As a homeowner, choosing the right replacement windows is a critical decision that can impact your home's energy efficiency, comfort, and overall appearance.

While there are many options available at stock stores such as Home Depot and Lowe's, professional window replacement companies that offer custom solutions, have different products and better energy efficiency. But is it really so important to spend so much extra when you can buy stock windows in seconds? Or waiting for new Canadian house windows to be manufactured specifically for your home worth the effort?

Today, we'll explore the various aspects of window quality and selection available at stock stores and professional companies, helping you make the best decision for your needs.

Window Types & Material Options Comparison

Both stock stores and professional replacement companies offer a variety of window types, but the selection may vary depending on the source. Common window types include:

  • Single-hung: Traditional windows with one movable sash, usually the bottom one.
  • Double-hung: Windows with two movable sashes, providing better ventilation options.
  • Casement: Hinged windows that open outwards, offering excellent airflow and unobstructed views. Best energy efficiency.
  • Awning: Hinged at the top, these windows open outwards, allowing for ventilation even during rain. Amazing strategic placement opportunities.
  • Sliding: Windows that glide horizontally, offering a sleek design and easy operation. Best for modern houses.
  • Bay and bow: A combination of three or more windows that project outward, creating additional living space and panoramic views.

Window frames can be made of different materials, including vinyl, wood, and fibreglass.

  • If you're looking for an affordable and low-maintenance option, vinyl windows are popular and can be bought in both stock and custom ways.
  • Wood windows offer a classic look and excellent insulation but may require more upkeep. Usually, it is pretty hard to tailor these units to various houses, so if you want these products, contacting a professional replacement company would be better.
  • Fibreglass windows can be a bit pricier but are durable, energy-efficient, and can mimic wood appearance.

If you're interested in higher quality or more diverse options, custom windows can provide additional choices to suit your home's specific needs better.

Features and Energy Efficiency: All You Need To Know

Energy-efficient windows can significantly reduce energy bills and make your home more comfortable. That's why replacing old windows with modern energy-efficient ones is usually why homeowners consider investing in this renovation. Modern glazing is the most important thing when it comes to thermal performance:

  • Double-pane: Windows with two layers of glass and an insulating gas layer, providing better insulation and noise reduction.
  • Triple-pane: Windows with three layers of glass and two gas layers, offering maximum insulation and noise reduction. These units might be up to 55% more energy efficient than regular units
  • Low-E coatings: Special coatings applied to the glass to reflect heat and UV rays, helping to maintain a consistent indoor temperature.

Moreover, there is one more important thing that makes energy-efficient windows – gas fillings. They are placed between panes and can be either argon or krypton, with the latter providing better insulation. Both stock stores and professional companies offer windows with various efficiency features, but custom solutions from specialized companies often come with higher energy-saving potential.

For example, you can always choose the number of panes, Low-E coatings, gas and other features to manufacture the best windows for your specific region.

Moreover, only custom windows are treated as energy efficient by government initiatives that support homeowners with rebates and grants for home renovations.

Check for the Energy Star rating when evaluating windows for energy efficiency. This rating ensures that the window meets the minimum performance standards set by the government.

What About Durability and Maintenance?

Window quality significantly impacts durability and maintenance requirements. Stock stores may offer budget-friendly options, but professional companies often provide higher-quality windows that last longer and require less upkeep. It's essential to consider the long-term costs of window replacement, including maintenance and potential energy savings.

  • Vinyl windows, for example, are known for their durability and low-maintenance requirements, while wood windows may need regular painting or staining to maintain their appearance.
  • Fibreglass windows offer a great balance of durability and energy efficiency but may come at a higher initial cost.

By selecting windows from professional companies, you can often get better warranties, ensuring long-lasting performance and peace of mind.
