LOW-E Glass FAQ
Q: What does LOW-E stand for in LOW-E glass?
A: LOW-E stands for low emissivity. It refers to a microscopically thin, transparent coating that reflects infrared energy (heat) while allowing visible light to pass through. This coating dramatically improves the thermal performance of glass.
Q: How does LOW-E glass help with energy savings?
A: LOW-E glass reduces heat transfer through windows by reflecting interior heat back inside during winter and blocking exterior heat during summer. This results in reduced HVAC usage and energy bills. Tests show buildings with LOW-E glass can achieve 30-50% energy savings compared to standard glass.
Q: Is LOW-E glass more expensive than regular glass?
A: While LOW-E glass carries a 15-30% premium over standard glass, the energy savings typically pay back the additional cost within 3-5 years through reduced utility bills. The long-term benefits make it a cost-effective investment for both residential and commercial buildings.
