Would this work well as a seal against cement foundation and metal window well? I want to seal where the metal well attaches to the cement.

GREAT STUFF(TM) Gaps & Cracks is an air sealant that is intended to seal gaps up to 1" wide. It can work well in this application, however if your gap is larger than 1", we would recommend upgrading to GREAT STUFF(TM) Big Gap Filler, which is intended for gaps up to 3". Additionally, please note that the GREAT STUFF(TM) Products are water resistant, but not waterproof, meaning they can absorb water and break down over time if frequently expose. Sunlight can also cause the foam to break down, so you may want to consider covering it with paint or a caulking material.
Should work well for insulation between cement/window as that what's it was intended for.
