Difference Between Window Glazing Putty and Caulk

Multiplicity of usage

I would advise that for everything window sealing, use a window glazing putty, and for every other sealing asides windows, use caulk for such purposes.

Caulk and window glazing putty is different as they function for various purposes.

However, caulk is the best to use in every other application that doesn’t involve windows whilst the putty can come in handy for all window applications.
