Sealing traditional glazed ‘windows’ in rebated wooden cabin.

[Nigelb]

I have traditional 4mm toughened glass windows that sit in a wood rebate that is varnished. The external surface is flush with the cabin and secured with a chrome frame screwed int the cabin side. so I am looking for a flexible sealant that is UV resistant but bonds to glass and varnish. I have approached Sica. Technical but they forwarded their marine guide that only appeared to cover modern systems.

Can anyone advise on the proper sealant to use in this traditional setup please?

Butyl in tape form as used widely in the glazing industry.

This is what I have used in the same circumstances as the OP. It stays flexible and never goes "off" so it continues to stick to the glass and doesn't "peel". I find that it beats Sika et al hands down. I use brown as it tends to blend in on timber better.

I asked about the same question last year, see this thread:
Alternatives to silicone – butyl...or something else?
Ended up using a combo of butyl on cartridge (for the void between glass and wood) and very thin butyl tape (under the frames).
Hasn't leaked a drop.

Many thanks this is the way to go.
