Question
hi diane,
are 4x2 joists over a 16ft stretch strong enough floor support for my sons bedroom ,i have added noggins every 400mm along the beams but am still unsure if this will be strong once i floor board it [the joist are 330mm apart] thanks.
Hi, Paul.
2x4's are NOT strong enough to span that distance, even at 13" on center (330mm). You really need input from a licensed contractor or a structural engineer, to size the joists for the span and the intended use, i.e., dead load and live load. They can also advise about the appropriate joist hangers that should be used.
Good luck with the loft conversion, Paul.
