How's this for service?

It Pays to Know Your OSB Grade Stamp

To be sure you are getting the proper panel for the job, ensure you
refer to the grade stamp on the panel. The stamp contains important
information including specifications and code requirements that will
assist you in selecting the right panel.

Certification Agency
The top of the stamp will bear the name of the agency certifying
panels to performance standards recognized by all major North
American building codes—the National Building Code (BOCA), the
One and Two Family Dwelling Code (CABO), the Standard
Building Code (SBCCI), the Uniform Building Code (ICBO), the
International Building Code (ICC) and the National Building Code
of Canada (NRCC). These codes recognize OSB for various
applications, including single layer floors, roof sheathing, siding,
soffits, subfloors, underlayment and wall sheathing. Panels are
certified by three nationally accredited agencies: TECO, APA and
PSI.

Standards
Below the name of the certification agency will be the name of the
standard, for example PS 2. OSB panels are manufactured to meet
performance criteria set by the U.S. Department of Commerce's PS 2
Performance Standard for Wood-Based Structural-Use Panels. In
Canada, panels must comply with the Canadian Standards
Association's CSA O325 Construction Sheathing or CSA O437 OSB
and Waferboard. All three standards set maximum values for
deflection under load, dimensional stability, and minimum values for
strength, stiffness and lateral nail loads.

Structural Grades and Dimensions
One of three grades - Sheathing, Structural 1 Sheathing, and Single
Floor - will be stamped. Sheathing is for use in construction
applications, such as covering material for roofs, subfloors and
walls. Structural 1 Sheathing is a sheathing panel that meets
additional requirements for cross-panel strength and stiffness. Single
Floor is for use as a combination subfloor and underlayment. Next to
the grade will be numbers for panel thickness and span rating,
indicating allowance for roof and floor spacing respectively.

Bond Durability Classification
One of two exposure categories – Exterior or Exposure 1 -
determines where panels can be used. Exterior panels, fully
waterproof, are designed for permanent exposure to the weather.
Most OSB panels are classified as Exposure 1, suitable for panels
that are not permanently exposed to the weather that must resist
effects of high humidity and moisture during construction delays.
To order OSB panels, the specifier or builder should designate
thickness, trademark grade, span rating, bond durability
classification, dimensions, "square edge" or "tongue-and-groove" as
desired for thicker panels and number of pieces. One glance at the
certification stamp will confirm key requirements.

ok so i have read the litturchur

now, if it can be said creativly. are the other places selling lesser quality for the low dollar, in reguards to a higher priced establishment in your opinion?
 
I am going to try to get my thoughts across on this Larry.

I often am contracted to do the labor only on a building, the customer has shopped around got the cheapest deal on their package and just wants a licensed builder to do the work...no problem. OSB is 4'x8' all day long, any of it will work.

When I am contracted to also purchase the materials I go to my local mom and pop lumber yard who happen to sell " a very good name brand" I prefer to use the "name brand" they sell because I find that it will hold up better during the construction process. Example: The "name brand" stuff on a floor seems to handle the abuse of all the subs walking on it, drywallers spilling water on it, the typical wear and tear involved during the job. When I have used the "cheaper" stuff at the BORG, I find it will flake easier and not stand up to the traffic involved in building a home as well as the "name brand" If my name is going to be on the job as the general contractor...I want the good stuff, if I am hired as the framer...then the homeowner has to look at themselves for any problems in the quality of material.

Will the cheap stuff work for the average do it yourselfer working on his own project? Yeah, it works for the pro too, but it in my opinion and use in the field for 18 years find that the better "name brand" stuff will hold up better. It seems the glue, fibers, chips all hold together better in the long run.

....as always....your mileage may vary.
 
I bow to Steve's vast experience in this area (as my own experience is limited to the occasional "project" as far as OSB is concerned).:bow:

Larry - Sorry if I misunderstood your original question, but I hope the information provided was helpful none-the-less.

As for the name brand stuff, well, of course I think ours is right up there ;) . But.... you really can't go wrong going with any of the 'big boys' in this field.

Last but not least, here's a spelling helper - just remember the vowels in Weyerhaeuser are in order (remember AEIOU?).:D :rofl:
 
Good spelling advice Rennie, I'll remember to double check that the next time I place an order at my local Mom and Pop lumber yard.
