RE: New home noises - need some advice?

Dennis:

You are not going to get screw pull through as you asked earlier in
partitions, the loads required would be too high (assuming the screws were
screwed in in the first place.  I would look at waterlines not isolated
(sprinklers, icemakers, toilets that go on and off automatically causing the
lines to move.)  Also hvac ducts in the walls and flat water heater or fau
vents.  These ducts and vents could be making the noses themselves with
thermal changes (like one of the ac vents in our home) or they could be
bumping the studs.  If the noses are when there is a wind or temp. swing, it
may be the NON-bearing trusses rubbing on the top track.  As the home is
occupied, I doubt that the thermal swings within the partitions  will be
sufficient to cause movement in themselves.  These are the thing that I
could think of as they may relate to the steel partitions.

Good luck

George.

George,
The roof trusses were plated wood trusses - the energy calculations will not
work for most homes out here in the desert that use steel roof trusses. This
is why it is much more common to find metal stud homes with wood truss
roofs, or in this case wood stud exterior walls, steel stud interior and
wood truss roofs.

Thanks
Dennis
