FAQ
Drywall Ceiling Calculator questions
Should ceiling drywall run perpendicular to framing?+
Layout depends on framing direction, sheet length and the approved assembly. Plan joints before ordering.
Does this include joint compound and tape?+
No. Use the joint-compound calculator for finishing materials.
Why can ceiling screw spacing differ from walls?+
Ceiling panels resist gravity and must follow the fastening schedule for the selected board and framing.
