Window Caulk - Brick to Aluminum

I'm going to have to recaulk some windows; brick exterior and aluminum framed windows.
Temperatures here go from 30 or so in the winter to 100 in the summer; sometimes lower than 30 in the winter...
Anybody have recommendations on caulk types? Silicone? Polymer? DuPont with Kevlar? It'd be nice if it'd stick to the brick...

I'd stick with a good exterior latex caulk.

Silicone is made to stay elastic with temperature extremes. Caulk not too much so and you have to keep it painted especially with an exterior application.

It isn't going to be painted; unless somebody else wants to paint all of the brick.

That looks interesting. And is totally paintable.

I have a policy at my house: Absolutely no silicone caulk allowed.

When it fails, and it will fail, its a bitch to clean out so you can recaulk. Nothing sticks to silicone so it absolutely has be 100% cleaned out.

Man, I hate that stuff with a passion!

I would use any of the terpolymer caulks on the market. Solar Seal is my favorite:

I use Ultima caulk by Geocell for anything important outside. Menards carries it, not sure where else you can buy it. That stuff sticks to anything, and the best part is it still looks good years later. I have some I used to caulk vinyl windows to pvc trim and the pvc trim to brick 6 years ago. It still looks practically brand new to this day.

Flex 9000, a thermoplastic caulk. Stays flexible like silicone, but it's much tougher and easier to work with.

Seconded. I started using it in about 2005 and it's held up very well. I probably have used more than a dozen tubes sealing brick to wood and wood to wood. Takes paint nicely. Wore gloves and used a "few" paper towels during application.

Don't be surprised if the neighborhood huffers get really friendly and offer to take out your trash!

It seems like the consensus is anything but silicone. I have some reading to do...

Also avoid acrylic, if you get severe temperatures variations it will crack/split.

Sonneborn's NP1 Polyurethane caulk would be at the top of my list. I usually buy it at my roofing supply store.

Thanks for all of the suggestions; I'll look at them all this weekend. Color may be a factor too; she-who-thinks-she-must-be-obeyed will chime in on that...

Due to the fact that you have two materials with widely different coefficients of expansion, you might need to use a bond breaker tape to insure that the caulk seal does not pull apart.
