Timber spans
Hi,
Could anybody who has access to the regs for unsupported timber span
sizes, give me an idea as to what size timbers I need for a floor? It
will be 3300mm between supports, spaced at 400mm, and will be used for a
shed / workshop (no particularly heavy equipment, just desk / chair /
electronics workbench etc).
Floor on top will be 18mm bitumenised OSB, with insulation between the
joists.
If I increase the spacing to 600mm, does that make much of a difference?
Thanks for the help
Gary
