5.
Clean the back of the window module of the previous butyl seal using the methods described. Additionally, clean the top of the window module.
Pay particular attention to the lip of the glass that extends above the frame. This lip of glass (the side on top of the module) must be clean for the
gusset seal to adhere properly.
6.
Place short (25 mm/1 ") sections of standard butyl sealing cord behind the gaps between the side panes of glass and the division bars (Figure 4).
Make sure the butyl seats against the plastic frame at the bottom of the gap. If this is not done, the gaps provide a leak path for water to get by the
gusset seal.
