It will take less energy to heat your home in the winter, or cool your home in the summer. Energy savings is realized thanks to the modern design of today’s new windows and doors. Furthermore, back when your old windows and doors were installed, installers did not use insulation foam to fill the void between the framing of your home and the old windows and doors that were likely installed with the original construction of your home. Replacing old windows and doors now, will allow us to ensure proper installation using insulating foam.
