On the 20'x30' 1.5, we are looking at different loft floor joist size options as we want an exposed timber look. We plan on a t&g wide plank floor on the loft. What sizes of beams are people using?
Also, I was looking for a span calculator for use with 4" wide timbers but have only found calculators for 2" wide lumber. Anyone know of a calculator for wider timbers?
On another project, I am wanting to use 4" wide timbers on a span of 12', what are my options here?
The loft floor plan for the 20' wide 1.5 story has an option for a beam and deck ceiling using Dbl 2x12 or 4x12 at 48" with 2x6 T&G on top.
Get a copy of Charlie Wing's "From the Ground Up" as it has good charts for sizing rough cut and dimensional sized timbers.
