What makes a patio door energy-efficient? As a homeowner, it’s essential to understand the characteristics of energy-efficient doors and windows, especially in extreme climates. While an attractive design and a secure lock are necessary, much of their value also lies in their energy-saving capabilities. Continue reading to learn more about the features that make a patio door energy-efficient.

Quality Construction
Energy-efficient patio doors have a robust construction to ensure durability, as gaps or weak points could let in drafts, compromising insulation. Look for materials that are resistant to warping, cracking and fading.
- Vinyl or Fiberglass Frames – Both materials offer excellent insulation properties and require minimal maintenance. They are less susceptible to temperature fluctuations, providing better protection against heat loss and gain.
- Multi-Chambered Frame Design – A multi-chambered frame traps air as a thermal barrier that helps insulate the patio door.
Energy-Efficient Glass
Glazing plays a significant role in the overall efficiency of a patio door. The type and quality of glass can dramatically impact energy consumption.
- Double- or Triple-Pane Glass – Energy-efficient patio doors usually feature double- or triple-pane glass, providing better insulation than single-pane glass. The extra panes create additional barriers that make it harder for heat or cold to penetrate indoors.
- Low-E Glass Coating – A low-emissivity (Low-E) coating is a thin, invisible layer applied to the glass panes. This coating reduces heat transfer by reflecting or absorbing thermal energy, preventing heat loss in the winter and heat gain in the summer.
- Argon or Krypton Gas Fill – The air space between the glass panes can be filled with inert gas, such as argon or krypton. These gases are denser than air and more effective at reducing heat transfer, making them ideal for insulation.
Advanced Weatherstripping
Quality weatherstripping can prevent leaks and drafts, contributing to better insulation. Pay attention to the gaskets, seals and other materials used in the design to ensure long-lasting, energy-efficient performance.
Proper Installation
Even the most energy-efficient patio door won’t perform well if improperly installed. Proper installation by a professional door and window replacement contractor is crucial to achieving a snug, draft-free fit. Always follow the manufacturer’s instructions or hire a professional installer to ensure optimal performance.
