Preparing for loft insulation

[fatblokish]

'tis hard work. As we use the loft for storage, I'm having to raise the joists by 200mm using timber stilts.

250 or so of them. Cheaper but harder work than using proprietry stilts.

Off to have a bath now.

Hi
Do these stilts screw or nail into the joists? I might be doing this job myself soon. Where did you buy the stilts from? Thanks

Argh, my sympathies. I laid insulation crosswise over and above the joists--I'd hate to have to go back and relay/deepen/generally make room for extra insulation and reflooring.

Errr ......... stilts? You need to lay joists across the existing ones for strength and to spread the load. I did this about 7 years ago and now have a very thick layer of insulation. The house now stays warm for a lot longer and requires much less energy to heat. I laid 3/4 inch chip board on top of the new joists so I could store stuff in the loft. It was a bit a of faff but I enjoyed doing it.

 

[Canrider]

Do you mean across or along? I thought you were meant to lay extra wood along the length of the existing joists to 'deepen' them to hold the extra insulation. As in, existing joists are usually about 100mm deep, so to get up to the current 270mm+ code you'd need to make those joists into nearly triple-depth in order to 'hold' the insulation batts.

 

[Crankarm]

Across, not as you describe.

I don't want to be a killjoy, but according to amnesty international most insulatory material used for forms such as house insulation is made in bangladesh in child horror factories that were exposed by Richard Hammond on the BBC about 3 years ago.

The factories are being closed down now so I'd give it a couple of years until everyone is happy again.

I have laid stilts (I call em legs). The existing layer of fibre-glass roll is laid between and parallel to the existing 90 mm deep joists, the new second rolls of fibreglass will then be laid over the top of the joists perpendicular to the original (recommended to cross-ply like this). As for raising the height of the existing joists, I have used the stilts method. The new insulation will need to be perforated to accomodate the stilts.

To Crankarm: I have used stilts in preference to laying additional joists to reduce the extra load on the existing joists; the stilts are much lighter than whole joists. Both methods distribute the load imposed by the chipboard in exactly the same way.

To Maz. The stilts are 200mm cut from a 3.6m length of 50*50 sawn treated wood from my local timber merchant which works out about 25p for a 200mm length. I then screw them down using these http://www.bkservicesonline.co.uk/s...d=6262&zenid=836551aedd8a0e5234aebfd701b036f2 which cost about a fiver for 50. Plus 4 screws per leg at a penny each totals about 50p per leg. I have also used some angle brackets to resist any turning moment imposed by the legs.

Proprietry legs such as http://www.toolstation.com/shop/Con...k/Loft+Flooring+Legs+175mm/d210/sd2797/p44016 cost a little more. I am from Yorkshire.

The legs are positioned at about 500 mm centres.

Those look like the unfinished crucifixes of the bangladeshi kids who make the cancerous material. boo...

I did the 'across' method as well.

In empty attic we laid insulation between the joists, then put in about 10 joists double width across the existing joists and laid insulation between them, then held it all together with chipboard T&G boarding.
So in effect we have a false floor.

A false floor in which to bury the corpses of the bangladeshie child insulation makers. All dead to help us keep warm.

But surely cutting my CO2 emissions will reduce the impact/frequency of flooding in Bangladesh? To me the stilts resemble the shoots of success growing from the flood plains of the Bangladeshi deltas. Hurray !

If you turn the stilts upside down then they represent swords of damocles hanging above our mortal flesh-heads and our consciousnesses.

Turn around touch the ground, no comebacks.

Yeah, right...the horror factories of Bridgend. Hello...

I don't have time right now to google whatever you have stipulated. And neither should any human under the human rights acts.
