Low-emissivity (Low-E) glass has become a key feature in modern construction. It enhances thermal insulation and reduces energy consumption while allowing natural light to enter. In this article, we will explore what Low-E glass is, how it works, and its main advantages.
As a leader in custom windows and doors, Unisson Groupe integrates Low-E technology into our products to meet the growing demand for comfort, energy efficiency, and sustainability. Whether you’re building new or upgrading your existing windows, understanding the benefits of Low-E glass is essential to making informed choices for your home.
1. What Is Low-E Glass?
Low-E (Low Emissivity) glass is coated with an ultra-thin metallic layer that reduces heat loss while letting light pass through. This coating reflects indoor heat back inside during winter and prevents excessive heat from entering during summer.
2. The Benefits of Low-E Glass
- Improved thermal insulation: Reduces heat loss in winter and limits overheating in summer.
- Energy savings: Reduces heating costs in winter and air conditioning expenses in summer.
- UV protection: Blocks up to 99% of ultraviolet rays, preventing furniture and flooring from fading.
- Enhanced comfort: Reduces cold drafts near windows during winter.
3. How to Choose the Right Low-E Glass?
When purchasing windows with Low-E glass, consider the following:
- U-factor (thermal transmittance coefficient): The lower it is, the better the insulation.
- Solar heat gain coefficient (SHGC): Measures the amount of solar heat transmitted indoors.
- Type of gas between the panes: Some Low-E windows contain argon or krypton gas for added insulation.
Conclusion
Low-E glass is an excellent choice for homeowners looking to improve thermal comfort and reduce energy consumption. Investing in Low-E windows means a more energy-efficient and comfortable home. At Unisson Groupe, we specialize in providing custom, high-performance window solutions featuring Low-E technology — designed to enhance your home’s comfort and efficiency all year round.
