Big thing with waranty is plumb and square. Takes some attention, but

The other thing is exterior moisture barrier / flashing. Not installed

That's what spray foam is for ;}


Spray foam is for rookies. Put the window in right!

EVERY pro installer uses spray foam - to install it right.(the spray
foam isn't the be-all and end-all, but is virtually "required" for a
tight installation.) Use the "low expanding foam" only, or it will
warp the window very badly.

I was half-way joking. The "pro" installer might also use closed
cell backer rod and stuff the window/door jamb cavity with it.

I don't know the R-Value of backer rod vs. spray foam.
