How is the glass set in the shoe molding?
The following wet glaze method is historically the most common in setting glass in base shoe molding. It requires a “wet” filler of either quick setting expansion cement or silicone. The PanelGrip system provides a dry mount option that will reduce glass setting labor costs by 75%.
In a wet mount system, the general procedure for setting the glass is as follows:
1. Place setting blocks into the shoe to center the glass, provide support, and prevent glass-to-metal contact. The setting block does not need to run continuously and should be placed 1/4 the width of the lite of glass from each end. Spraying glass cleaner on the setting blocks can make later glass placement easier.
2. Set the glass into the setting blocks. Use shims to position the glass vertically plumb. Align your glass for its final position.
3. Affix the glass into the shoe molding using a filler. As mentioned earlier, the choice of filler may vary depending on the installer and specifications. Some installers will use a silicone or expansion cement. Some will use a combination of the two. By far, the most common filler used are quick-setting expansion cements such as Rockite. Do not use epoxy-based fillers. Warning: Do not use Portland based cements as filler with laminated glass.
4. Insert a backing rod and top with silicone for exterior applications to prevent water accumulation. Otherwise, use our gasket along the top.
