What is ps1 plywood?
PS 1-19 is the updated product standard covering the requirements for American plywood intended for structural (loadbearing) use. The standard details various grades of structural plywood such as sheathing for roofs, walls and floors, sanded grades and plywood used in concrete formwork.
What is the difference between ps1 and ps2 plywood?
PS 1, Structural Plywood, establishes requirements for structural plywood. PS 2, Performance Standard for Wood-Based Structural-Use Panels, establishes requirements for structural wood-based panels such as oriented strand board (OSB), waferboard and certain types of plywood.
Where should a plywood panel marked exposure 1?
Exposure 1 panels may be used for applications where construction delays may be expected prior to providing protection or where exposure to the outdoors is on the underside only.
Is structural plywood waterproof?
If you are looking for something that can withstand a lot of moisture, there is a special type of structural plywood called Marine Grade Plywood. This type of board is so adept at taking in water that it can even withstand hours of continuous boiling without de-laminating.
What is struc plywood?
Structural I, also referred to as “STRUC I,” may be OSB or plywood and is, essentially, a subcategory of APA Rated Sheathing. Specialized construction situations requiring installation of roof sheathing panels with the strength axis parallel to supporting structure also benefit from the use of Structural I Sheathing.
What is exp1 plywood?
Exposure Specifications Interior plywood, suitable only for protected, interior use, receives an exposure grade of INT. Exposure 1, or EXP 1, allows exterior exposure to the elements for a limited period of time during construction. Exposure 2, or EXP 2, also called IMG, allows less exposure to moisture or humidity.

What is Exposure 1 plywood mean?
Exposure 1 rated sheathings, either OSB or Plywood, have a fully waterproof bond and are designed for applications where construction delays may be expected prior to providing protection. Exposure 1 rated sheathings are made with the same exterior adhesives used in Exterior rated sheathings.
What is weather exposure 1 mean?
Exposure 1 panels are suitable for uses that are not permanently exposed to the weather, but where panels must resist effects of moisture due to construction delays or high humidity.
Can I use structural plywood outside?
They are not suitable for exterior use, because these adhesives will deteriorate when exposed to moisture and changes in temperature. On a more obvious basis, there are certain categories of plywood which are clearly structural plywood.
Is APA rated sheathing structural 1?
Structural 1 is a designation applied to APA Rated Sheathing where enhanced racking and cross-panel strength proper- ties are of maximum importance. Structural 1 panels are typically used in demanding applications such as structural shear walls and panelized roofs.
