Starline Windows, a leader in quality window manufacturing for over 40 years, has developed a window system to meet the needs of new building codes and the Best Practices Guide from C.M.H.C. Equal pressure cavity wall construction is gaining popularity with progressive contractors, envelope specialists and city planning departments.
The equal pressure cavity wall design greatly reduces the chance of water passing through the wall's outer skin.
Geometric problems made it difficult to install conventional nail-on window designs into the new concept of a 20 mm drainage cavity wall. Our RainShield window system has an extra 25 mm of frame projecting out from the nailing flange for a total of 45 mm. This improved design allows us to locate the frame in its proper location, nailed to the wall sheeting, and still project out to completely cover the wall's cladding component, be it stucco, wood, cement or vinyl.
The RainShield system not only accommodates a thicker wall skin, it is also easier to install and maintain. With improved flashing, low maintenance gaskets and an extended main frame to tie in more efficiently with equal pressure cavity walls, the RainShield system is the perfect answer to new building construction. In addition, the system also incorporates a built-in sloped sub-sill, which in conjunction with a peel & stick application at the still, creates a "bathtub" under the window frame to drain out any incidental water that gets into the equal pressure cavity wall.
