    Before I clip on the interior pvc trims, I want to fill the joins between the windows for maximum sound insulation.

    What would you say is best?
    • Silicone
    • Caulk
    • Expanding foam
    • Something else

    What I am referring to:

    Foam. Anything solid like caulk or mastic will just transfer sound.
    Abrickie and WillyEckerslike like this.
  3. They should have been made properly, without the need for any bodger bead to cover that up.
    I would complain and get them to make the window correctly.
