Rain Jacket Flashing System

Did you know that most window installations are not done properly? According to the director of the American Architectural Manufacturers Association (AAMA), nearly 8 out of 10 replacement windows are installed incorrectly! Common problems include the use of low-grade sealant without nail fins and a lack of integration into the existing building paper—leaving windows vulnerable to water damage, air penetration, mold, and rot.

Instead of taking a gamble on the installation skill of local window companies, turn to the proven experts at 2FL Windows & Siding! We’ve eliminated the common problems of shoddy window installations by inventing and patenting our own method, the Rain Jacket Flashing System. By using this revolutionary installation system, we guarantee windows that live up to our motto: Integrated-Leakless-Flawless!

Shield Your Seattle and Tacoma Replacement Windows With a Protective Rain Jacket

During our more than 25 years of industry experience, we’ve seen nearly every kind of window installation method: glue and screw, nail on, cut out, and stucco fin. Though these methods are quick, easy, and popular, they often result in serious long-term problems, including:

  • Compromised weather barriers from torn or broken building paper
  • Vulnerable spots in exterior caulking, which may crack or peel
  • Smaller windows (due to the need to fit into the existing frame)
  • New entry points for water along exterior fins

To prevent these costly issues, we invented the Rain Jacket Flashing System, an installation method that utilizes multiple layers of flashings, back pans, and high-grade membranes. This system takes more time and requires more specialized components, but it provides three separate barriers against air and water infiltration. Because our innovative system integrates to your existing building paper, a true weathertight seal is created—one that passes AAMA pressure tests and can withstand 120 mph winds.

This system is so effective that we’ve never once had to make a service call, even with thousands of Seattle and Tacoma replacement windows installed!
