Energy Efficient Windows & Doors

When it comes to selecting windows and doors, energy efficiency is one of the prime factors. Quality glass and manufacturing, as well as an excellent reputation, makes Pella Windows & Doors a strong choice for affordable, energy efficient replacement windows and doors. Pella offers products that meet or exceed ENERGY STAR requirements. For the fifth consecutive year, the U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE) announced Pella Corporation has earned the ENERGY STAR Partner of the Year award for their commitment to manufacturing energy-efficient products and educating consumers about them. Pella was also honored with the Sustained Excellence award, in recognition of their commitment to successfully managing energy use and promoting ENERGY STAR products and practices within the organization.

Creating Energy Efficient Windows & Doors

For weather proofing your home, Pella creates advanced energy efficient windows and doors. Pella windows and doors are tested for air infiltration in state-of-the-art facilities to make sure they seal properly and meet or exceed industry performance standards. By purchasing from Pella Windows & Doors, you will have windows and doors that help to make climate control easier and your environment more comfortable when dealing with fluctuations in temperature.

Pella utilizes the latest in materials like insulating glass with argon. This extra insulation helps keep the surface of the glass from getting too hot or cold, keeping your environment more comfortable. Pella also uses multiple layers of glass coating which help with the temperature as well as protecting your furniture and window treatments from fading.

Pella Windows also employs an expertly trained and certified installation team. This team utilizes a tested installation method to be certain your windows are performing at their best.

What makes Pella's doors and entry systems energy efficient?

energy efficient doors

Pella’s energy-saving technology can make a major difference in your comfort and energy use because we:

  • use multiple panes of glass
  • apply Low-emissivity (Low-E) glass coatings which reflect heat energy
  • insert Argon between the panes of glass to provide extra insulation from the heat and cold.
  • have a variety of features and options with snap in shades and blinds that serve as an extra insulation layer.

Also, Pella’s sliding patio doors feature our unique design that puts the sliding panel on the exterior — so the harder the wind blows, the tighter the seal.

Pella Lifestyle Series is the #1 performing wood window and patio door for the combination of energy, sound and value1. Pella Lifestyle Series has options that are on average 79% more energy efficient than single-pane windows2. Our exclusive snap-in between-the-glass blinds or shades can help increase the energy savings as well. They add an extra layer of insulation between the glass, helping to keep your home warmer in winter and cooler in the summer.

The frame material of your door plays an important role in how well the door insulates your home from outdoor cold or heat. For example, wood is an outstanding insulator — it insulates 1,800 times better than metal. Pella’s Duracast® fiberglass composite offers an insulating value similar to wood. Vinyl is less insulating in nature, but Pella’s vinyl patio doors have air chambers inside the vinyl to increase its insulating ability. Aluminum does a poor job of insulating — it transfers the heat or cold into your room, so it can be uncomfortable to sit next to an aluminum window or door.

More about energy efficiency

1.  Performance solutions require upgrades to triple-pane, AdvancedComfort Low-E and mixed glass thickness. Based on comparing product quotes and published STC/OITC and U-Factor ratings of leading national wood window and patio door brands 
2. Performance solutions require upgrades to triple-pane and AdvancedComfort Low-E. Window energy efficiency calculated in a computer simulation using RESFEN 6.0 default parameters for a 2000 sq. foot new construction single-story home when comparing Pella Lifestyle Series windows to a single-pane wood or vinyl window. Double-hung windows are not available with triple-pane glass. The energy efficiency and actual savings will vary by location. The average window energy efficiency is based on a national average of 94 modeled cities across the country and weighting based on population. For more details see pella.com/methodology
