Insulated glass in front doors

摘要

In a sidebar in Josh Finn's article "Build Your Own Front Door," FWW #226, there is a recommendation to bed insulated glass in clear silicone. My company builds custom doors, and our glass suppliers have warned against this practice because it can damage the rubber sealant used in insulated glass fabrication, possibly allowing fogging. So we use Infinity urethane caulk to bed door glass. It works great and has the extra advantage of accepting paint and varnish.
