Strapping The Ceiling

Strapping the ceiling can not only make drywall placement easier, it can actually strengthen the floor above.

can I use 2x4's for strapping

Hello Jim,
Sure - but why spend the money and loose the headroom?

Hello Doug,

According to the CGC handbook - when drywall is placed parallel to the strapping, the strapping must be on 16" centres, when placed perpendicular to the strapping it can go to 24" centres -- but this is not recommended if water based texturing material (like stucco) is to be applied. 

When applying texturing materials, it is a good idea to use Sag Resitant drywall panels.

1-1/4" penetration into the wood -- hence with 3/4" strapping, a minimum of 2" long screws.  If you are using very dry 1x3s for the strapping it would be wise to pre-drill through the strapping to avoid splitting.

How far apart can ceiling joists be to support 1/2 drywall without sagging?
