What is R Value?

When renovating your home, it’s important to understand what R value means, especially in windows and doors. By knowing what R value means, you can make informed decisions on what windows and doors will help improve energy efficiency in your home.

Newly installed windows with high R value

What Does R Value Mean?

R value measures the resistance of a material to heat transfer. In the case a new window or door installation, a higher R value (or R factor) indicates a higher level of insulation. This means that windows and doors with a higher R value will keep your home warmer in the winter and cooler in the summer, leading to improved energy efficiency.

How is R Value Calculated?

The R value of windows and doors is influenced by several factors, including the material used, glazing, and frame type. Typically, the R value is calculated by dividing the window or door’s thickness by the material’s thermal conductivity. The higher the R value, the better the insulation properties.

What is an Ideal R Value?

The ideal R value for windows and doors varies based on the climate in which you live. In colder areas, like we see in southwestern Ontario, a higher R value is typically recommended to keep your home warm during the winter months. A lower R value may be sufficient to provide adequate insulation in milder climates.

The Benefits of High R Value Windows and Doors

When you opt for new windows or doors with a high R value, you will see several benefits, such as:

  • Improved energy efficiency
  • Lower energy bills
  • Increased home comfort
  • Improved home value

High R value windows and doors can help you save money on heating and cooling costs while reducing your carbon footprint by keeping out drafts and preventing heat from escaping in the cooler months.

Choosing Energy-Efficient Windows and Doors

When choosing energy-efficient windows and doors, there are several factors to consider. In addition to selecting an option with a high R value, it’s important to look for windows and doors with insulated frames and double or triple-pane glass. Low-E coatings can also help improve energy efficiency by reflecting heat and preventing it from escaping through the glass.
