How the Right Door Can Boost Your Home’s Energy Efficiency (Northwest Indiana Guide)

When homeowners in Northwest Indiana and Michiana think about cutting energy costs, windows and insulation usually get all the attention. But there’s another major player: your exterior doors.

At Terry’s Discount Windows & More, we’ve helped countless homeowners across the region improve their home’s comfort and lower utility bills-just by upgrading to energy-efficient doors.

Here’s how the right door can make a real difference in your energy efficiency (and your wallet).


Why Doors Matter More Than You Think

Your front, back, or patio doors do more than just welcome guests – they help seal your home from the outside elements. If your door is old, warped, poorly installed, or just not energy efficient, it could be:

  • Letting in cold drafts during Indiana winters
  • Allowing cool air to escape during the summer
  • Causing your HVAC system to work harder

That adds up to higher energy bills and less year-round comfort – especially in towns like Valparaiso, Crown Point, and South Bend, where weather swings can be dramatic.


What Makes a Door Energy Efficient?

When it’s time for a new door, here’s what to look for to maximize efficiency:

✅ Insulated Core

Doors made with fiberglass or steel and insulated with polyurethane foam are excellent at reducing heat transfer.

✅ High-Quality Weatherstripping

A tight seal around the edges of the door prevents drafts and helps maintain a consistent indoor temperature.

✅ Low-E Glass

If your door has windows or is a sliding glass door, make sure it features Low-E (low-emissivity) glass. This helps reflect heat in summer and retain warmth in winter.

✅ ENERGY STAR® Rated

Look for ENERGY STAR-certified doors that are designed for our specific Midwest climate zone—guaranteed to perform well in both hot and cold conditions.


How Much Can You Really Save?

An energy-efficient door, professionally installed, can cut heat loss by up to 30%. In real numbers, that means potential annual savings of $100 to $400 on your energy bills, depending on the size and condition of your home.

It’s one of the most cost-effective upgrades you can make – and it’s also a great opportunity to refresh your home’s curb appeal.


Best Door Options for Northwest Indiana Homes

At Terry’s Discount Windows & More, we offer a wide range of door styles to match your home and energy needs, including:

  • Fiberglass Entry Doors – Durable, stylish, and ultra-insulated
  • Steel Doors – Strong and secure with foam-core insulation
  • Sliding Glass Doors – Perfect for patios with insulated glass panels
  • French Doors – Elegant and energy-efficient when properly sealed
  • Storm Doors – Add a second layer of insulation and protection

Professional Installation Makes All the Difference
