Window seal to coach - Thin rubber seal
« on: April 07, 2025, 09:23:47 PM »
New to this forum and I have a 1995 Marquis.

I had a window that was broken from a weed-eater so I pulled out the frame and had the window replaced. It is a double window with one that slides open.  I need to reinstall and I see there is a thin rubber seal that needs to be replaced. It is about an 1/2 wide and does not appear to have any adhesive on it but maybe it had worn off. 

What am I looking for and what sources offer a replacement?

Thanks in advance for any help

Tony

Tony,

If  I understand what you are saying correctly, I think you are referring to butyl tape that goes between the window frame and the outer fiberglass wall of the MH.   You can buy rolls of butyl tape from amazon and just push it in place of the back side of the window frame.  Slide the window in and tighten the screws until it squeezes to tape out, and then clean off the excess tape. 

Hopefully this will be helpful.

Depending on the manufacturer and the build date of your coach there were several different types of seal used.
 The first which the window manufactures sometimes used was a closed cell double sided foam tape that was placed on the sealing flange of the window, these were expedient for installation but did not seal very well over time, the second was a putty tape which sealed better but with time dried out and would crack and leak .
The third as Carl has mentioned is butyle tape this is by far the best sealing method however with any of these sealing methods the seal between the flange and the wall is only the primary seal once the window is installed in place it is advised to use a clear caulking like lexol to seal the edge between the sealing flange and the wall after it's installed leaving the bottom edge open so any moisture that gets in can run out at the bottom.


Hope this helps

Thanks for the replies.

It seems to only have butyl tape when I took it out.  I now have a better idea of what to do
