Step 5:
Stick lengths of
impregnated slow
expansion foam tape to
the two jambs and
across the head of the
window.
Extend the Acrylic
impregnated slow
expansion foam tape on
the head about  1 inch
longer to accommodate
shrinkage.
Fold down the overlap
to prepare for inserting
the window.
Step 6:
Insert the window 
into the opening taking
care  to be sure 
the impregnated slow
expansion foam tape is
not disrupted.
Use a  flat blade putty
knife to adjust foam tape
to avoid any disruption.
Using a screwdriver, lift
up the overlapped foam
tape on the header to
allow proper seating 
of the joint during
expansion.
