Low-E Windows are the Best Choice for Ottawa Buildings

In Ottawa, where we experience a mix of cool winters and warm summers, maintaining energy efficiency in your home is crucial. Dundela Window and Door offers an extensive range of Low-E windows designed to enhance your home’s comfort while significantly lowering energy costs throughout the year.

What are Low-E Windows and How Do They Work?

Energy Savings All Year Round

  • Summer Benefits: Low-E windows reflect excessive solar heat, reducing the need for air conditioning and cutting down on cooling expenses.
  • Winter Benefits: The coating retains indoor heat, lessening the need for heating and lowering your energy consumption.

Protection for Your Home’s Interior

Ultraviolet (UV) rays from the sun can cause fading and damage to your furniture, carpets, and other interior elements. Low-E windows block a substantial portion of these harmful rays, preserving your home’s interior and extending the life of your furnishings.

Selecting the Right Low-E Windows for Your Home

Choosing the correct Low-E windows involves considering the unique sun exposure each side of your home receives. Here’s a guide to help you make the best decision:

Optimizing Window Placement by Direction

  • North-Facing Windows: These windows should have a high R-value for better insulation, as they receive minimal direct sunlight. A mid-range Solar Heat Gain Coefficient (SHGC) is ideal.
  • South-Facing Windows: Maximize solar heat gain in winter while considering shade for summer. A high SHGC is recommended.
  • East-Facing Windows: These windows should balance insulation with light transmission. A mid-range SHGC works well.
  • West-Facing Windows: To combat the intense afternoon sun, choose windows with a low SHGC to minimize heat gain.

Single vs. Double Low-E Coatings

Another key consideration is whether to opt for single or double Low-E coatings. Single Low-E windows feature one layer of coating, while double Low-E windows offer two layers, providing superior thermal performance and greater energy savings.

Potential Drawbacks and Considerations

While Low-E windows offer numerous benefits, it’s important to be aware of potential drawbacks:

  • Reduced Visibility: Some Low-E coatings can slightly decrease visible light, which might not be ideal for areas requiring clear visibility.
  • Excessive Warmth: High solar gain coatings can lead to overheating in certain rooms, especially those with large windows or limited shading.
