New construction window installation is a critical step in building a home that combines aesthetics with energy efficiency. Unlike replacement windows, new construction windows come with a nail fin, a thin strip that frames the window, allowing it to be securely attached to the house frame. This feature ensures a tight seal, which is essential for preventing drafts and water infiltration.
Proper installation starts with accurately measuring the rough opening, which should be slightly larger than the window to accommodate shimming and leveling.
Once the rough opening is prepared, the window is set into place, and the nail fin is fastened to the exterior sheathing. This process requires precision to ensure the window is level and plumb, which is crucial for its operation and longevity. After securing the window, flashing tape is applied around the perimeter to create a watertight barrier. This step is vital in preventing moisture from seeping into the walls, which can lead to mold and structural damage. Insulating around the window frame with expanding foam further enhances energy efficiency by eliminating gaps that could allow air leakage.
The final step in new construction window installation involves adding the exterior and interior trims. The exterior trim not only provides a finished look but also adds an additional layer of protection against the elements. Inside, the trim covers the gap between the window and the wall, completing the installation. By following these steps, you ensure that your new construction windows will perform optimally, offering durability, energy savings, and aesthetic appeal. This meticulous approach to installation is essential for achieving the best results in any new build.
