Frequently Asked Questions

How can I tell if I need new windows or if my current windows are functioning well?

There are four easy ways to determine if you need new replacement windows.

  1. Touch Test
    On a cold day, touch the pane of glass on your current windows; if the glass temperature is equal to the outside temperature that probably means that your windows are not efficient and could be letting cold air in and the warm air out.
  2. Match Test
    Light a match and carefully trace your window pane. If the match flickers or blows out then you have an air infiltration issue and are letting out precious heat.
  3. Look Test
    Look at your windows and see if there are any foggy areas. This could mean that your windows aren’t sealed properly.
  4. Lift Test
    Try quickly opening your window. If you struggle or windows are stuck, then it may be time to replace them.

Starting with these window tests on your current windows will help you assess the performance of your current windows. If you have any concerns, call the Zen Windows professionals for a professional window evaluation.

What makes windows energy efficient?

Windows that are graded as energy efficient substantially seal out air and water infiltration. These windows protect from outside air entering the home or air from leaving the home.
