Rated Sidings:
Designate thickness, APA trademarks, face grade (for APA RATED SIDING-303), Span Rating,
texture, pattern, dimensions, number of pieces. For example:
- 19/32" APA RATED SIDING 30318-W, 16 oc,
rough-sawn Texture 1-11, grooves 4" o.c., 48" x 96", 100 pcs. (Note
manufacturer's tradename if desired.)
Concrete Form: Designate
thickness, APA trademark,Class, dimensions, number of pieces. For example:
- 5/8" APA PLYFORM Class I, 48"x
96", 100 pcs.(Plyform panels are manufactured only as Exterior panels and are
mill-oiled unless otherwise specified.)
Overlaid Panels: Designate
thickness, APA trademark, grade, Group number, dimensions, number of pieces.
For example:
- 1/2" APA MEDIUM DENSITY OVERLAY (MDO)
or (APA RATED SIDING 303-OL in the case of overlaid panels produced under the APA RATED
SIDING-303 manufactur8ing specification), Group 1, 48" x 96", 100 pcs. (Any
special requirements, such as only one side overlaid, surface texture or weight of
surfacing material, should be stated after the standard specifications.)
Grade Availability
Some panel grades, thicknesses, Span Ratings, or species
may be difficult to obtain in some areas. Check with you supplier for availability or
include an alternate panel in specifications. Standard panel dimensions are four feet by
eight feet, although some mills also produce panels nine or ten feet or longer.
