Finally, for windows and doors to provide optimal energy efficiency, they must be flashed, caulked and sealed properly at the time of installation. All of our products are shipped with detailed installation instructions, which emphasize the importance of these final steps. Once properly installed, the energy efficient technology built into Kolbe products will further ensure your design project provides all the benefits of a healthy and comfortable living or working environment.
