Energy Efficient Doors & Windows

Maximize your energy efficiency month after month

Maximize your energy efficiency month after monthWhen you’re building your dream home, don’t let your energy bills turn into a nightmare. The right windows and doors can help minimize your cooling costs because your central air conditioner won’t have to work so hard to keep your home comfortable.
So, how do you know if a window or door is energy-efficient? Look for these features:
  • Multiple panes of glass
Double-pane glass insulates almost twice as well as single-pane. Triple-pane glass maximizes your energy efficiency.
  • Low-E (Low-emissivity) glass coatings
These are layers of thermal protection inside insulating glass that:
Help reflect summer heat and retain interior cooling. Help prevent fade damage.
  • Argon1 (inert gas) between the glass panes

Argon is a natural, colorless, non-toxic gas that’s heavier than air. It adds a layer of insulation to further reduce heat transfer, making your home even more energy-efficient. Pella® products offer the energy efficient options that will meet or exceed ENERGY STAR® guidelines in all 50 states.2

  • An Energy-Efficient Window FrameAn Energy-Efficient Window Frame
Wood frames are excellent insulators — they conduct less heat or cold into your home. In fact, they insulate 1,800 times better than aluminum. Fiberglass composite material offers the insulating properties of wood. It won’t expand and warp in the summer, or shrink and turn brittle during winter. Vinyl multi-chambered frames reduce heat loss for added energy efficiency ― and they’re exceptionally easy to care for. Aluminum is inexpensive and durable but has a poorer insulation rating, meaning the frames conduct more heat or cold into your home.
  • Tight Seals
Windows and doors that don’t seal properly are drafty — affecting your comfort level and increasing your energy costs. Rest assured, Pella tests its products in state-of-the-art facilities to make sure they meet or exceed industry performance standards.
  • Quality Installation
If installed incorrectly, your windows and doors may not operate properly. Proper installation will help prevent air infiltration and even costly water damage to your home.
  • The NFRC labelThe NFRC label
It’s the only reliable way to determine the window’s (whole unit) energy performance and to compare products “apples to apples.”
The National Fenestration Ratings Council (NFRC) is a nonprofit organization for the window industry that developed an energy rating system based on whole-unit product performance — not just the glass.
A The U-Factor represents the rate of heat flowing out of a window or door in an hour’s time. The lower the number, the better the glass insulates.
B The Solar Heat Gain Coefficient (SHGC) rating measures the amount of solar radiation that enters as heat. The lower the number, the less heat the glass allows in.
