Most normal windows are thermal holes, causing an average home to lose up to 30% of its heat or air-conditioning energy through its windows. As a result, windows are one of the most important components in creating an energy efficient home and have a huge impact on achieving Step Code compliance and Passive House ratings. As standards in energy efficiency increase, you will want to ensure your windows and doors are up to the highest level of effectiveness to ensure your home can continue to be ranked as Passive House or Step Code compliant over time. EuroLine Windows have exceptionally airight products and are already rated at the highest level of Energy Step Codes, exceeding the current standard for Step Code compliance in B.C.
