Installing foam deck on top of existing teak

[Muaddib1116]

A company in RI has told me that they can install foam deck material on top of my existing teak decks. The benefits are that it would cost a tiny fraction of replacing the teak with something like cork, it would provide a cooler deck surface and add a bit of insulation, and they claim that if I want to in the future it can be removed without damaging the teak. The teak would probably need to be sanded at that point, but in the time that it is covered, the foam deck would be protecting the teak, preventing wear and aging.

This sounds like a very appealing option, but I can't find anything like this online. Has anyone heard of doing this? Is this a terrible idea? Thoughts?

Like everything with decks.... if it’s done right.

You will need to treat every deck fitting as if you had a balsa cored deck.

Hope they’re really good.

Trapped moisture under the foam in the teak can’t result in a good long term outcome. IMHO It’s literally a rotten idea. I’d find an installer who has better judgment.
If this guy would recommend such a big mistake, what smaller misjudgments will be made during the installation?
