Imagine coming home on a frigid Canadian winter day to find your house cozy and warm, without cranking up the thermostat. What if we told you that the secret to comfort and serious savings on your energy bills could be right in front of you—energy-efficient windows?
Let's break down how these high-tech windows work their wonders, from cutting your energy costs to making your house more valuable.
What Makes Windows Energy-Efficient?
Energy-efficient windows include several key features that work together to reduce heat transfer and enhance insulation.
Low-emissivity (Low-E) coatings: These microscopically thin, transparent layers reflect heat while allowing light to pass through.
Multiple panes: Double or triple-glazed windows with air or gas-filled spaces between panes provide better insulation than single-pane windows.
Insulating gas fills: Argon or krypton gas between panes further enhances insulation properties.
Warm edge spacers: These separate glass panes and reduce heat transfer at window edges.
Insulating frames: Materials like vinyl, fibreglass, or wood offer better insulation than traditional aluminium frames. Don't knock High Performance Aluminum, these are built with the energy efficiency of homes in mind.
What type of window is Energy Efficient?
Energy-efficient windows are a key feature in modern homes, with their large openings and glass sizes, offering significant benefits in terms of energy savings and comfort. These windows use advanced technologies to minimize heat transfer, helping to maintain consistent indoor temperatures and reduce the load on heating and cooling systems. By understanding the various types and features of energy-efficient windows, homeowners can make informed choices to improve their property's energy performance. Let's explore the common types of energy-efficient windows and their key characteristics:
Double-Pane Windows
Double-pane windows, also called insulated glass units (IGUs), have two glass panes with a layer of air or gas between them. They are sealed using a spacer. Once in a frame the unit creates a barrier that reduces heat transfer, making your home better insulated.
Low-E Coated Windows
Low-emissivity (Low-E) coatings are thin layers that are baked into the glass to help regulate temperature. These coatings are sealed inside the unit, they can't be scratched or wiped away with cleaning. These coatings reflect heat while allowing light to pass through. With the option to add different levels of Low-E you can increase the efficiency of the unit. Reducing heat loss in winter and minimizing heat gain in summer by up to 50%. This keeps your home warmer in winter and cooler in summer.
Gas-Filled Windows
Some windows have inert gases like argon or krypton between the glass panes instead of air. These gases are denser than air, which makes them better at reducing heat transfer. Not all gas is created equal, due to the size of the molecules, is most effective in a double glazed unit, while krypton is best in triple units. With today's economy using krypton has become almost obsolete, due to the high cost. Save your pennies on the krypton and add an extra layer of LoE coating, your home will thank you.
Frame Materials
While the glass and its coatings play a crucial role in a window's energy efficiency, the frame material is equally important. The right frame can significantly enhance a window's insulating properties, contributing to overall energy savings and comfort. Different frame materials offer various benefits in terms of durability, maintenance, and thermal performance. Let's explore some of the most common and energy-efficient frame materials:
Vinyl Frames
Vinyl frames insulate well and don't need much maintenance. Vinyl is a popular choice for energy-efficient windows due to its excellent insulating properties. Made from PVC (polyvinyl chloride), vinyl frames are resistant to moisture, rot, and corrosion. They have hollow chambers that can be filled with insulation, further improving their thermal performance. Vinyl frames are also cost-effective and require minimal upkeep, making them an attractive option for homeowners seeking long-term value.
Aluminum Wood Clad Frames
Aluminum-clad wood windows combine the strength and weather resistance of aluminum on the exterior with the natural insulating properties of wood on the interior, resulting in a highly energy-efficient window option.
The combination of aluminum cladding and wood allows these windows to perform well in various climates. The aluminum exterior withstands harsh weather conditions, while the wood interior provides insulation in both cold and warm climates
By combining the thermal benefits of wood with the durability of aluminum and incorporating advanced glazing technologies, aluminum-clad wood windows offer homeowners an energy-efficient solution that doesn't compromise on style or longevity.
Aluminum Frames
Aluminum frames are remarkably lightweight compared to other materials like steel, making them easier to handle, transport, and install. Despite their low weight, aluminum frames offer excellent strength and durability, with a high strength-to-weight ratio that allows them to withstand various loads and stresses
When properly designed with thermal breaks, aluminum frames can provide excellent thermal efficiency. This feature helps in maintaining indoor temperatures and reducing energy costs associated with heating and cooling
Aluminum frames require minimal maintenance compared to other materials like wood. They typically only need cleaning with mild soap and water to keep them looking pristine. Additionally, powder-coated aluminum frames don't require repainting, further reducing maintenance needs
Most Efficient Window Style
Fixed or picture windows are typically the most energy-efficient because they don’t open, allowing for a complete seal. However, they don't allow for ventilation. For windows that open, casement and awning styles are usually more energy-efficient because they close tightly against the frame. By choosing energy-efficient windows, you can make your home more comfortable and reduce your energy bills. It's important to consider your specific needs, climate, and budget when selecting windows for your home.
