Cascade U-Value

U-values measure the rate that heat transfers through a product. Therefore the lower u-value, the lower the heat loss and the better your home is insulated. Be sure to check the u-values on any window that you might be considering. Our specially coated EC and EC+ windows re ect outside heat in the summer and interior heat in the winter, reducing your air conditioning and heating requirements.
