Re: Sealing around heating vents
If I understand this is for forced air heating vents?
There shouldn't be a need for high temperature materials used for the sealing the gaps .... otherwise the vents wouldn't simply be attached to the wood structure.
The temperature is likely going to be around 100 degrees F which is not considered high temperature.
As far as off gasing I don't think there should be an issue unless there's a flame present allowing the material to burn.
Here's an example of one brand and where they recommend to be used......
However .... if you have any concerns you could always contact the company for whichever product and find out directly .
