What is a good U-Factor for a window?
Introducing our high-performing windows, meticulously engineered to meet regional weather and building regulation requirements while maximizing the energy efficiency of your home.
Guided by the international ENERGY STAR® program, our windows are designed to maintain a U- Factor of 0.27 or lower for colder climates, reducing heat loss to the minimum, cutting energy costs and ensuring your indoors remain cozy during chilling winters.
For our customers in warmer locales, the windows come with a U-factor of 0.40 or lower, effectively keeping your interior cool by limiting the amount of heat that seeps into your home. Our windows are not only designed to be energy-efficient, but they also enhance your space aesthetically.
Striking the right balance between performance and visual appeal, these windows are the perfect addition to your home or office!
