What Is a Jamsill Guard™?

Jamsill Guard™ is a molded ABS plastic weather proofing sill pan flashing. Jamsill Guard™ should be installed in the rough opening before the door is installed, especially in extremely exposed areas.

Our seven series are designed to fit most steel, smooth fiberglass and textured fiberglass door applications. They can be used with either 2 x 4 or 2 x 6 construction.

The unique seemless molded corners completely wrap the subfloor and plate. The interior edge creates a continuous seal along the sill edge.

Jamsill Guard™ is not visible after the door is installed.
