Installing replacement IGU

Hi.

I am replacing the thermal glass in a large picture window, and the original window is set in with caulk. What is the proper sealant to use? I was going to go with regular 100% silicone.

Tia,

Jeff

Two-faced tape is often good to use. On some windows the perimeter can be neatly wet glazed after the glass is installed and the tape is removed.

Generally setting a window into silicone will make a big mess when it squishes out. But yes, you always want to use 100% silicone on glass. And not all silicone is equal in quality or adhesion. Dow 795 is one that commercial Glaziers often use. Your 2/$5 silicone is of poor quality.

Thanks for the quick reply.

The guy in the video I watched used caulk and made it look easy, but I like the idea of glazing tape. I will check it out.

Thanks again.

If you plan to use glazing tape, remember that the surface should be perfectly clean. Remove all caulking and clean with mineral spirits.
