Understanding Window Specifications: Making an Informed Choice with Dual Action Windows

Updated: Apr 23

When shopping for windows, it's crucial to understand technical specifications like U-Value, SHGC (Solar Heat Gain Coefficient), and VT (Visible Transmittance). These factors significantly impact your home’s comfort, energy efficiency, and natural light.

U-Value: The Key to Insulation

U-Value measures a window's ability to prevent heat escape. Dual Action Windows offers options with U-Values as low as 0.14, surpassing the typical Energy Star ratings of 0.20-1.20. A lower U-Value means better insulation, leading to energy savings.

SHGC: Tailored for Your Climate

SHGC indicates how much solar heat passes through a window. A higher SHGC is beneficial in colder climates as it helps harness solar heat, reducing heating costs. Conversely, in warmer climates, a lower SHGC is preferable to keep interiors cool and reduce air conditioning needs.

VT: Brighten Up Your Space

VT measures how much natural light penetrates through the window. Higher VT values ensure more daylight and a brighter interior.

With over 150 glazing options, Dual Action Windows lets you choose the right U-Value, SHGC, and VT for your specific climate needs, ensuring comfort, energy efficiency, and ample natural light in your home.
