What is exposure plywood?
structure which is exposed to weather. Exposure 1-rated panels and sheathing can withstand exposures to inclement weather during construction, but are not suitable for extended exposure. The grade stamp on each panel will indicate whether you are using Exterior or Exposure 1.
What is exposure 2 plywood?
Exterior – Exposure 2 Interior type with intermediate glue. Intended for protected applications where only slight exposure to moisture is likely to occur.
Where should a plywood panel marked exposure 1 be used?
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.
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.
How long can CDX plywood be exposed?
That said, CDX plywood isn’t immune to the slings and arrows of Mother Nature indefinitely. Repeated or prolonged exposure to rain (or ice and snow) will eventually compromise the integrity of this material. The threshold for this is about four months.
What is the difference between CD and CDX plywood?
CDX sheathing is used primarily by contractors to build exterior walls and roofs. The letters “CD” represent the veneer grades used on the front and back, and “X” means the glue (not the wood) is rated for outdoor exposure—but only for a short time.
What does CDX plywood mean?
CDX plywood has one side veneer grade “C” and one side veneer grade “D”. The two are bonded together with glue which can withstand a little moisture. The APA would recognize CDX Grade Plywood as C-D Exposure 1 plywood.
Is RTD plywood waterproof?
Exposure 1 rated plywood, mostly called “CDX” in the trade. Exterior panels sometimes referred to as RTD sheathing, are designed to hold up to constant moisture. They are completely waterproof and are great for installing in places where you expect consistent exposure to moisture.
What is CCX plywood?
CCX plywood is unusual and difficult to find. Nevertheless, it is a standard grade of plywood, often made with pressure treated softwood. Just like BCX, CCX plywood comes in a wide variety of thicknesses, normally contains C-grade inner plies, and is bonded with exterior glue.
What is Plywood performance category?
Performance Category— A panel designation related to the panel thickness range that is linked to the nominal panel thickness designations used in the International Building Code (IBC) and the International Residential Code (IRC).
What is PRS Rs plywood?
Coastal produces Performance Rated Sheathing panels as defined in US Product Standard PS2-10 for Construction and Industrial Plywood. Coastal’s PRS panels are widely used throughout the industry in the construction of walls, roofs, and floors.
What is AC plywood?
AC plywood is made from thin sheets of wood pressed tightly together to create a durable and strong piece of plywood. One side of it is sanded and finished which makes it graded “A”. The other side of the board is not sanded or finished, so it is graded “C”.
What is plywood span rating?
Span Rating denotes the maximum recommended centre to centre spacing of supports in inches over which the panel should be placed with its strength axis across two or more supports. The further the supports are spaced, the thicker the panel needs to be.
What size is 48 24 plywood?
23/32″ – 48″ x 96″ – 48/24 Span Rating. Description: APA Rated Sheathing panels (Southern Yellow Pine Rated Sheathing, Southern Yellow Pine Rated Sheathing Panels / Softwood Plywood) are not manufactured with smoothness or appearance in mind, but offer strength suitable for most industrial applications.
