The Jamsill Guard® is 1/8" thick. Typically you won't need to adjust your RO tolerances to accommodate our sillpan. But if you are concerned with fit, an 1/8" to 1/4" would be fine.
No. Once the door or window is installed, the Jamsill Guard® is locked into place. Caulking can be used under the pan to prevent air/pest infiltration.
For swinging doors and wood windows measure the jamb width. For sliding doors and vinyl windows measure from the nail fin back to the interior edge of the door/window frame. If you are installing an out-swing door make sure the jamb dimension is the same as the wall thickness. Sometimes a 4 9/16" jamb out-swing door is used in a 6 9/16" wall.
At least 1 1/2" overlap at each joint is required for proper bonding.
ABS or PVC Cement is the only bonding agent that can be used. **Do Not Use All Purpose Cement or Caulking**
Typically it will take approximately 5 minutes to bond the pieces together using regular PVC cement. However bonding times vary depending on temperature and humidity. The higher the humidity and/or the colder the temperature the longer it will take to bond.
Measure how much material needs to be trimmed off the center piece, and use a hacksaw or a pair of tin snips to cut. Be sure the center piece fits within the recessed glue tab areas and that you maintain the required overlap.
We can custom cut our sill pans to fit any size rough opening. Just tell us the rough opening dimension when ordering, or order the next larger size and trim down the center section.
