When it comes to energy-efficient windows, there are plenty of options to choose from. But not all windows provide the same level of performance. Energy-efficient windows are a great way to save money on heating and cooling costs. Along with the heat transmittance blocked by standard energy-efficient windows, the sun’s rays can also lead to glare and cause fading to your home furnishings. If you are looking for replacement windows that offer a superior level of sun protection for your Michigan home, consider Renewal by Andersen's High-Performance™ Low-E4® SmartSun™ Glass.
