Energy-efficient Windows

A home’s windows serve many purposes, and one of the most important is the energy-efficiency they offer. Heating and cooling costs can go right out the window when you’re not paying attention. While replacing windows may offer the biggest improvement in efficiency, it’s not always feasible due to the high cost involved.

Here are two quick tips on ways to make existing windows more energy-efficient at a lower cost.

  1. Seal Air Leaks:
    Air can easily escape through gaps in the seals. Look for any light coming in around the window frame. If gaps are found, then use weather stripping or caulking to seal them. 

  2. Install Window Film:
    Energy-efficient window film adds an extra layer to the window.  The average cost to switch to energy-efficient windows is between $8,000 to $15,000. 

Whereas with a little bit of research (and a nominal amount of money out of your pocket), existing windows in your home can be made more efficient to help you reduce your energy bills and provide more comfort.
