Here is a sample wall being sprayed. It is really interesting how it does indeed fill all the nooks and cracks. We have sealed all the seams with caulk so we should be pretty ready for a blower test once the insulation is done.
All the high spots have been sprayed and look good. Since the foam is non combustible it can be applied directly to the metal flues. All the holes should be sealed up.
Filling out the spaces between trusses is a simpler task. Non the less it is time consuming.
The ends of the trusses have cardboard baffles to restrain the foam from going into the eaves. The process is quite painstaking since it requires being close enough to aim the nozzle in the right place but not too close since the pressurize liquid needs some distance to be applied right.
