Replacement Windows by Lakeside has published a new guide to help homeowners understand energy-efficient window ratings. This resource aims to simplify the selection process for those considering window replacement or installation.
Deciphering Key Energy Efficiency Metrics
The guide breaks down essential terms used in evaluating window performance:
U-Factor: This measures the rate at which a window conducts non-solar heat. A lower U-factor indicates better insulation properties.
Solar Heat Gain Coefficient (SHGC): SHGC assesses a window's ability to block heat from sunlight. A lower SHGC is beneficial in warmer climates to reduce cooling costs, while a higher SHGC can be advantageous in colder regions to allow more solar heat.
Air Leakage (AL): AL quantifies the amount of air passing through joints in the window assembly. Lower AL values signify tighter construction and reduced drafts.
The Importance of ENERGY STAR® Certification for Your Replacement Windows
The guide emphasizes the significance of selecting windows with ENERGY STAR® certification. Such windows are designed to enhance comfort, filter out harmful ultraviolet light, and contribute to energy savings. Features of these certified windows include:
Multiple Panes: Double or triple glazing provides a barrier against external temperatures.
Gas Fills: Inert gases like argon between panes improve insulation.
Low-E Glass: Low emissivity coatings reflect heat, aiding in temperature regulation and protecting interiors from UV damage.
Optimized Frame Materials: Frames designed to enhance insulation and reduce thermal bridging.
The Role of Proper Window Installation
Proper installation is crucial for maximizing the benefits of energy-efficient windows. Even the best windows can underperform if not installed correctly. Homeowners are encouraged to choose a reputable window contractor to ensure optimal performance and longevity.
