CertainTeed 1/2-in x 4-ft x 8-ft Regular Drywall Panel

Stock four-by-eight modules dominate residential takeoffs because they balance seam count, doorway logistics, and crew muscle memory.

CertainTeed publishes Regular gypsum board for standard interior walls and ceilings with GREENGUARD Gold certification and ASTM C1396 compliance; Castle Building Centres lists model 640262 / UPC 772677002358 for a 1/2 in. x 4 ft x 8 ft regular board in North American distribution examples.

Treat commodity gypsum as part of a system: continuous air barriers, penetration firestopping, and rated assemblies still require the exact board type named in the UL/GA design—not an assumed Regular sheet.

Field QC means dry storage, carrying panels on edge, and following GA-216 / ASTM C840 fastening schedules for non-rated work unless engineering specifies otherwise.

Buyer intent mapping: shoppers comparing “CertainTeed vs USG vs Georgia-Pacific” are often deciding on paper quality, edge hardness, and distributor availability—not mythical “stronger chalk lines.” Anchor decisions on submittals: recycled-content statements, surface-burning language in ASTM E84/CAN-ULC-S102 family testing cited by the manufacturer, and the precise board name on the UL listing.

Long-tail jobs where Regular fits: remodels patching into existing tapered-edge stock, basement rec rooms where no enhanced mold board is specified, and commercial TI when the finish schedule calls for standard interior gypsum before a Level 5 skim.

Problem–solution framing: the pain point is schedule risk from damaged long edges and callbacks from the wrong board in a rated chase; the fix is verified deliveries, edge inspection at offload, and disciplined substitution controls tied to the architect’s GA-600 references.

Moisture reality check: Regular gypsum is not marketed as a wet-area board. Laundry rooms, tub surrounds, and any continuous high-humidity venue typically need moisture- or mold-resistant panels (for example CertainTeed M2Tech) when the spec says so—do not rely on paint alone.

Acoustic and energy notes: a single 1/2 in. finish layer is a modest resistor (often modeled near R-0.45 in residential stacks); STC gains come from assembly design—double studs, insulation, seals—not from swapping brands of the same thickness class without engineering.
