Webster defines a raincoat as 'a waterproof or water-resistant coat.' Pretty self-explanatory.

So, naturally, a rain jacket for your home is designed to do the same thing - protect your house from both water and air infiltration. Because, let's face it, you can replace your home's windows with the best product on the market, but if they are not installed properly, you could end up with a bigger problem than when you started.

The Rain Jacket Flashing System is a revolutionary new replacement window flashing installation technique that utilizes specific components to pre-flash the existing opening without removing the existing cladding/siding when installing replacement windows. This patented replacement flashing installation has been tested at an AAMA (American Architectural Manufacturers Association) certified lab and field tested with many different cladding systems.

It has surpassed all testing guidelines with its ability to resist water and air penetration. With the advent of new building codes, the Rain Jacket Flashing System meets all requirements of new code without removing existing cladding. This includes sill pans, jamb flashings, head flashings, membranes, and integration to the building envelope, as well as drainage over the cladding if necessary.

So how do you know when to use the Rain Jacket Flashing System? We're glad you asked!

    Among the many benefits this system has, a few are:

    • Does not rely on an exterior caulking bead to prohibit water and air penetration

    • A true air and watertight replacement window flashing installation will maximize the efficiency of your new replacement windows


For years, single family homeowners have been under served and under protected from potentially destructive replacement window installation methods that have dominated the market. Through testing and constant innovation, the Rain Jacket Flashing System has established a patented combination of techniques and materials which help protect your home's structure from destructive water penetration and the issues it creates, from rotting walls to invasive molds.
