Hi all, I've done many a DIY home projects and I'm ready to finish my basement now. When I see pictures of framing and TV shows where the framing is exposed, frequently the ceilings have extra wood strapping running horizantally opposed to the direction of the upper joists.

I don't understand why they do this. Wouldn't it just be easier to attach the ceiling drywall directly to the floor joist on the floor above?

doug, That was the original reason for strapping, when hand hewn timbers or rough cut lumber was being covered over, but there are still more advatages to using it now.

It helps isolate sound transmissions form floor to floor

It adds a sandwich effect to the structure of the above floor, reducing vibrations more effectivly than solid blocking without interfering with spaces for mechanicals.

When trusses in cielings are at 24" oc, the strapping at 16" oc allows for use of 1/2" SR instead of 5/8" without sagging

It provides a wider surface for screws to find when fastening the rock up

Excellence is its own reward!
