(A) simply butting end-grain to end-grain is *not* a good idea. at a
minimum, consider using a lap joint, like this:

(B) Any good wood glue will be fine. I don't see any 'need' for the
price premium for Gorilla Glue.

There _might_ be a need for a "stretchy" glue -- say the type you use
for lamination if there is a lot of expansion and contraction cycles in
that window. (Hot sunny days, cool nights etc.) And Gorilla Glue is that
stretchy type for laminations. Other than that... And of course some
glues are more heat resistant than others.


With both pieces made of the same species, and the grain running the
_same_ direction, both pieces will move identically. Whereupon glue
'stretchiness' becomes a non-issue.
