Sole and Header Plate in I Joist Construction

[davidc]

Planned construction is 1.5 storey with 350mm I Joists at 600mm centers with blown insulation. Are there any likely reasons why also using I Joists (rather than glulams) for the sole and header plates might be a bad idea ?

Given a proper - that is to say competent and professional design - then price is the factor that would concern me most.

I had a 350mm I-beam frame built which used I-beams for the sole plate. There aren't any header plates because mine is a portal I-beam frame but I have seen I-beam wall plates used.

Thanks, both.

 

'Also' because the vertical elements are already specified as I beams but not the horizontal elements. Perhaps I didn't understand your questioning the use 'also' ?

 

On the price concern, wouldn't i beams (rather than glulams) for header, sole plates be less costly anyway ?

the only consideration would be the need for insulation in the web under the soleplate to avoid cold bridging
