With more and more building codes and installation guidelines requiring the use of sill pans during door & window installation you can be ahead of the curve by specifying the Jamsill Guard sill pan flashing for doors & windows.

The Jamsill Guard sill pan flashing has been providing protection against door & window leaks since 1983.  It is the only proven, time tested, easy to use, and economical sill pan flashing available.

The Jamsill Guard is manufactured from high-quality, high-impact ABS plastics. It is impervious to rust, corrosion, galvanic corrosion, electrolysis, and corrosive coastal areas.  It helps eliminate condensation from thermal transfer and does not require any adjustment to standard rough openings sizes.
