Hundreds of years ago, the idea of glass windows themselves was quite modern and luxurious. Now, glass is the bare minimum when it comes to windows. These days, single-pane windows no longer cut it. Too much heat is lost through the panes of glass in winter, and too much heat gets in during the summer. Old wooden frames can become worn down, rotten, and swollen. Simple vinyl frames can be too easily breakable. The truth is that old, outdated windows can easily lose your home more money than they’re worth in terms of your energy bills, home value, and security. Modern homeowners need modern windows and doors.
