QUESTION About Replacing Windows

[DMacLeod]

I have a 2021 Grand Design Momentum 397TH and I'll be replacing one of my windows. Does anyone know what type of tape/sealer Grand Design uses when installing windows? I believe there are two different types, Butyl or Foam, and I'll like to use the same as when the windows were installed.

I have seen most with the foam "tape". If I was doing it I would use the butyl tape, it seems to make a better seal.

Lippert has a lot of information on windows. (They are the OEM supplier to GD.) There's even a course available online ( pic of course below where you can take once signed up at https://lippert.learnupon.com/users/sign_in ).

I replaced one on my 2800. It was foam tape. GD will sell it to you. Silicone around the top and sides after install.
