Worth it for insulated electrical boxes on external walls.
This foam did an amazing job at keeping away air drafts on external walls at my electrical outlets and light switches.

Fills up the space
I mistakenly bought the orange color of Great Stuff. It still works and the area I needed it does not show too much. I like this stuff, but it can be a little messy if you are not careful.

A Needed Prevention
I am having some drywalling done and adding electrical outlets to a partially finished basement. So, I purchased and used Great Stuff 99112831 Smart Dispenser Fireblock, Orange for that added measure for fire safety. It was easy to dispense in the needed areas and hopefully is an added precaution used for those just in case emergencies due to an electrical fire. This foam was used around all electrical areas as a barrier to prevent the spread of fire and smoke allowing my family ample time to leave the home safely. Other like firestopping materials were used as well.

Work Great in Sealing Plumbing and Pipe Penetrations
Heading says it all. This Fireblock expands quite a bit, so don't think it won't seal larger penetration holes where someone was careless in creating an opening that's way bigger than is required. It expands slowly at first, but you'll see how much it expands after about 20 ~ 25 minutes. Test one opening first to avoid having to trim a large amount of excess and waste product. Will definitely use this product as needs arise!
