Basic information about biomass: raw materials and processes for biomass energy generation, energy content of various biomass resources, and uses for biomass energy. The term biomass refers to raw organic material used to generate a number of energy resources, including heat, liquid or gaseous fuels, and electricity. Chemical energy stored in biomass can be converted to heat through combustion (burning). Biomass can be converted to liquid or gaseous fuels or can be used to generate electricity in the same way that coal is used. The electricity generated can be sent to energy consumers via electric transmission systems.
Steps. 1  1. Nail top plates to all the outside walls. 2  2. Measure and cut ceiling joists from 2-by-4 lumber. 3  3. Cut a ridge board form 2-by-6 lumber.  4. Lay planks across the ceiling 1  joists. 5. Calculate the rise of the gable roof.  6. Measure and cut the rafter boards from 2-by-4 1  lumber. 7. Make a collar tie for each pair of rafters.
That is, with the ladder fastened directly to the first truss and not over top of the gable end wall and then fastened to the first truss inside the gable end as is the norm. I was thinking between 6 and 8. RE: ladder truss cantilever length. In this case the roof sheathing is actually acting as the cantilever, the type of roof sheathing would determine the maximum overhang. Fascia would be attached directly to the roof sheathing and ladder framing is not needed. Check local building codes to see if this allowed in your area.
