CertainTeed 1/2-in x 4-ft x 12-ft Easi-Lite Regular Drywall Panel

Twelve-foot lightweight stock cuts horizontal joints on long elevations but demands serious staging: protect long edges and plan lifts before the boom truck leaves.

Do it Best lists model 639967 / UPC 00800805145506 for a 1/2 in. x 4 ft x 12 ft Easi-Lite panel; Lowe’s search indexes item 1002998870 for the same module in public results—reconcile on your PO.

ICC-ES ESR-3692 remains the ceiling-span reference for Easi-Lite; do not exceed evaluation limits for insulation weight and orientation.

Feature-to-benefit translation: the “lightweight” feature buys reduced crew strain and faster vertical stocking on mid-rise carts; the “sag-resistant core” feature buys ceiling confidence when the evaluation report’s assumptions match your insulation and framing plan—verify both.

Commercial intent: buyers searching “12 ft lightweight drywall for tall walls” need clarity that module length does not remove the need for control joints per engineer on expansive ceilings; follow GA-234 and project details for large uninterrupted planes.

Fire and STC: Easi-Lite is not synonymous with Type X; when a lease spec says “1/2 in. Type X,” this SKU is the wrong family unless the drawing explicitly allows a lightweight 1/2 in. line in that assembly (rare).

Delivery QA: long sheets telegraph minor edge damage under raking light after paint—reject crumbled corners before hangers lift, and photograph bundles if trucking claims arise.

Sustainability narrative: pair GREENGUARD Gold positioning with jobsite waste sorting; recycled-content papers help LEED documentation only when your certifier accepts the current manufacturer letter.

Voice/conversational queries: “Is 12 foot Easi-Lite good for ceilings with blown insulation?”—answer by opening ICC-ES ESR-3692 for load and orientation limits rather than guessing from marketing blurbs.
