Energy Efficiency


All Tyee products meet Energy Star® standards.


Tyee’s high performance windows and doors will considerably lower energy costs and help reduce condensation and outside noise, while adding comfort and value to a home. Estimates show that most homes can reduce their household energy costs by 15% annually by installing more energy-efficient windows. Adding low emissivity (Low E) glass (standard on all Tyee windows) will protect the home’s interior even more by reducing harmful UV rays by up to 75%.


ENERGY STAR® is an internationally recognized program with strict certification standards that help consumers identify the most energy efficient products available.
