Ask your local supplier if his foundation wood is AWPA
approved foundation wood.
You are bound to get a response like UC4 What? Or sorry
we only speak English (and
maybe Spanish) around here.
Maybe something like
OH, IT'S TREATED UNTIL REFUSAL. That's
short for the wood is so hard
it won't take the level of treatment required.
SURE WE'VE GOT GROUND CONTACT TREATMENT. Which may,
or may not be, suitable for skirt board, but is not appropriate
Fence posts rot due to fungi and boring insects. They aren't required to support
huge loads for extended periods
of time like foundation posts or laminated columns do.
So it makes sense not to buy posts treated like a fence post right?
Most lumber companies stock 6x6 and larger posts that
are treated UC4A (or poorer) and often treated with inferior
types of chemicals and
Demand the right product, the price goes up, and it's a special order.
What About Hardware?
Some treatment chemicals are more corrosive than others when placed in
contact with hardware.
Matching hardware and treatment type is an important part of
wood and the hardware used with it.
Proper Sizing of Members
Many factors influence the size and spacing of foundation
posts, or if posts should even be used
(manufactured laminated columns are stronger, straighter, better!). Site specific
issues like 3 second wind gust and snow loads and
building specific factors like wall height, truss span,
floor joists or attic trusses for second floor use, and open walls are
all critically important to properly engineer a building with the right size post.
DIY BUILDER? Ours Are Longer
We provide foundation posts and laminated columns that are 1'
to 2' longer than required
to make embedment and truss placement a snap. Get
everything square, lined up, place the trusses
the right height, then cut off the top of the post in line
with the top chord of the truss.
We get calls from people that purchased exact length
posts (elsewhere!), set them, and then realize that their anticipated
wall height isn't what they end up with...exact length posts are harder to
work with, and can prove inconvenient!
Ours Are Even Longer
Our gable posts are full height. Many suppliers provide
gable posts the same length as the eave side posts.
Full height gable posts
extend to the top chord of the
truss providing two benefits.
• First, temporary bracing
is minimized when placing trusses since the post provides support
instead of elaborate temporary bracing.
• Second, the full height
post provides substantial strength and stability for the life
of your structure. Many
budget packages do not include full height gable posts.
Buy from us and make sure your building has an engineered foundation with the right treatment level to last a lifetime.
