Window sealer (rubber) loose

[murbot]

What's the best course of action to address the rubber seal coming out at a corner? Aside from the correct choice of completely replacing the rubber all the way around the window.

Is there something like silicone I can put in that space to seal it. We've seen no leakage on the inside...yet.

Sorry for the sideways pic.

Thanks

The way my window works is the rubber glazing holds the window glass in place but does not create a seal. The seal is on the inner edge of the frame where there is butyl tape between the glass and frame.
I think you can fix it with new glazing or non-sag dicor but it is more or less cosmetic.
Mine kept filling the area with water and growing moss. I added a stick on drip strip over the window and the problem went away.

The whitening of the rubber indicates the UV protection is breaking down and the rubber is stiffening and shrinking .

The glass is sealed ( glued ) to the frame on the inside , this rubber is to shed water from the outside of the glass over the frame to keep water and dirt from collecting in the frame lip .

Available in bulk lengths , put in hot water to make it more flexible prior to install .

I remove the rubber, wash the rubber and use a conditioner and clean the area that the rubber fit in to. Then put the rubber back in making sure that I get the corners in tight. Easy process and no sealer to mess with.

I see from your photo your window frames have proper drains for any water that does happen to make it past this rubber .
Two of the stationary windows on my coach did not have the drains ; water collected in the frame , and when the sun got to warming things up , the hot water destroyed the window seal and water got inside .

The seal ( butyl) was so compromised that the glass was floating around in the frame with only the rubber holding it in place . A member with a coach similar to mine had the entry door glass blow out at highway speed probably due to the same situation .
So it's very important to keep dirt or sealant out of the frame trough and drains so any water gets out of the frame .
