Help - can i cut the wooden joist on top of an RSJ?

[Robert Cunningham]

Hi

I'm trying to fit a 4" extractor hose in a new bathroom but when I looked in the roofspace I can't get it between the joist and tiles/insulation.

The Joist is an RSJ with a large wooden batten bolted to it which the rafters are screwed into.

I reckon I could get the flexi hose through if I remove all or part of the wooden batten for 4 inches. I can't see why that would cause a strucutral problem but I wanted to check if its a bad idea

cheers

Rob

The pieces left either side of your cut may slide. Check that, or deal with that and your can do what you propose
