Attic storage

[WWilts]

Attic height too low for habitable room, but interested in having storage space there without overburdening roof truss beams.

Any suggestions?

I have done just that in our warm loft, used I beams fir rafters with 400mm insulation between, osb clad inside and sealed, foldable loft ladder into large loft with floor.

Thanks.

Did the roof truss supplier include the I Beam as part of the truss, or did you add I Beams between the roof trusses?

May be cheaper to ask the truss designer to include a loading in the truss design. You could then use loft legs:

Interesting, I was hoping PIR sheets between the ceiling and attic floor boards would equal 250mm of regular loft insulation but was worried this could be a moisture trap and be a concern with insulated wires.

 

Am I picturing the I beans correctly, do they sit inline and on top of the truss joists or are they laid across the truss direction?

Depends if you want a warm loft or cold loft. Mine is warm (insulation under slates), My whole roof structure is made of I beams instead of rafters, the depth, 400mm, gives me 400mm for rockwall insulation.
