Sealing and weatherproofing windows are essential in the full-frame window replacement installation process, ensuring optimal performance and longevity. By adequately sealing windows, homeowners can prevent air and water leakage from the original window frame, enhance energy savings, and maintain a comfortable indoor environment.
To seal windows effectively, it is crucial to use a 3/8-inch bead of sealant around the edges of the opening. This creates a tight seal that prevents air and moisture infiltration through wooden windows. Additionally, leaving a 3/4-inch gap on each side of the corners allows for installing corner gaskets for a high-quality, consistent fit. These gaskets provide extra protection against drafts and water penetration, enhancing the window’s weatherproofing capabilities and energy savings.
One important note is to avoid caulking under the bottom nailing flange. This area must remain uncaulked to allow any potential water entering the window frame to drain correctly. For window installations, exterior grade "Window, Door, and Siding" sealant is recommended. This specialized sealant is designed to withstand exterior conditions, providing superior protection against harsh weather elements like rain, wind, and UV rays while ensuring a high-quality, consistent fit.
