Web Joist as lintel?

[gravelrash]

I have a 4.6m opening in new build with non loadbearing timber 1m high wall above. SE specified 2  9 x2 timbers as lintel with timber frame above...I was wondering if using a web joist as lintel would be just as good and easier.  Any thoughts?

[Nickfromwales]

If 2 9x2’s have been specified then I’d assume the SE has detailed for them to be mechanically connected to one another along the centre point. 
Pozi’s won’t allow for that type of connection, so I’d say glulam or joists for this purpose but not Pozi / I joist etc.

+1 fir glulam but not I joists.

As above glutamate is good, web joists need stabilising laterally and torsionally. A lintel needs to be stable in its own right.

should have explained in more depth- the web joist would entail 2 joists, 1 on sat on each cavity wall with osb on sides, top and bottom, so a structural box which can be filled with eps bead

The osb will do a lot to stiffen this up but your SE would need to sign it off.

Amino acid according to Google.  I had only heard of it as in monosodium.
