sill Plates
Check your bottom plates to see if they are all
the same dimension in width. Install all of the
sill plates level ( ± 1/8”), square (within a 1/4”
of being square on the longest diagonal), and to
the exact dimensions of the layouts on the shop
drawings. When placement of the wall panels
is directly on top of a concrete foundation,
remember that because the panel skins cannot
bear directly on the concrete, a capillary break
and solid bearing is required.
One of the best methods to provide a capillary
break is to use a treated sill plate that is either
equal to the total thickness of the panel or
slightly wider.
Take your time and do a good job when you lay
out the sill plates. Time spent now will save
you time throughout the rest of your project.
When you lay out the sill plates, always use
the longest building line to establish the base
line. Use this base line to establish the largest
perpendicular building line available and make
it square to the base line. Be exact. Use a
calculator or the largest ratio of a 3-4-5 triangle
to do this. Measure parallel to either of these
reference lines for all other smaller dimensions
that are within the structure. Adjust or shift sill
plates as required on the foundation system to
match all the desired dimensions on the panel
layout drawings.
Snap a chalk line on the foundation wall for the
inside of the sill plate and begin setting your
plates. Use an appropriate sill sealer under the
sill plates. Level the plates as required.
