What are Energy Efficient Windows, and How do They Work?
Energy-efficient windows are designed to minimize heat transfer between the interior and exterior of a building, reducing energy consumption for heating and cooling. They feature low-emissivity (Low-e) glass coatings, which reflect infrared light while allowing visible light to pass through, reducing heat gain in hot weather and heat loss in colder seasons. These windows often incorporate multiple panes of glass with insulating gas fills, like argon or krypton, creating a barrier against heat transfer and improving thermal efficiency.
High-quality window frames are made from vinyl to minimize air leakage and provide additional insulation. Overall, energy-efficient windows work by effectively reducing heat transfer, improving insulation, and optimizing the energy performance of buildings. This results in lower energy bills and increased comfort for occupants, making them a valuable investment for homes and buildings seeking to improve energy efficiency and reduce environmental impact.

Triple Glass
Three panes of glass compared to a double pane: what's the difference? Big City Windows & Doors triple pane glass provides the best energy efficiency on the market. While our insulating frames work to keep hot air in during winters and out during summers, our Low-E coatings increase the retention of solar gain. This results in the ultimate jack- of-all-trades energy efficient window model.
Low-E Glass
Low-emissive coatings applied to the panes of glass make your windows more energy efficient and can lead to lower energy bills. Low-E glass helps keep the heat in during winters and out during summers for a comfier, more affordable home all year long. We offer different Low-E glass options to provide different levels of heat reflection to better suit your home. Finally, Low-E glass windows minimize harmful ultraviolet light which helps avoid warping, cracking, and discolouration.

What are Energy Efficient Windows, and How do They Work?
The potential savings for a property owner through the installation of energy-efficient windows can vary depending on factors such as the size of the property, local climate conditions, energy costs, and the efficiency of the windows installed. However, studies suggest that replacing old, inefficient windows with energy-efficient ones can lead to significant cost savings over time.
25%
On average, homeowners can expect to save anywhere from up to 25% on their heating and cooling costs by upgrading to energy-efficient windows.
For example, a homeowner with high energy bills due to inefficient windows might see a reduction of hundreds of dollars annually after installing energy-efficient replacements.
These savings accrue due to several factors. Energy-efficient windows help to better insulate the home, reducing the need for heating in winter and cooling in summer. They minimize heat transfer through low-emissivity coatings, multiple panes, and insulating gas fills, maintaining a more consistent indoor temperature year-round. Additionally, improved sealing and insulation provided by quality window frames prevent air leakage, further enhancing energy efficiency.
Over time, these reduced energy costs can offset the initial investment in energy-efficient windows. Moreover, many governments and utility companies offer incentives, rebates, or tax credits for energy-efficient home upgrades, further reducing the upfront costs and increasing the long-term savings potential.
Ultimately, installing energy-efficient windows not only contributes to lower energy bills, but also enhances comfort, reduces environmental impact, and increases the overall value of the property.
FREQUENTLY ASKED QUESTIONS ABOUT Energy Efficient Windows IN OTTAWA
Are there government incentives or rebates available for installing energy-efficient windows?
Government and utility companies generally offer incentives, rebates, or tax credits for installing energy-efficient windows. These incentives aim to encourage homeowners to make environmentally friendly upgrades that reduce energy consumption and lower greenhouse gas emissions.
Do energy-efficient windows provide any sound insulation benefits?
Yes, energy-efficient windows can provide some degree of sound insulation, especially when compared to older, single-pane windows. The multiple panes of glass and insulated frames help reduce outside noise infiltration, creating a quieter and more comfortable indoor environment.
Do energy-efficient windows offer UV protection for my furnishings and interior?
Many energy-efficient windows are designed to block a significant portion of ultraviolet (UV) rays from entering the home. This helps protect furnishings, flooring, and interior décor from fading and damage caused by prolonged exposure to sunlight, prolonging their lifespan and reducing the need for replacement or refurbishment.
What is the typical payback period for energy-efficient windows in terms of energy savings?
The typical payback period for energy-efficient windows varies depending on factors such as the cost of installation, local energy prices, and climate conditions. However, homeowners can generally expect to recoup their investment within 5 to 10 years through reduced energy bills.
What is the expected lifespan of energy-efficient windows, and do they require special maintenance?
Energy-efficient windows typically have a lifespan of 20 to 30 years or more, depending on the quality of materials and installation. While they may require occasional cleaning and maintenance, such as lubricating hinges and seals, they generally do not require special maintenance beyond what is recommended for standard windows.
