I am installing some thermopane style glass to replace 25 year-old
thermopane glass that had lost itsr seals and become cloudy. The
glass company where I had the windows fabricated gave me a caulking
size tube of Industrial/Construction RTV Silicone - "professional
Quality" manfactured by c.r.laurence to use when mounting the glass
in the window frames. I'm trying to figure out how this silicone
rubber differs from the "standard" silicone rubber sold at hardware
and big box stores.

Helpful comments appreciated.

There's a boatload of different "silicone" formulations. For example,
many of them are great sealers, but lousy adhesives. Likely every brand
has a dozen different formulas for different applications. I'd pay
attention to that aspect.
