Sticking Details

Sticking is the detail in the wood that surounds the glass in a window. It helps direct moisture away from the glass while providing a decorative appearance. Below are our standard patterns. Notice that two patterns allow for true divided lites (TDL) and one of our patterns allows simulated divided lites (SDL). Ask about advantages of each for your individual situation.

Thermal lead

Our thermal leading is custom made to order. The drawing below shows a piece of insulated glass cut in half. The lead is applied to both sides of one of the panes of glass so it can be seen from both sides. We leave the lead off of the other side of the glass to allow for a low-e coating for maximum energy efficiency.
