This will keep the cold away in winter and keep you cool in summer. But if you can't do residential glass replacement, you can still improve the energy efficiency of existing windows. Windows and doors are the major sources of heat loss in most homes.
Here are some tips on how you can improve existing windows. First of all, you should start by checking for air intrusion or leakage around the window frame.
And this way you can find out if you have any gaps or cracks that allow hot or cold air to leave or enter the house. To do this, you should hold the back of your hand near the edges of the windows to track the source of the leak.
If you find that cool air is blowing through the back of the trim, chances are that the spaces around the window or door were not sealed properly.
