Default Question about roof timbers

Will be? Seems to be make some presumptions. They could be any number of
sizes and spacings. They are more likely to be 4x2" on a 60s property.

foot intervals. But it depends on what you can drag thrugh the hatch. I


What are these for?

would suggest relocating the hatch and making it larger. Twin 18" doors
perhaps. as you are going to need to reinforce the floor and roof
joists.


Might be a good idear to ask what sort of loading is going to be imposed
before you go down this route.

The ceiling joists might well be 3x4s or 4x2s. Floor joists spanning 2
rooms will need to be 7x2s. It all depends on what span they are going
to be.


Again you can't know that unless you know the loadings, the spacings
and the span.

Check out a link for joists in the faqs.


Don't think there are any in our FAQ - there is some advice in the
approved documents (building regs) on the www.odpm.gov.uk site though.

Once you have a walk of planks up there, use a roller to give a quick
couple of coats of the cheapest emulsion to the roofing felt. Then
install a couple of 300W halogens. Or smaller wattage if you can get
them.

You next want to rewire and/if plumbing, the other necessaries.


Huh?

If it is to take a fair weight, the ceiling joists need reinforcing.
And that means more than the boards as they will be adding to the grief
the joist will be getting.


Have you been ghost writing for dribble lately? Can we have that again
in english?
