebase; they have a very nice 11.3m roll. I checked out similar at TP and it was almost £53. It's made of recycled bottles.

They don'y have it on show, by the way; it's in the warehouse.

Nice. Bought 4 thanks

you could use short blocks of wood with gaps between , say 4" long block , 16" gap, topped by a strip of, say3x2" timber - no need for 2x4's

I like your thinking.

not sure if this news about wool fitting relating to your project:

I read on news home ruined by 'Biblical' plague of moths

I have used Loft Flooring Legs in my loft to raise the floor by 175mm FROM TOOLSTATION. A low cost lightweight option.

Are you not suppose to leave an air gap between the top of insulation & bottom of the loft board when installing loft legs? That pic on Toolstation looks like it packed to the hilt with insulation with no breathing space for air to circulate.

You're not thinking of water tanks in the loft are you? you're not supposed to lag under those I think. I can't see why there's a problem covering the top of the insulation with boards but I could be wrong.

Yes, you should leave a gap. But it all depends on how much insulation you are using and how much headroom you want above the boards.

A quick google located this comment: "The point of the gap is to remove moist air. How much you have depends on how humid your house is and how well sealed your ceiling is, so not all houses will suffer this, but water vapour moves through the plasterboard ceiling, even if there are no gaps, and will cool as it passes through the insulation. So there's a risk that it will condense on the underside of the boards, causing damp and mould, which is why the BBA and BRE insists on the air gap. It's particularly bad in the winter, when the loft is cold. I've seen plenty of cases of boards getting so sodden that both them and the insulation have to be thrown away, and where fungus/water stains the ceiling and leaks down into the room below. "

Thank you. Ordered just in time.
