UV-Resistant Glass Sealants
These sealants don't degrade in sunlight. Also known as glazing compounds, use these sealants to install glass in framing. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, these sealants are RTV (room-temperature vulcanizing).
Elongation and joint compression/expansion tolerance indicate flexibility. For joints between dissimilar materials and in environments with wide temperature fluctuation, choose a sealant with a higher elongation or joint compression/expansion tolerance.

Glass Sealants
Also known as glazing compounds, use these sealants to install glass in aluminum, steel, and wood framing. They’re non-sagging, so they won't drip from vertical and overhead surfaces. These sealants are good for use between dissimilar materials and in environments with wide temperature fluctuation. They must be painted after hardening to stand up to UV light. For sealants that require primer for use on wood, use any oil-based wood primer.
