Energy Efficiency

The U-value, also known as the thermal transmittance, is a measure of how effective a building material (such as windows, doors, or walls) is as an insulator.

ROPO triple glazing is one of the highest performing glazing units on the market with an industry-leading 0.80 U-value making it ultra energy efficient. Choosing energy-efficient Everest windows can help lower your energy bills and reduce your carbon footprint.

At ROPO, We are Focused on Improving the Energy Efficiency of All Our Windows and Have Produced This Guide to Explain Everything You Need to Know U-Values and SHGC and What an Energy Efficient Window is Made From.

Double Glazed Windows are Constructed from a Frame and a Glazed Unit Featuring an Insulating Layer of Argon Gas Sandwiched Between Two Panes of Glass.
