I'm looking to install new floor joists in my loft between the existing ceiling joists.
There's a beam running the whole length on the loft over the top of all the ceiling joists. It's nailed to every ceiling joist.
The floor joists will be 175mm tall (mounted on 18mm ply) compared to the 100mm tall ceiling joists so I need to get them through this beam.
Does anyone know what the beam is doing structurally in the loft? It's not attached to the structural walls it crosses at all, only to the top of the joists and the rafters on either side of the the 12m span. It must have been part of the original 1930s house construction since it must have been installed before the roof.
I'm hesitant to notch it unless I can figure out what it's for.
Thanks in advance.
